Care guide
In Cyprus
Alternanthera is a tropical perennial that is often grown as a seasonal bedding plant in cooler climates. Its leaf colour is strongest in full sun, although in very hot summers strong sun can bleach the foliage of some varieties. It needs rich soil that stays consistently moist but drains well, so in Cyprus it belongs in irrigated beds, watered according to soil moisture and weather. It is frost-sensitive: plant it in spring once the risk of frost has passed, unless it will be grown under protection. The first frost usually ends its ornamental season.
Uses in gardens and projects
A low, spreading plant grown for its coloured foliage, it is used for edging, the front of beds, massed planting and containers in courtyards and on terraces. It grows fast, and pinching back the shoot tips keeps it bushier. It makes a strong contrast next to green-leaved plants. Its flowers are small and of little ornamental value; it is grown for the leaves.
