This tatarian aster is an erect, tall-growing species (to 6') which seldom requires staking. Distinctive paddle-shaped, lower leaves are up to 24" long and 6" wide, but leaves are significantly smaller in size higher up on the plant. Small but abundant flowers (to 1" across) with deep lavender to blue rays and yellow centers appear in flat-topped clusters in autumn. A late blooming aster that still looks fresh at time of first frost. Attractive to butterflies.
No serious insect or disease problems. Staking may be necessary if grown in moist, fertile soils.
A tall aster for the back of the border or for naturalizing in a wildflower area.
