Streptosolen : Greenhouse Plants
C – cool, minimum of 7°C (45°F) / W – warm, minimum of 13°C (55°F)
Streptosolen jamesonii is just about describable as a climber although it does not support itself and requires staking or tying in. It produces many orange bell-shaped flowers in summer which made it popular for tropical bedding outside. The main disadvantage as a greenhouse plant, is that whitefly are attracted to it and are a constant pest. Cuttings root very easily during summer to ensure successions of fresh plants. Prune all the side shoots back to within a node of the main stems after flowering. Burn the unwanted material if it is harbouring whitefly eggs. Seed should be sown just under the surface of peat-basedat 13-15°C (55-60°F) in spring.
