Amaranth seed buying and growing guide

Grow Red Garnet Vegetable Amaranth

Red Garnet amaranth is a fast-growing warm-season leafy vegetable cultivated for its vivid red foliage, edible young leaves and ornamental garden value. It can be harvested as tender baby leaf, picked progressively for mature cooked greens or allowed to develop into a tall flowering plant.

Seedmart supplies Amaranth Red Garnet seeds for home gardens, raised beds, containers, market gardens and specialty leafy-green production. This variety is botanically classified as Amaranthus tricolor and is also associated with common names such as leaf amaranth, Chinese spinach, tampala and bayam.

Red Garnet is particularly useful when hot weather becomes unsuitable for cool-season crops such as English spinach. For the best eating quality, harvest young foliage regularly before the leaves and stems become coarse.

Why Grow Red Garnet Amaranth?

Thrives in Warm Weather

Vegetable amaranth grows actively through spring and summer when many cool-season leafy greens begin flowering or declining.

Vibrant Red Foliage

Red Garnet produces richly coloured leaves that add contrast to edible gardens, mixed plantings and market displays.

Fast Leaf Production

Tender baby leaves can be harvested considerably earlier than fully mature plants.

Repeated Harvests

Young leaves and shoots can be picked progressively while plants remain vigorous and vegetative.

Suitable for Containers

Amaranth can be grown in large pots, troughs, raised planters and compact urban gardens.

Packet and Larger Quantities

Choose smaller quantities for household growing or larger packs for repeated and market-garden sowings.

What Is Amaranth?

Amaranth is the common name for a diverse group of plants in the genus Amaranthus. Different species and varieties may be grown for edible leaves, mature grain-like seeds, ornamental flowers, livestock forage or garden colour.

The Seedmart product in this category is Red Garnet vegetable amaranth, classified as Amaranthus tricolor. It is grown primarily for its colourful edible foliage rather than as a specialist grain crop.

Amaranth plants generally produce:

Edible Young Leaves

Tender foliage can be harvested for stir-fries, soups, curries and other cooked leafy dishes.

Colourful Stems and Foliage

Red Garnet develops red to burgundy colouring that gives productive gardens an ornamental appearance.

Small Mature Seeds

Plants allowed to flower can produce numerous small seeds, although leaf varieties are not necessarily the best choice for commercial grain production.

Warm-Season Growth

Vegetable amaranth prefers warm soil and active summer growing conditions.

Amaranth is a crop group rather than one single vegetable. Check the species and variety before buying seed because leaf, grain and ornamental amaranths are selected for different purposes.

What Are Amaranth Seeds?

Amaranth seeds are the small seeds produced by mature Amaranthus flowers. Depending on the variety, they may be used for planting, grain production or food processing.

The seeds offered on this category page are supplied as planting seed for Red Garnet vegetable amaranth. They are intended to produce leafy plants with red edible foliage.

Planting seed should be used according to the product specifications. It should not automatically be treated as culinary grain simply because some amaranth species produce edible grain.

Amaranth Seed Type Primary Purpose Important Distinction
Vegetable amaranth seed Growing plants for edible leaves and shoots Selected primarily for foliage quality, colour and leaf production.
Grain amaranth seed Producing mature grain-like seed Selected for seed yield, seed colour and grain harvest.
Ornamental amaranth seed Flowers, foliage colour and landscape display Not every ornamental variety is selected for vegetable quality.
Culinary amaranth grain Cooking, milling or food production Food grain is not necessarily tested, labelled or suitable for sowing.

Vegetable Amaranth vs Grain Amaranth

Vegetable and grain amaranths belong to the same broad plant genus but are cultivated and harvested differently.

