The Buddleja genus includes about hundred species of flowering plants endemic to Asia, Africa, and America. The flowers are generally rich in nectar and often strongly honey-scented. Therefor attracting butterflies, bees and moths. Buddleja davidii is one of the most used cultivates in gardens it descends from central China. It is a great coloniser of dry open ground since it self-sows. Buddleja davidii may become invasive in some regions of USA and UK. It is banned in certain areas and other species are recommended to use. There are also some cultivars with sterile seeds to choose from. Due to its likeness to spread it also inhabited urban bomb sites in the aftermath of World War II. This gave it the less flattering nickname ‘the bombsite plant’.
Description: Buddleja davidii is a vigorous shrub with an arching habit. It is frost sensitive and often the old plant parts (last year´s growth) are killed during the winter in temperate areas like Sweden. This is not a problem if the roots survive since it is fast growing and younger wood is more floriferous. There is a wide range of varieties where ‘Black Night’, ‘Nahno Blue’ (small variety), ‘White Profusion’ are some of the more common.
How to grow: Buddleja davidii prefers warm, nutritious soil rich in compost or mould with good drainage. Dry or heavy soils does not suit it. Place it in a sunny and protected spot in the garden. To encourage new growth the shrub is usually hard-pruned in spring once frosts have finished. To avoid spreading of seeds and prolong the blossom over-bloomed flower panicles are pruned. In areas with cold frosty winters you should cover the basal parts with soil, leaves or hay to protect the roots.
