Aster incisus

Common Name(s):

Previously known as:

  • Asteromoea incisa
  • Boltonia incisa
  • Kalimeris incisa
Phonetic Spelling
ASS-ter in-SY-sus
Description

Kalimeris is a flowering, rhizomatous, herbaceous perennial native to Southeastern Siberia, northern China, and central and southern Japan and is a member of the daisy family (Asteraceae). It is typically found in grasslands, thickets, meadows, or along roadsides in its native habitat and is clump-forming, growing 1 to 4 feet tall. Daisy-like flowers with light blue or lilac blue petal rays and a yellow center appear on erect, leafy, branching stems from June to October. The foliage is dark green, oblong to lanceolate, with toothed margins. The genus name Aster is Greek, meaning "star." This refers to the arrangement of the flower heads. The specific epithet incisus is Latin, meaning 'having been cut or notched."

Prefers full sun to partial shade and moist, well-drained soils. It is adaptable to clay soils, moist and dry conditions, and hot, humid weather. In early summer, pinching back the foliage will stimulate the plant's growth. After blooming, cut back the spent flowers to encourage fall re-blooming. Propagate by division or root cuttings in the spring. Divide the plant about every 3 years to maintain its size and health.

Recommended for cottage gardens, rock gardens, or along borders. Mass planting and small groups would be more impactful.

Insects, Diseases, and Other Plant Problems:  No serious issues. Monitor for slugs and snails. May be susceptible to verticillium wilt, gray mold, and powdery mildew.  Root rot can occur in locations with improper drainage.
