Amaranthus ‘Molten Fire’ is a dazzling ornamental variety that lives up to its name, with brilliant crimson, orange, and bronze foliage that glows in the garden like living flame. Native to Central and South America, amaranthus has been cultivated for centuries both as a decorative and edible plant. ‘Molten Fire’ was bred for its stunning colour and dramatic garden impact, making it a standout in any flower or foliage display.

Although grown primarily for its vivid colour, Amaranthus is edible and highly nutritious. The young leaves can be used like spinach and are rich in iron, calcium, magnesium, vitamin C, and antioxidants. The seeds of amaranthus species are also known for their high protein content, though ornamental types like ‘Molten Fire’ are usually enjoyed for their beauty rather than harvest.

This variety is perfect for adding warmth and contrast to flower borders, garden beds, and containers. Its vibrant foliage makes an eye-catching background for flowering plants or a bold feature on its own. The leaves can also be harvested when young for use in salads or stir-fries, adding a splash of colour to the plate.

Amaranthus ‘Molten Fire’ is a fast-growing annual that can reach up to 90 cm to 1.2 metres tall. It thrives in full sun and well-drained soil and is tolerant of heat and dry conditions once established. The more sun it receives, the deeper and more vibrant the foliage colour becomes. It is an easy-care plant that adds dramatic colour to summer and autumn gardens.

How to Grow From Seed:

Sow seeds directly into the garden in late spring to early summer, once the soil is warm and frost-free. Scatter the seeds thinly over the soil surface and cover very lightly with fine soil or sand.

Keep moist until germination, which usually takes 7–14 days.

Thin seedlings to about 30–40 cm apart once established. Amaranthus grows best in full sun with moderate watering.

Avoid over-fertilising, as too much nitrogen can reduce leaf colour intensity. Regular picking of young leaves will encourage new growth and extend the life of the plant.