Vegetable Amaranth Grain Amaranth
Grown primarily for tender leaves and shoots. Grown primarily for mature dry seed.
Harvest begins while plants are young and actively growing. Plants are allowed to flower and complete seed development.
Leaf tenderness, colour and regrowth are important traits. Seed yield, seed size and maturity are important traits.
Commonly used as a cooked leafy vegetable. Seed may be cooked as a grain, popped or milled into flour.
Red Garnet Amaranthus tricolor is a vegetable-leaf type. Commercial grain production commonly uses varieties selected specifically for seed harvest.
Red Garnet is best positioned as a leafy vegetable. Although mature plants can produce seeds, this category should not promise the performance of a specialist commercial grain-amaranth variety.

Is Amaranth the Same as Spinach?

Amaranth is not true spinach. The name Chinese spinach refers to its culinary use as a leafy green rather than a botanical relationship with English spinach.

True spinach is Spinacia oleracea and prefers cool to mild conditions. Red Garnet amaranth is Amaranthus tricolor and performs best during warm weather.

Red Garnet Amaranth English Spinach
Botanical name: Amaranthus tricolor. Botanical name: Spinacia oleracea.
Prefers warm soil and summer growing conditions. Prefers cool to mild growing conditions.
Develops upright growth and can become a tall plant. Forms a relatively low leafy rosette.
Red Garnet produces red to burgundy foliage. Most spinach varieties produce green foliage.
Young leaves are commonly cooked like other Asian greens. Baby leaves are commonly eaten raw or cooked.
Useful as a warm-season leafy crop. Commonly grown through autumn, winter and spring.

Other Names for Vegetable Amaranth

Amaranth is grown across many countries and cuisines, so the same or related leafy crops may appear under several names.

Common names associated with vegetable amaranth include:

  • Leaf amaranth
  • Chinese spinach
  • Red amaranth
  • Tampala
  • Bayam
  • Callaloo, although this name can also refer to other leafy plants
  • Chaulai or related regional names
  • Amaranthus greens

Common names are not always botanically precise. When identifying or purchasing a crop, use the botanical name and variety alongside the common name.

Are Amaranth Leaves Edible?

Yes. The leaves of recognised vegetable-amaranth varieties such as Red Garnet are edible.

Young leaves and tender shoots provide the best texture. Older foliage and stems can become tougher and develop a stronger flavour as the plant matures.

Vegetable amaranth is commonly:

  • Stir-fried
  • Steamed
  • Added to soups
  • Cooked in curries
  • Combined with garlic, onion, chilli or ginger
  • Used as a warm-season alternative to spinach

The leaves are generally best treated as a cooked green. As with many leafy vegetables, preparation and serving practices may vary according to the cuisine and individual dietary requirements.

What Does Red Amaranth Taste Like?

Young Red Garnet leaves have a mild green flavour with lightly earthy, sweet and tangy notes. Flavour becomes stronger as plants age or experience stress.

Baby Leaf

Mild and Tender

Young foliage has the softest texture and is suited to mixed leafy dishes and quick cooking.

Young Shoots

Fresh and Succulent

Tender shoot tips can be harvested before stems become coarse.

Mature Leaves

Stronger Leafy Flavour

Larger foliage generally benefits from cooking and may require removal of firm stems.

Older Plants

Tougher and More Bitter

Plants left too long before harvesting can lose tenderness and develop coarse stems.

Stir-Fried

Quick-Cooked Green

Brief cooking softens the leaves while retaining colour and useful texture.

Soups and Curries

Soft Cooked Foliage

Leaves wilt into broths, sauces and spice-based dishes similarly to other tender greens.

How to Grow Amaranth in Australia

Red Garnet amaranth is a warm-season annual that grows best in full sun, warm soil and fertile free-draining ground.

Wait for Warm Soil

Amaranth establishes most reliably once the soil is warm and frost risk has passed.

Provide Sun or Light Shade

Full sun encourages strong colour and growth, while light afternoon shade can be useful in extreme heat.

Maintain Even Moisture

Regular watering supports tender leaves and reduces stress-related toughness.

Harvest While Young

Early and repeated picking provides better eating quality than allowing every plant to become fully mature.

Vegetable amaranth is a summer leafy crop. It complements rather than directly replaces the cool-season planting window of English spinach.

