Nerium: Greenhouse Plants
C – cool, minimum of 7°C (45°F) / W – warm, minimum of 13°C (55°F)
Nerium oleander from Mediterranean regions, usually referred to simply as Oleander, is a very reliable and showy flower for the greenhouse, which if grown in tubs or pots can also be moved on to the patio during hot dry weather in summer; I would put it back inside during times of wind and rain as these will spoil the flowers. As there are different forms with different coloured flowers quite a collection of dark and pale pink, white, creamy-yellow, doubles and a variegated form with lovely creamy stripes on the leaf can be grown. I give my plants plenty of water and liquid feed during spring and early summer while they are building themselves up to flower from about June onwards. After flowering they can be pruned back. Cuttings are easily rooted from shoots taken any time during spring and summer. Seed can also be sown. Be careful with the plant as all parts of it are poisonous. Unfortunately, though, they are not poisonous to mealy bug which will make a meal of them if not controlled.
