Kalimeris incisa, commonly called kalimeris, is a clump-forming perennial that is native to meadows and open ground in northeast Asia. Specific epithet means deeply and irregularly cut. ‘Blue Star’ is a clump-forming perennial that is noted for its long summer bloom of daisy-like flowers (1” diameter) featuring light blue rays and yellow centers.
