Utricularia viscosa

A small perennial bladderwort, the only member of section Sprucea, that grows on wet sand and in shallow water in lowland savannas and coastal wetlands of northern South America and Central America. Treat it as a warm, full-sun bog or shallow-water plant: permanently wet, soft-water sand, strong light and tropical warmth all year.

Where it grows wild

Wet sandy savannas, seasonally flooded coastal restinga and dune hollows, swampy ground at the base of hills, damp sand in open cerrado, and rock pools beside rivers. It grows either on saturated ground or submerged in shallow water, among low sedges and grasses with little or no shade.

Mostly lowland: herbarium records run from near sea level to about 850 m, with half of the dated records below about 90 m; the literature gives up to 900 m in Guyana.
