Description
Amaranth Garnet Red is a long-time favourite with chefs, prized for its exceptional colour and versatility in the kitchen. It is widely regarded as the most intensely coloured amaranth, with its rich red tones becoming even more vivid in very warm conditions. As the heat builds, so does its visual impact, making it as striking in the garden as it is on the plate.
The leaves are particularly beautiful, with a dark grey-green surface flushed with red and a deeper crimson hue underneath. The veins stand out clearly in red, giving each leaf a dramatic, almost painted appearance. Warm weather brings out the strongest colouring, so summer-grown plants tend to be the most vibrant. Young leaves are tender, highly nutritious, and carry a delicate and slightly sweet flavour, similar to spinach that makes them especially appealing for fresh eating.
Highly valued in Asian cuisine, Amaranth Garnet Red is a wonderfully flexible plant. The leaves can be harvested young as baby leaf for salads or used as a colourful garnish, or they can be left to mature and added to soups and steamed dishes. When cooked, the soft leaves behave much like spinach, wilting down beautifully and developing a silky texture that makes them easy to incorporate into a wide range of meals. Beyond the leaves, mature plants can also be allowed to set seed, which can then be harvested and used as a nutritious grain.
One of amaranthโs great strengths is its reliability in hot weather. It is easy to grow and tolerant of a wide range of conditions, thriving during the height of summer when crops like spinach often struggle or fail altogether. This makes it an invaluable leafy green for warm climates and summer gardens.
Amaranth Garnet Red is not just productive, it is also highly ornamental. Its long-lasting blooms rise above the foliage on tall, straight stems, forming spear-like plumes of deep crimson. These dramatic flower heads make it a standout choice for beds, borders, mass plantings, and cottage gardens, where it can be grown purely for its visual appeal or as a productive edible ornamental.

๐ฑ Sowing: In Trays vs. Direct in the Ground
๐ฟ Starting in Trays
For an early start or if you’re dealing with cooler spring soil, starting in trays is a smart move.
- Use seed-raising mix in shallow trays.
- Sow thinly, covering with just a sprinkle of mix or vermiculiteโlight aids germination, so donโt bury them deep.
- Keep moist and warm (around 20โ25ยฐC soil temperature). Germination is fastโ5โ10 days.
Tray-sown seedlings transplant easily. Just be gentle with the roots, as amaranth doesnโt love root disturbance once it gets bigger.
๐ฟ Direct Sowing
In warm climates or later in the season, you can sow directly.
- Rake your bed smooth, water well, and scatter seeds thinly.
- Firm down gentlyโdon’t bury them deeply.
- Thin out once seedlings are 5โ10 cm tall, spacing to about 30 cm apart for leaf harvest, or 45โ60 cm for flowering types.
๐ง Pre-treatment Required?
None neededโamaranth germinates readily without pre-soaking or scarification. Just sow and keep consistently moist during germination.
๐ Soil & Position
Amaranth thrives in full sun, loving long, hot days. The ideal soil is:
- Well-drained, even slightly sandy
- Rich in organic matter, but not overly nitrogen-heavy (too much and you’ll get lush leaves but fewer flowers)
- pH range of 6.0โ7.5
Add compost or aged manure before planting. Itโs a good idea to mulch around plants once theyโre up and growing, to retain moisture and suppress weeds.
๐ฟ Care & Maintenance
Amaranth is drought-tolerant once established, but performs better with consistent moistureโespecially if you’re harvesting tender leaves. Hereโs what to keep in mind:
- Watering: Deeply 1โ2 times a week; donโt let it dry out when young.
- Feeding: A liquid feed every fortnight helps with leaf production. Seaweed or compost tea works beautifully.
- Support: Tall flowering varieties may need staking in windy spots.
- Weeding: Keep the area weed-free early on to avoid competition.
Keep harvesting the leaves regularly and deadhead flowers if you donโt want it going to seed too early.
๐ธ Companion Planting Guide
Amaranth is a great neighbour in the garden:
| Companion | Benefits |
|---|---|
| Corn | Amaranth provides groundcover and corn offers shade in extreme heat. |
| Tomatoes | Helps with soil coverage and pest confusion. |
| Basil | Attracts pollinators and repels aphids. |
| Nasturtiums | Acts as a trap crop for pests like aphids and flea beetles. |
| Beans | Fix nitrogen and support leafy growth. |
Avoid planting with spinach or beetrootโtheyโre from the same family and may attract the same pests.
โ๏ธ Harvesting
You can start harvesting baby leaves as soon as the plant is around 20 cm tallโjust a few from each plant to keep it growing.
- Leaf Harvest: Pinch out the top leaves regularly for the most tender growth.
- Flower Harvest: Tall, plumy flower spikes are ready for fresh arrangements or drying once fully formedโusually 8โ12 weeks from sowing, depending on the variety.
If growing for seed, let the flowers mature and dry on the plant.
๐ Common Issues & Fixes
Hereโs a quick troubleshooting table for common problems:
| Issue | Symptoms | Fix |
|---|---|---|
| Aphids | Sticky leaves, curling tips | Spray with soapy water, encourage ladybirds |
| Flea beetles | Tiny holes in leaves | Use floating row covers early on |
| Downy mildew | Yellow patches under leaves | Improve air circulation, avoid overhead watering |
| Root rot | Wilting despite moist soil | Ensure soil is well-drained, avoid waterlogging |
| Bolting (early flowering) | Rapid tall growth | Stress responseโensure even watering and donโt overfeed |
๐พ Seed Saving Guide
Saving amaranth seed is easy and satisfyingโjust be sure youโre growing an open-pollinated or heirloom variety.
- Let flower heads fully dry on the plant. Theyโll turn brown and feel crisp to the touch.
- Cut and dry further in a warm, dry place on paper or mesh.
- Rub the seed heads gently to release tiny seeds.
- Winnow to remove chaff (a small fan or breeze helps separate the seed).
- Store in a labelled paper envelope in a cool, dry spot. Viable for 3โ5 years when kept dry.
Amaranth is wind and insect-pollinated, so if you’re growing multiple varieties, give them at least 500 m spacing to reduce cross-pollination.
๐ผ Final Thoughts
Amaranth really earns its place in any Australian gardenโespecially if you love colour and kitchen productivity. It grows quickly, handles heat like a champion, and rewards you with striking flower spikes, nutritious greens, and even edible seeds if you let them mature.
Whether youโre tucking some in as a leafy green for summer stir-fries, or growing the bold flowering types as a backyard showstopper, amaranth is both forgiving and generous.
So go aheadโscatter a few seeds, and let this ancient plant bring a splash of drama and utility to your garden beds.
