Lonicera : Greenhouse Plants
C – cool, minimum of 7°C (45°F)
hildebrandiana is one of the only two tender honeysuckles usually found in greenhouse collections both of which are evergreen and flower in summer. This is the Giant Honeysuckle from Burma, Siam and China. It is a plant on a rather large scale and needs a fair amount of head room to do it justice. Each flower is up to 15 cm (6 in) long and, as they begin white and fade to orange, it gives the appearance of having flowers of different colours on the same plant. They are only faintly scented. L. sempervirens from southern USA is the Trumpet Honeysuckle and has unscented flowers which are red outside and orange-yellow inside the tube. Propagation is by 8-10-cm (3-4-in) long taken in July or August and rooted at 15°C (60°F).
