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. The flowers are very similar in appearance to those of aster and boltonia. Plants typically grow to 12-18” tall. Oblong-lanceolate green leaves (to 3-4” long). Synonymous with Boltonia incisa ‘Blue Star’.


2019 – Begins to grow timidly at the end of March. Very well-developed at the beginning of May ( in the midst of the Angélique tulips). In bloom at the beginning of July. First flower on July 11. Quite well flowered at the beginning of August. Several seedlings that have reseeded begin to flower in early September.

2018 – Purchased at the Cesson-Sévigné plant festival. 2 x 2 L. pots on the Bellec nursery stand and 3 plugs on the Vincent Besnard nursery stand. Planted at the end of September in the West border, between Hebe pimeleoides “Quicksilver” and Deutzia “Nikko”.
