Asian Moon Summer Lilac

Buddleja x 'Asian Moon'

A wonderful new Buddleja with a huge advantage - it is sterile, producing no unwanted seedlings, longer lasting flowers and an extended blooming season! Purple tubular flowers with orange throats appear from summer until frost, a treat for hummingbirds. This rounded shrub makes a perfect accent or background plant. Deciduous.
