Description

'Blue Star' kalmeris is a clumping blue flowered cultivar in the Asteraceae (daisy) family. 

It is somewhat tolerant of part shade, but will be at its best when situated in full sun.  The flowers can bloom singly or in flat-topped clusters.

Maturity can take two to five years for a plant to reach.  Over time a group of plants will spread to form a colony.  At that time, they are also ready to divide.   

Its blooms are perfect for your cut flower or dried flower arrangements.  

Cutting to the ground or deadheading after flowering may produce an additional fall rebloom.

Insects, Diseases, and Other Plant Problems:  No serious issues.  Root rot can occur in locations with improper drainage.  Powdery mildew can occasionally be an issue.
