Ctenanthe : Greenhouse Plants
T – tropical, minimum of 18°C (65°F)
Cultivation of these is similar to that of their close relation Calathea. They will not like cold temperatures or fluctuations and specifically dislike having to sit in wet boggy, particularly if it is colder than they like. A peat-based compost and warm humid conditions will be rewarded by a display of very attractive foliage. Ctenanthe lubbersiana has 23-cm (9-in) long leaves in many different shades of green. C. oppenheimiana ‘Tricolor’ has longer leaves which are cream and green in bold areas with a pinky-purple underside. Watch out for red spider mite, which like to attack these plants especially under dry conditions. When potting, usually in early summer, offsets can be taken from the parent plants. Alternatively shoot can be taken.
