Ecology
Habitat
S. praecox is found in savannas, swamps, woodlands, meadows, pinelands, dunes, swales, and bogs.[1][4]
It is also found in disturbed like including vacant lots.[4]
Associated species: Tradescantia, Amorpha, and Spigelia.[5]
Phenology
S. praecox has been observed to flower from March through July[1] with peak inflorescence in April and May. A report of flowering in December also exists[6] and in New England, it is said to complete its bloom by the end of the second week of September.[3]
