About Polemonium vanbruntiae Britton
Polemonium vanbruntiae Britton is a perennial herb that grows erect from a horizontal rhizome, reaching a maximum height of one meter. Each of its leaves is composed of 7 to 10 pairs of lance-shaped or nearly oval leaflets. The inflorescence is a corymb bearing purple-blue flowers with yellow centers. The stamens and stigmas protrude out of the bell-shaped corolla. This species is similar to Polemonium caeruleum and Polemonium reptans.
In terms of distribution and growth habit, Polemonium vanbruntiae ranges from New Brunswick and Quebec in the north southward to Maryland and West Virginia. It is not common across its range, but it is likely most abundant in New York. It can grow in a wide variety of wetland habitat types, including swamps, bogs, marshes, and wet areas along roadsides. Its habitat is typically saturated with water, but not flooded.
Ecologically, Polemonium vanbruntiae can reproduce both sexually and vegetatively, though the relative importance of these two reproduction methods is not currently known. Plants of this species usually flower from mid-June to late July. Polemonium vanbruntiae is sometimes cultivated for use in gardens.
