Very tolerant of alkaline soils, atmospheric pollution and maritime exposure[200]. Grows best on dry soils of low fertility, where it can seed itself freely[182]. Plants are hardy to about -15°c[184], they resprout from the base if cut back by cold weather[200]. A very ornamental plant[1], it hybridizes freely with other members of this genus. Polymorphic, there are many named varieties, developed for their ornamental value[182]. The flowers emit a musk-like fragrance like heather honey[245].

Propagation

Seed - cold stratify for 4 weeks at 4°c[138] and surface sow the seed in February/March in a greenhouse[78, 113]. Germination usually takes place within 3 - 4 weeks at 21°c[138]. When large enough to handle, prick the seedlings out into individual pots and grow them on in the greenhouse for at least their first winter, planting them out into their permanent positions in late spring or early summer, after the last expected frosts. Seedlings are inclined to damp off and so should be watered with care and kept well-ventilated[78]. Cuttings of half-ripe wood, July/August in a frame[11, 113]. Use short side-shoots[78]. Very high percentage[113]. Cuttings of mature wood of the current season's growth, 15 - 20cm long, October/November in a frame[200].

Butterfly Bush Uses for butterfly bush and how to grow it.

Other use: Buddleia davidii 'Black Knight' - I have one that produces a great crop of long straight branches, which, when harvested in late Autumn, before the frosts start, stripped of leaves and small branchlets, can be tied together in bunches and stored in a cool, dry, dark environment to make excellent plant canes/supports for the following year.

I hope someone can tell me whether Buddleia branches, the thicker, overgrown and woody ones, can be used for kindling and larger pieces of firewood. If you have found this to be a usable wood for emergency use especially, please let me know at bearhaven@suddenlink.net. Thanks, Jorie.

My general interest and research is into wild foods and whilst researching and writing recipes for my wild food e-book, I made syrup this year from Buddleia davidii flowers. It was extremely delicious in its own right without mention of its medicinal qualities. It has, apparently, been used for centuries in Chinese medicine for the treatment of bronchial complaints and is known for its sedative and calming influences upon the system. Through my personal use of it I found it to be of a gently soporiphic nature and definitely excellent for sleep and rest. No harmful side effects noted or experienced when taking one teaspoon up to one dessertspoonful at any given time, although I would not recommend taking it if needing to operate machinery, due to its sedative qualities. One could mix the syrup with fizzy water and ice for a refreshingly different non alcoholic evening drink whilst watching the sun go down!
