Leafy green seed buying guide

Choose the Right Leafy Green Seeds

Leafy greens are vegetables grown primarily for their edible leaves, stems and young shoots. They range from tender salad crops and mild spinach varieties to robust silverbeet, kale, mustard greens and other vegetables commonly used in cooked dishes.

Seedmart supplies leafy green seeds for home gardeners, market gardeners, restaurants and commercial growers throughout Australia. The range includes quick-growing baby leaf crops, productive cut-and-come-again vegetables and mature bunching varieties available in packet and bulk quantities.

The best leafy green seed will depend on your climate, planting season, available space, preferred flavour and whether the crop will be harvested as baby leaf or allowed to reach maturity.

Why Grow Leafy Greens?

Fast Harvests

Many leafy vegetables can be harvested young, making them suitable for gardeners and growers seeking relatively short crop cycles.

Repeated Picking

Silverbeet, kale, rocket and several other varieties can provide multiple harvests when outer leaves are picked carefully.

Suitable for Small Spaces

Many leafy greens grow well in raised beds and containers where sufficient light, soil depth and moisture are provided.

Flavour and Colour

Choose from mild, sweet, peppery, mustard-like, earthy and pleasantly bitter varieties in green, red and purple tones.

Versatile Harvests

Use freshly harvested leaves in salads, sandwiches, stir-fries, soups, pasta, curries and other cooked dishes.

Packet and Bulk Seed

Select smaller packs for home growing or larger quantities for frequent sowing, market gardens and commercial production.

Baby Leaf and Mature Leafy Greens

The same vegetable may be harvested at different stages depending on the preferred flavour, texture, yield and market.

Harvest Type Suitable Examples General Characteristics
Baby leaf Spinach, rocket, mizuna, mustard greens, kale and salad mixes Harvested young for tender leaves, compact size and relatively short production cycles.
Cut-and-come-again Rocket, mizuna, silverbeet and selected lettuce mixes Leaves are cut above the growing point so the plant can produce additional growth.
Mature bunching Silverbeet, kale, spinach, broccoli raab and edible chrysanthemum Plants are allowed to develop larger leaves and stems before being picked or cut.
Individual outer leaves Silverbeet, perpetual spinach and kale Outer leaves are harvested progressively while younger central growth remains on the plant.
Mixed salad leaves Mesclun, mixed lettuce, rocket, mizuna and mustard greens Different varieties may be combined to provide contrasting colours, flavours and leaf shapes.
Harvest stage affects flavour and texture. Young leaves are generally smaller and more tender, while mature leaves provide greater volume and often develop a stronger flavour.

Cool-Season and Warm-Season Leafy Greens

Many leafy vegetables perform best during mild conditions, but the category also includes crops suited to warmer periods.

Growing Group Examples General Growing Conditions
Cool-season tender greens Spinach, corn salad and lettuce mixes Generally produce their best leaf quality during cool to mild conditions.
Cool-season brassica greens Kale, mizuna, mustard greens, broccoli raab and spigariello Prefer mild growing weather, although tolerance varies between varieties.
Broad-season productive greens Silverbeet and perpetual spinach Adaptable crops that can remain productive across an extended period when local conditions are suitable.
Warm-season leafy crops Amaranth Prefers warm soil and air temperatures and can provide leafy harvests during hotter weather.
Specialty seasonal greens Edible chrysanthemum and endive Planting time should be matched carefully to local temperatures and the variety’s growing requirements.

Planting times vary across Australia’s tropical, subtropical, temperate and cool-climate regions. Check the individual product description for more specific sowing information.

Leafy Green Seeds for Australian Climates

Temperate and Cool Regions

Spinach, kale, rocket, mizuna, mustard greens, endive and corn salad generally perform well during the milder parts of the year.

  • Plant cool-season crops during locally suitable autumn, winter or spring conditions
  • Use successive sowings to extend the harvest period
  • Protect young plants from severe frost where required
  • Maintain steady moisture as temperatures begin to rise

Subtropical and Tropical Regions

Many cool-season leafy vegetables are best planted during the mildest part of the year. Warm-season amaranth can be used when conditions become too hot for spinach and other cool-loving greens.

