Drosera cayennensis

A small rosetted sundew of seasonally wet savannas from Costa Rica and Panama through northern South America to Bolivia and central Brazil. It is a seasonal geophyte: it grows and flowers in the wet season and survives the dry season as dormant roots. Growers need to allow this dry-season rest or keep it growing warm and wet all year.

Where it grows wild

Sandy and clayey soils in seasonally wet savanna in the Cerrado and Amazon domains, and in campo rupestre on sandy clay with quartz gravel, in full sun.

Sea level to about 1600 m; median record elevation 375 m, so mostly warm lowlands.