When to Plant Amaranth in Australia

Sow Red Garnet amaranth after frost risk has passed and the soil has warmed. A soil temperature of approximately 20°C or higher supports reliable establishment.

Climate Zone General Sowing Period Growing Notes
Cool October to January Plant after frost and use the warmest part of the year.
Temperate September to February Sow through spring and summer once the soil has warmed.
Subtropical September to March A long warm season supports repeated sowings and harvests.
Tropical Most of the year Grow during warm conditions while managing heavy rain and dry-season irrigation.
Arid September to February Provide reliable water, mulch and protection from severe drying winds.

These sowing periods are general guides. Local frost dates, elevation, rainfall, extreme heat and irrigation availability should also be considered.

When to Plant Amaranth in Australian States and Cities

Location General Planting Guide Key Considerations
Brisbane and South East Queensland September to March Warm spring and summer conditions support rapid growth; maintain airflow during humid weather.
Sydney and coastal New South Wales September to February Plant after the soil warms and provide moisture during hot dry periods.
Inland New South Wales October to January Wait until frost risk has passed and irrigate during extreme heat.
Melbourne and Victoria October to January Use the warmest frost-free part of the year for active leaf production.
Adelaide and South Australia September to February Mulch and water consistently through dry summer conditions.
Perth and south-west Western Australia September to February Spring planting allows establishment before the most severe summer heat.
Tasmania November to January Use a warm sheltered position and expect a shorter growing season.
Darwin and tropical northern Australia Extended warm-season window Manage rainfall, irrigation and fungal pressure according to the season.

How to Grow Amaranth from Seed

Amaranth can be direct-sown into garden beds and containers or raised in trays before transplanting.

  1. Choose a warm planting period.
    Wait until frost has passed and the soil has warmed.
  2. Prepare the soil.
    Use fertile, free-draining ground with a fine surface suitable for small seed.
  3. Sow shallowly.
    Plant the seeds approximately 5–10 mm deep and cover lightly.
  4. Water gently.
    Use a fine spray so the small seeds are not washed out of position.
  5. Maintain moisture.
    Keep the surface evenly moist during germination without leaving it waterlogged.
  6. Thin seedlings promptly.
    Adjust spacing according to whether the crop will be harvested as baby leaf or mature plants.
  7. Maintain steady growth.
    Water regularly and remove weeds competing with young plants.
  8. Harvest at the preferred stage.
    Cut baby leaves, pick tender shoots or allow selected plants to mature.
Successive sowing improves continuity. Plant smaller batches every few weeks rather than allowing the entire crop to become mature and coarse at the same time.

How Deep Should Amaranth Seeds Be Planted?

Plant Red Garnet amaranth seeds approximately 5–10 mm deep. The seed is small and should only be covered lightly.

Direct Sowing

Sow into a fine, weed-free bed once the soil has warmed.

  • Plant approximately 5–10 mm deep
  • Cover lightly with fine soil
  • Water with a gentle spray
  • Thin after seedlings establish

Seedling Trays

Use a clean, free-draining seed-raising medium.

  • Sow shallowly
  • Maintain warmth and moisture
  • Provide bright light after emergence
  • Transplant before seedlings become root-bound

How Long Do Amaranth Seeds Take to Germinate?

Red Garnet amaranth commonly germinates within approximately 7–14 days under warm conditions.

Soil Warmth

Warm soil supports faster and more uniform emergence.

Sowing Depth

Seed planted too deeply may struggle to reach the surface.

Moisture

The seedbed should remain evenly moist without becoming saturated.

Seedling Light

Provide bright light after emergence to produce sturdy growth and strong foliage colour.

Does Amaranth Need Light to Germinate?

Amaranth seed does not need to remain fully exposed on the soil surface, but it should be planted shallowly.

Cover the seed with only a thin layer of soil or seed-raising mix. After germination, provide strong light immediately.

Insufficient light can cause seedlings to:

  • Stretch and develop weak stems
  • Lean towards windows or openings
  • Produce pale foliage
  • Establish slowly after transplanting

How Far Apart Should Amaranth Be Planted?

