Native Plants
The small white asters lighting up woodland edges and shady garden corners right now are calico aster, a native that feeds late-season bees and butterflies when little else is flowering.
Calico aster is a bushy native wildflower with tiny white daisy-like blooms that flower in early fall. People in Canada posted 407 sightings of it in the past week, up from 284 the week before. As the bloom peaks, more folks are noticing it along trails, roadsides, and in their own yards.
Key Findings
iNaturalist users recorded 407 calico aster observations in Canada in the past 7 days
That is up 123 from 284 in the prior 7 days, an increase of about 43%
