Buddleja davidii

Semievergreen to deciduous. Native to China, Japan. Fast, rank growth each spring and summer to 3, 4, or even 10 ft. tall and as wide. Tapering leaves are 4–12 in. long, dark green above, white and felted beneath. In midsummer, branch ends are adorned with small, fragrant flowers (lilac with orange eye) in dense, arching, spikelike, slender clusters 6–12 in. long or more.

Needs good drainage and enough water to maintain growth. Cut back heavily before spring growth begins. May die to the ground in freezing weather but will regrow from roots like a perennial and bloom the same year. Invasive in disturbed soils in parts of Oregon and Washington.