Spacing depends on the intended harvest stage.

Harvest Goal Approximate Spacing General Result
Baby leaf Approximately 2–5 cm or densely sown rows High plant population for tender young-leaf cutting.
Small whole plants Approximately 10–20 cm Compact plants harvested before stems become coarse.
Mature leafy plants Approximately 30–45 cm Provides room for branching, repeated leaf picking and ornamental growth.
Plants retained for flowers or seed Approximately 45 cm or more Allows tall plants to develop broader canopies and flower heads.
Row spacing Approximately 45–60 cm Allows access for weeding, watering and repeated harvests.

How Tall Does Red Garnet Amaranth Grow?

Red Garnet amaranth can reach approximately 90–150 cm under favourable conditions when allowed to mature.

Plants harvested continually for young shoots may remain shorter. Mature height is influenced by:

  • Plant spacing
  • Soil fertility
  • Water availability
  • Temperature
  • Harvest frequency
  • Whether the plant is allowed to flower

Tall plants grown in exposed positions may benefit from wind protection or light support.

Can Amaranth Be Grown in Pots?

Yes. Red Garnet amaranth can be grown in containers for baby leaf, young plants or ornamental mature foliage.

Container Requirements

Choose the container according to the intended plant size.

  • Use troughs for densely sown baby leaf
  • Allow approximately 20–30 cm of soil depth
  • Use larger pots for mature individual plants
  • Provide unrestricted drainage holes

Container Management

Potted amaranth can dry rapidly during warm weather.

  • Position in full sun or bright partial shade
  • Use fertile, good-quality potting mix
  • Check moisture frequently
  • Thin crowded plants promptly

Can Amaranth Grow in Partial Shade?

Red Garnet amaranth grows best in full sun but can tolerate partial shade.

Strong light generally supports the most vivid red foliage and sturdy growth. In very hot climates, light afternoon shade may help maintain tenderness and reduce moisture stress.

Heavy shade can produce:

  • Weak elongated stems
  • Less intense red colour
  • Slower leaf production
  • Reduced plant strength

Watering and Feeding Vegetable Amaranth

Established amaranth can tolerate short dry periods, but consistent moisture produces better leafy-vegetable quality.

Water deeply enough to moisten the root zone. Avoid leaving the soil continually saturated.

Vegetable amaranth generally benefits from:

  • Fertile soil containing suitable organic matter
  • Balanced nutrition during active leaf growth
  • Regular watering during hot and dry weather
  • Mulch around widely spaced mature plants
  • Good drainage during heavy rainfall
Drought tolerance does not mean drought produces the best leaves. Water stress can result in smaller, tougher and more strongly flavoured foliage.

How Long Does Amaranth Take to Grow?

Harvest time depends on whether the crop is grown for baby leaves, young whole plants or mature foliage.

Harvest Stage Typical Period General Characteristics
Baby leaf Approximately 25–35 days Tender young foliage for quick cooking and mixed-leaf production.
Young whole plants Approximately 35–50 days Soft stems and leaves harvested before coarse mature growth develops.
Mature leaf harvest Approximately 50–60 days Larger plants providing repeated leaves and shoot tips.
Flowers and mature seed Longer than the vegetable harvest period Plants must remain in the ground to flower and complete seed development.

Growing time varies with temperature, soil fertility, water, plant spacing and the preferred harvest size.

How to Harvest Amaranth Leaves

Harvesting method depends on plant age and the desired product.

Harvest Method How It Works Best Suited To
Baby leaf cutting Cut young leaves above the growing point using clean equipment. Mixed leaves, quick cooking and dense plantings.
Whole young plants Harvest the complete plant while the stems remain tender. Traditional vegetable bunches and rapid crop turnover.
Shoot-tip harvesting Remove tender upper stems and leaves to encourage branching. Repeated household and market-garden harvests.
Individual leaf picking Remove selected young leaves while leaving enough foliage for growth. Small household harvests and ornamental plantings.

