Symphyotrichum ontarionis
Also called Ontario Aster, Lake Ontario Aster, Missouri Aster
Bottomland aster is a North American perennial wildflower that forms colonies from thick rhizomes and bears white-rayed, yellow-centred daisy flowers from July to October. It does best in partial shade with consistently moist soil, as in its native woodland edges and stream banks.
Symphyotrichum ontarionis (formerly Aster ontarionis) is a species of flowering plant in the family Asteraceae native to eastern North America. Commonly known as Ontario aster and bottomland aster, it is a perennial, herbaceous plant that may reach heights of 120 centimeters (4 feet). Each flower head has many tiny florets put together into what appear as one.
Symphyotrichum ontarionis occurs from Ontario and Quebec south to North Carolina and Texas. S. ontarionis var. ontarionis is found throughout most of this range, and is replaced by S. ontarionis var. glabratum in northern Ontario, Quebec, and Michigan. The species is typically found in shaded, moist soils that occur in moist forests and along stream banks.
