BUDDLEJA
Commonly known as Buddleia, Butterfly bush, Summer lilac
The Buddleja, Buddleia or Buddlea, named after English rector Rev. Adam Buddle is pronounced without the "j".
Genus of about 100 species of evergreen, semi-evergreen and deciduous shrubs, sometimes trees and climbers and a few herbaceous perennials.
They originate from riversides, rocky areas and scrub in Asia, Africa and North and South America.
Staples of the modern butterfly garden they are also attractive to moths and bees. Breeding is resulting in more compact cultivars of davidii with sterile seed, an important attribute because of its invasiveness.