Harvest during the cooler part of the day where practical. Cool the foliage promptly and remove coarse, damaged or heavily soiled leaves.

Is Amaranth Cut-and-Come-Again?

Yes. Red Garnet can provide repeated shoot and leaf harvests when the plant remains healthy and sufficient growing points are retained.

For regrowth:

  • Cut above a healthy leaf node
  • Leave enough foliage for continued growth
  • Maintain consistent moisture after harvesting
  • Remove damaged or diseased leaves
  • Harvest again before new stems become coarse

Whole-plant harvesting provides faster crop turnover, while selective shoot harvesting can extend production from established plants.

Can Amaranth Be Grown as Baby Leaf?

Yes. Red Garnet is suitable for colourful baby-leaf production.

Baby-leaf crops are sown more densely than mature plants and harvested while the foliage is small and tender.

For baby leaf:

  • Prepare a fine, clean seedbed
  • Sow evenly at a relatively high density
  • Maintain consistent moisture
  • Provide strong light for good colour
  • Harvest before stems become coarse
  • Use clean equipment and appropriate post-harvest handling
Baby leaf is different from microgreens. Baby amaranth is grown until developed true leaves form, while microgreens are harvested at an earlier seedling stage.

Can Red Garnet Amaranth Be Grown as Microgreens?

Red Garnet amaranth can be used for microgreen production where the seed is untreated and suitable for edible crop use.

Amaranth microgreens are small and delicate and generally require:

  • A fine, level growing medium
  • Even seed distribution
  • Gentle watering
  • Warm germination conditions
  • Strong light after emergence
  • Careful harvesting because of their small stems

Always check the current product specifications before using any planting seed for microgreens. Chemically treated seed must never be used for edible sprouts, shoots or microgreens.

How to Prepare and Cook Amaranth Leaves

Use young leaves and tender shoot tips for the best texture.

  1. Sort the foliage.
    Remove coarse stems, damaged leaves and flower material where not required.
  2. Wash thoroughly.
    Rinse the leaves in clean water to remove soil and debris.
  3. Drain well.
    Remove excess surface water before frying or sautéing.
  4. Separate firm stems.
    Cook thicker stems before adding tender leaves.
  5. Cook briefly.
    The foliage wilts quickly and generally does not require prolonged cooking.

Ways to Use Vegetable Amaranth

Stir-Fried

Quick-Cooked Red Amaranth

Cook young leaves briefly with garlic, ginger, chilli, sesame or other vegetables.

Soups

Leafy Soup Green

Add chopped leaves and tender stems during the final stage of cooking.

Curries

Warm-Season Leaf Vegetable

Use the leaves in coconut, lentil, tomato or spice-based curries.

Steamed

Simple Cooked Greens

Steam young foliage lightly and season according to the preferred cuisine.

Egg Dishes

Omelettes and Frittatas

Wilt the leaves before combining them with eggs, herbs or cheese.

Mixed Greens

Colourful Leaf Blends

Combine young amaranth with other cooked Asian greens and leafy vegetables.

Can Amaranth Leaves Be Eaten Raw?

Very young leaves may be used raw in small amounts, but vegetable amaranth is generally better positioned as a cooked leafy green.

Cooking softens the foliage, reduces bulk and provides a more familiar preparation method across many Asian, African and Caribbean cuisines.

People with specific dietary or medical concerns should follow advice appropriate to their circumstances rather than relying on a seed-category page for individual nutrition guidance.

Can Amaranth Flowers and Seeds Be Eaten?

Recognised edible amaranth plants can produce edible flowers and mature seeds. However, crop purpose and seed handling matter.

Red Garnet is principally sold here as a vegetable-leaf variety. A planting retained for seed can produce mature seed, but:

  • Leaf varieties may not yield grain as efficiently as specialist grain amaranths
  • Seed must be fully mature and correctly cleaned
  • Planting seed should not be eaten merely because the crop is edible
  • Chemically treated seed must never be consumed
  • Saved seed may not remain true to type if plants cross-pollinate

How to Store Fresh Amaranth Leaves

Amaranth foliage is best used soon after harvesting.