  • Grow spinach and brassica greens during cooler local conditions
  • Select heat-tolerant crops for warm-season production
  • Use mulch to reduce moisture loss and moderate soil temperature
  • Provide afternoon protection where excessive heat damages leaf quality
Hot weather can cause leafy vegetables to bolt. Spinach, rocket, mizuna, mustard greens, lettuce and several other crops may flower prematurely when exposed to heat, long days, water stress or unsuitable planting conditions.

Popular Types of Leafy Greens

Spinach

Spinach produces tender leaves suited to salads, cooking and baby leaf production. It generally performs best in cool to mild conditions.

Silverbeet and Chard

Silverbeet is a productive leafy vegetable with substantial leaves and edible stems. Green and coloured-stemmed varieties are available.

Kale

Kale develops robust leaves that may be picked young or allowed to mature. Varieties differ in leaf shape, colour and texture.

Rocket

Cultivated rocket grows quickly and produces broad peppery leaves, while wild rocket generally develops narrower leaves and a stronger flavour.

Mustard Greens

Mustard greens are grown for colourful leaves and distinctive spicy flavour. Young leaves may be used fresh, while mature leaves are often cooked.

Mizuna

Mizuna produces finely divided leaves with a mild mustard flavour. It is suitable for salads, stir-fries and repeated young-leaf harvesting.

Endive and Corn Salad

Endive provides crisp leaves with a pleasantly bitter character, while corn salad produces tender rosettes with a mild flavour.

Salad Green Mixes

Mesclun and mixed lettuce blends combine several leaf forms, colours and flavours in a single sowing.

Leafy Greens for Containers and Raised Beds

Many leafy vegetables are well suited to compact gardens because they can be planted more closely than large fruiting crops and harvested before reaching full maturity.

Containers and Courtyards

Spinach, rocket, mizuna, mustard greens, corn salad and mixed salad leaves can be grown in containers with sufficient drainage and suitable potting media.

  • Choose containers with adequate drainage holes
  • Use sufficient soil depth for healthy root development
  • Water regularly because containers dry faster than garden beds
  • Avoid overcrowding, which can reduce airflow and leaf quality

Raised Beds and Garden Plots

Raised beds provide room for larger silverbeet, kale and mature spinach plants while also supporting successive rows of baby leaf vegetables.

  • Prepare fertile, well-drained soil before sowing
  • Separate mature plants from densely sown baby leaf crops
  • Use crop rotation where leafy brassicas are grown regularly
  • Protect seedlings from snails, slugs and caterpillars

Packet and Bulk Leafy Green Seeds

Home and Small-Scale Growers

Smaller seed quantities are suitable for household gardens, raised beds, containers and growers trialling new varieties.

  • Grow several varieties for different seasons and uses
  • Trial unfamiliar greens before planting larger areas
  • Create mixed salad plantings with contrasting leaves
  • Suitable for garden beds, balconies and courtyard gardens

Market Gardens and Commercial Growers

Bulk leafy green seed can be more economical for growers producing repeated crops, bunches, mixed leaves or baby leaf vegetables.

  • Suitable for repeated and scheduled sowings
  • Larger quantities available across selected core varieties
  • Useful for market gardens, restaurants and food producers
  • Compare sowing rate, harvest stage and usable yield
Compare the cost per growing area, not only the seed price. Seed size, germination, planting density, crop duration and usable harvested yield all influence the actual cost of producing leafy vegetables.

Important Considerations for Commercial Growers

Commercial leafy green production requires more than choosing the lowest-cost seed. Crop uniformity, seasonal suitability, harvest method, shelf life and customer demand all affect the value of the finished crop.

Germination and Uniformity

Even emergence helps produce consistent baby leaf crops and makes mature bunching vegetables easier to manage.

Harvest Method

Consider whether the crop will be cut mechanically, hand-picked as outer leaves, sold in bunches or harvested as a mixed baby leaf product.

Seasonal Performance

A variety that performs well in winter may bolt rapidly or develop poor leaf quality during warm conditions.

