Triantha glutinosa — sticky false asphodel

Facts

Sticky false asphodel is found in marshes, wet meadows and river shore seeps on calcareous soils in Maine, New Hampshire and Vermont. Because of this habitat specialization it is considered locally rare in New Hampshire and Vermont, where it occurs only along the Connecticut River.

Habitat

Fens (calcium-rich wetlands), floodplain (river or stream floodplains), meadows and fields, shores of rivers or lakes
