Description

Symphyotrichum lateriflorum is a medium-sized aster that usually does not exceed a height of 3', with small flowers about 1/3" across. The central stems are horizontally branched, hence the specific epithet "lateriflorum". The common name "calico aster" is a reference to its flower disks that dramatically change color with age, from yellow at first, to deep-red and purple when mature. Flowers within a single cluster will therefore have very different colored centers, giving them a calico effect. The daisy-like petals can be pale blue or lavender, to almost pure white.

Cultivation

This species is easy to grow in average, moist to dry, well-drained soils. It will tolerate light shade, but to the detriment of flower production. Stems may be pinched back early to encourage branching, a denser appearance, and increased flower yield. Its low, spreading form and adaptability to dry conditions, make it a good choice for rock gardens and perennial flower borders. Bloom times will vary according to geographic location from July to October. Zones 3-8

Propagation

Propagate from seed.

Additional Notes

Symphyotrichum lateriflorum is believed to hybridize readily in nature with other white asters, making them difficult to distinguish.