Market Demand

Select varieties according to the requirements of local households, grocers, restaurants, farmers markets and other buyers.

Seed availability can vary. Some leafy green varieties are seasonal, imported in limited quantities or unavailable for extended periods. Commercial growers should trial alternatives and avoid relying entirely on one specialty variety.

General Leafy Green Growing Method

  1. Choose a variety suited to the season.
    Match cool-season and warm-season leafy vegetables to your local climate and expected growing conditions.
  2. Prepare fertile, well-drained soil.
    Remove weeds and compaction before sowing. Incorporate suitable organic matter where required.
  3. Sow at the recommended depth.
    Most leafy green seed is relatively small and should not be buried too deeply. Follow the instructions supplied for the individual variety.
  4. Thin seedlings where required.
    Provide sufficient spacing for mature plants, or maintain a closer planting density when producing baby leaf crops.
  5. Water consistently.
    Keep the soil evenly moist without leaving it waterlogged. Irregular watering can reduce leaf quality and encourage stress.
  6. Provide adequate light and airflow.
    Avoid excessive crowding and manage shade according to the crop, season and local climate.
  7. Monitor pests regularly.
    Protect young plants from slugs, snails, aphids, leaf miners, flea beetles and caterpillars where these are present.
  8. Harvest at the preferred stage.
    Cut baby leaves while tender, pick mature outer leaves progressively or harvest complete plants according to the variety and intended use.
Sowing rates and plant spacing vary substantially. Closely sown baby leaf crops require a different production method from silverbeet, kale and other leafy vegetables grown to full size.

Frequently Asked Questions

Which leafy greens are easiest to grow?

Silverbeet, kale, rocket and mizuna are useful starting points when planted during suitable conditions. The easiest variety will depend on your local climate, season and available growing space.

Which leafy greens grow the fastest?

Rocket, mizuna, mustard greens and many mixed salad leaves can produce relatively fast young-leaf harvests. Crops grown to full size require more time than those harvested as baby leaves.

When should leafy green seeds be planted?

Most spinach, kale, rocket, mizuna, mustard greens, endive and corn salad varieties prefer cool to mild growing conditions. Warm-season amaranth should be planted when temperatures are consistently warm. Check the individual product page for regional guidance.

Can leafy greens be grown in pots?

Yes. Many leafy greens grow well in pots, troughs and raised planters. Use a suitable growing medium, provide adequate drainage and select a container deep enough for the mature size of the crop.

What does cut-and-come-again mean?

Cut-and-come-again harvesting involves removing leaves above the central growing point so the plant can produce another flush of growth. Rocket, mizuna and some salad mixes are commonly grown using this method.

What is the difference between spinach and silverbeet?

True spinach and silverbeet are different crops. Spinach generally produces smaller, softer leaves and prefers cooler conditions. Silverbeet develops larger leaves with substantial edible stems and often remains productive over a longer period.

Can mature leafy greens be harvested more than once?

Many can. Silverbeet, perpetual spinach and kale may be harvested by removing the oldest outer leaves while leaving the central growth intact. Harvesting method varies by crop.

How do I stop leafy greens from bolting?

Plant cool-season varieties during suitable mild weather, maintain steady moisture and avoid unnecessary root disturbance. Heat, long days, drought stress and overcrowding can encourage premature flowering.

Can leafy greens be grown indoors?

Leafy greens can be grown indoors where they receive sufficient light, airflow and growing space. Indoor conditions must still support healthy root growth and prevent excessive moisture around the leaves.

How much leafy green seed do I need?

The quantity depends on seed size, growing area, planting density and harvest stage. Baby leaf crops are generally sown more densely than vegetables grown to full maturity. Check each product page and conduct a small trial before large commercial sowings.

Can beetroot leaves be grown as leafy greens?

Yes. Young beetroot leaves can be harvested for mixed leaf production, although removing too many leaves from plants intended for root production may reduce root development.

Are all leafy green seeds open-pollinated and untreated?

Product specifications can vary between varieties and seed lots. Review the individual product page for information about variety type, seed treatment, germination and other relevant specifications before ordering.
