Kohleria: Greenhouse Plants
W – warm, minimum of 13°C (55°F)
These are attractive hairy-leaved plants which grow from underground running rhizomes. They have a tendency to be straggly and should be staked at a young stage to prevent this. Kohleria eriantha from Colombia will bear its red tubular flowers at the top of 60-120-cm (2-4-ft) stems at virtually any time of the year. It is best to keep rooting fresh8 cm (3 in) long so as to be able to throw out larger straggly specimens. Alternatively, they can be cut right back after the flowers and fresh new furry growth will soon appear. Propagation can also be by potting up pieces of rhizome in the spring. K. digitaliflora should be treated in the same way. It certainly lives up to its name in that the flowers are like foxgloves. The flower tubes are a pinky-purple but the lobes are an amazing canned pea green colour with pink dots. There are various hybrids offered for sale.
