Amaranthus
Common name: Amaranth
Amaranths are a diverse and dramatic group of annuals and short-lived perennials, grown for their vibrant foliage or eye-catching, tassel-like flowers. Some species are edible and are grown as leafy greens in the UK, or for grain in warm climates.
Looks
Amaranths come in a wide range of forms, but most have long, drooping or tall, upright flower spikes, in deep crimson, burgundy, lime green or gold. The foliage can be equally striking, with broad, green, red or purple leaves that give a lush, tropical appearance. They flower from midsummer to early autumn, with some varieties reaching over 1.5m tall.
Likes
Amaranths prefer full sun and well-drained soil, in a warm, sheltered site. While not fussy about soil type, adding organic matter will promote strong growth. In the vegetable garden, amaranths grown for grain or leaves benefit from consistent moisture and good air circulation.
Dislikes
They dislike cold, wet soils and will not survive frost. They will also struggle in shade, showing weak growth and poor flowering and/or foliage colour.
Did you know?
Grain amaranth has been cultivated for thousands of years in the Americas and was a staple food for the Aztec peoples. Both leaves and seeds of some species are still enjoyed today.
