Description
Symphyotrichum dumosum is a dioecious perennial forb/herb.[2] The plant is stiff with leafy branches possessing numerous flower heads. Flowers consist of white to pale lavender rays with a yellow to brown central disk.[3][4] Rays are 3-5 mm long, 0.9-1.2 mm wide, and numbered between 8-15 per flower. Its roots are creeping, branching, short, stout, and herbaceous.[4]
Distribution
S. dumosum occurs from New Brunswick and Maine, south to Florida, westward to Texas and Oklahoma, and northeast inland to Wisconsin, Michigan and Ontario Canada.[2]
Ecology
Habitat
S. dumosum can be found in old fields, disturbed areas, pastures, woodlands, glades.[1] While widely found in the southern extent of its range, it is restricted to shorelines in the northern portion of its range.[3]
Phenology
Flowering occurs in late August through October,[1] although reports of flowering exist for several months throughout the year.[5]
===Fire ecology===-->
In a 47 year unburned Florida area (NB66), Symphyotrichum dumosum occurred in 31% of the 1 m2 plots; initially, it did not occur.Cite error: Invalid <ref> tag;
refs with no name must have content This may suggest it is not very tolerant of fire.
