Blue Woodruff

Asperula orientalis
An annual relative of sweet woodruff, this freely blooming plant is a treasure. Clusters of tiny trumpets in bright lavender-blue bloom all summer long with little care, the clouds of flowers waving above the whorled leaves creating a softly mounded form. Described in 1935 by Hottes in The Book of Annuals, and uncommon in gardens–we hope to change that!

Shear midseason as seedheads begin to form for a enthusiastic rebloom until fall. Self-sows.
