Buddleja davidii 'Nanho Blue'

Plant details

Known as the butterfly bush, Buddleja davidii bears conical, nectar-rich flowers, which attract butterflies and bees in late summer. Flowers come in a variety of colours including purple, blue, pink and white. Plants are easy to grow and thrive in almost any situation.

Buddleja davidii 'Nanho Blue' has beautiful purple-red flowers. For best results grow in well-drained soil in full sun. Left unpruned, Buddleja davidii 'Nanho Blue' can become leggy so prune hard back every year. To encourage later flowering (which benefits garden butterflies such as the small tortoiseshell), cut plants back to the base in May.
