Description
Amaranthus –
There are about 60 species of erect spreading or prostrate annuals or short-lived perennials, used as houseplants, in this genus. Grown as ornamentals, leaf vegetables, and grain crops but some are regarded as a weed. Found in wastelands and in temperature and tropical regions worldwide. They have alternate often-colorful leaves. They bear large upright or pendent catkin, drooping tassel like cymes of numerous densely packed small red or green flowers from early summer to early autumn followed by colored seed heads.
Indoors grow in soil based potting mix in full light, water freely throughout summer and provide high humidity. Where able to grow outside, grow in a sunny dry position and protect from strong winds, in fertile well drained, manure or humus rich site. Prune when young to thicken growth.
