Drosera madagascariensis

A tall, stem-forming tropical sundew from bogs and seasonally flooded grassland across tropical and southern Africa and Madagascar. Stems reach about 25 cm and then lean over or scramble through surrounding grass, carrying spaced spoon-shaped traps on long petioles. It likes warmth, strong light and constantly wet peat, and does well in a bright, humid terrarium or a sunny tray.

Where it grows wild

Sphagnum bogs, swamp margins, waterlogged peat and seasonally inundated grassland, including seepages on inselbergs and open highland marshes. Plants grow among sedges and grasses, which the older stems lean on.

Recorded from about 400 m (Batéké plateau, Gabon) up to about 1,750 m on Madagascan inselbergs; Ugandan lakeside bogs are around 1,100 m.
