Buddleja 'Asian Moon'

Buddleja 'Asian Moon' is a sterile hybrid cultivar developed in response to the popularity, horticulture merit yet high weediness of the 'Butterfly Bush' B. davidii Franch.. The highly invasive nature of this species has led to its proscription in parts of the USA prompting a number of studies into sterile hybrids. 'Asian Moon' was raised in 2001 by researchers at the University of Arkansas by crossing the tetraploid davidii cultivar 'Moonshadow' (female parent) with the diploid B. asiatica Lour. (male parent), to create a seed-sterile triploid.

The inflorescences appear in late May to early June, and comprise numerous panicles of pale purple flowers, followed by vestigial fruits devoid of seed.