For household storage:

  • Remove damaged or heavily soiled leaves
  • Cool the foliage promptly
  • Protect leaves from crushing
  • Store in a suitable produce bag or container
  • Control excess moisture and condensation
  • Wash shortly before use where practical
  • Discard slimy, mouldy or unpleasant-smelling foliage

Does Amaranth Self-Seed?

Amaranth can self-seed where mature flower heads are allowed to release viable seed.

To limit unwanted seedlings:

  • Harvest flower heads before seed is shed
  • Remove mature plants after the final vegetable harvest
  • Collect dropped seed where practical
  • Monitor the bed during the following warm season

To encourage voluntary seedlings, allow selected healthy plants to flower and mature. Seedlings may not remain completely true to the original variety where crossing has occurred.

Is Amaranth Annual or Perennial?

Red Garnet Amaranthus tricolor is generally grown as an annual.

The plant completes its growth, flowering and seed cycle within one season. It does not normally regrow indefinitely from the same crown like a long-lived perennial vegetable.

In warm frost-free climates, the growing period can be extended, and self-sown seedlings may create the appearance of continuing plants.

Common Amaranth Growing Problems

Poor Germination

Cold soil, deep sowing, drying seedbeds and excessive water can reduce emergence.

Pale or Weak Seedlings

Insufficient light, crowding and excessive moisture can produce stretched plants.

Tough Leaves and Stems

Plant age, drought and delayed harvesting can reduce tenderness.

Chewed Foliage

Caterpillars, beetles, slugs, snails and other pests may damage young leaves.

Yellow Leaves

Old foliage, waterlogging, drought, root stress or nutrient imbalance can cause yellowing.

Plants Flowering Early

Plant maturity, stress and seasonal conditions can shorten the leafy harvest period.

What to Plant with Amaranth

Amaranth can share warm-season gardens with crops that have similar sunlight and watering requirements.

Potential neighbouring crops include:

  • Eggplant
  • Okra
  • Chilli and capsicum
  • Warm-season beans
  • Ceylon spinach
  • Basil and other summer herbs
  • Spring onions positioned around bed edges
  • Flowers that support beneficial insects

Allow adequate space so mature amaranth plants do not heavily shade smaller crops.

Packet and Larger-Quantity Amaranth Seeds

Home and Small-Scale Growers

Smaller seed quantities suit household gardens, raised beds, pots and growers trialling amaranth for the first time.

  • Grow baby leaves or mature plants
  • Add red colour to edible gardens
  • Use successive warm-season sowings
  • Trial container and garden-bed production

Market Gardens and Commercial Growers

Larger quantities can support repeated leafy-green, baby-leaf and specialty vegetable plantings.

  • Suitable for scheduled warm-season sowings
  • Useful for Asian vegetable and specialty leafy-green markets
  • Can be harvested as young plants or tender shoots
  • Compare leaf yield, colour and harvest labour
Compare value by saleable leaf production. Germination, plant density, harvest stage, regrowth, stem tenderness, trimming labour and usable leaf yield all influence the real production cost.

Important Considerations for Commercial Growers

Commercial vegetable-amaranth production requires a defined harvest stage, customer specification and warm-season crop schedule.

Leaf Colour

Consistent red foliage improves bunch, baby-leaf and specialty market presentation.

Harvest Stage

Baby leaf, whole young plants and repeated shoot harvests require different sowing densities.

Stem Tenderness

Delayed harvesting increases trimming requirements and reduces the proportion of saleable product.

Crop Uniformity

Even germination and plant density support consistent harvest timing and bunch size.

Post-Harvest Handling

Cool foliage promptly and protect delicate leaves from crushing and excess moisture.

Customer Terminology

Identify the crop clearly as Red Garnet vegetable amaranth, Chinese spinach or leaf amaranth according to the target market.

Conduct local production trials before large sowings. Germination, colour, plant height, tenderness, regrowth and saleable yield can vary with temperature, density, irrigation, soil and harvest timing.
