In bloom, it is a mass of tiny, white, daisy-like flowers that almost cover the whole plant. Will expand into a large patch, but is not aggressive. Asters are important plants for insects, including our native butterflies, which use them both as a nectar source and as food for their caterpillars. May sprawl.
Bloom time: August, September
Ht: 30-60 cm (12-24")
Sun; any soil.
Sow the seeds directly into the garden in late fall and they will germinate in the spring. If starting indoors, moist cold stratify for 2-4 weeks.
