Australian Grown Black Sunflower Microgreen Seeds
Botanical Name: Helianthus annuus
These black sunflower seeds are grown in Australia and ideal for growing microgreens. The young shoots have a nutty taste and crisp stems, making them great in salads, wraps, smoothies, or as a fresh topping. They’re easy to grow and full of nutrients.
These seeds have been picked especially for sprouting. With basic care, you’ll grow strong green shoots with great flavour.
Nutritional Content
Sunflower microgreens are not just tasty—they’re also full of nutrients:
- Protein: 20–25%
- Vitamins: A, B, C, D, and E
- Minerals: Calcium, iron, and essential amino acids
How to Grow at Home
Sunflower shoots are a bit trickier to grow than other microgreens because they can attract mould. But if you keep things clean and follow the steps, you’ll get a healthy crop.
Difficulty
Moderate. These seeds need good airflow, spacing, and hygiene. Try a small batch first to get a feel for the process.
Growing Medium
Use soil or coir peat for best results. Hydroponics isn’t ideal because of the roots and mould risk.
Soaking Instructions
Soak 1 to 1½ cups of seeds (for a 30 x 35 cm tray) in cool water for 8–12 hours. Use a plate or lid to keep them underwater. Soaking helps remove the seed hull and kickstarts sprouting.
Pre-Sprouting
After soaking, leave the seeds to sprout for one day in a jar, tray, or hemp bag. Keep them damp, not wet. This helps them grow evenly and reduces mould.
Ideal Temperatures
Germination works best at 20–25°C. Growth slows down in cold weather, so try a heat mat or a warm, sunny spot in winter.
Tray Method
- Add 2–3 cm of soil or coir peat to the tray and flatten it.
- Lightly water the surface.
- Spread seeds evenly without piling them up.
- Press them into the surface and mist lightly.
Blackout Stage
Cover the tray with another tray or lid and keep it in a dark spot with airflow. Water once or twice a day. In 4–5 days, the shoots will start to lift the lid—this means it’s time to uncover them.
Light & Harvest
Move the tray into sunlight or under a grow light. Mist twice daily, but don’t overwater. Harvest in 7–14 days when the shoots are 8–12 cm tall. Cut just above the soil with clean scissors.
Tips for Success
- Clean trays and tools after each use.
- Use a fan or grow in a well-ventilated space.
- Keep trays somewhere bright and warm.
- Rinse harvested shoots and store in the fridge straight away.
