Drosera indica

Indian sundew

A fast-growing annual sundew with long, narrow, sticky leaves up to 10 cm, found across tropical Africa, Madagascar and tropical to warm-temperate Asia. Young plants stand upright, then the stem lengthens and scrambles over grasses, reaching 5–50 cm, with white, pink, orange or purple flowers. In the wild it grows in open, seasonally wet ground during the monsoon and survives the dry season as seed, so at home it is best treated as a warm, bright, wet-grown annual raised from seed.

Where it grows wild

It grows in open, sunny, seasonally waterlogged places: wet sand, laterite flats and seepages, grassland that ponds in the rains, swamp and pool margins and drainage channels. Plants appear with the rains, flower and set seed within a few months, and die as the ground dries.

Recorded from 1 m to 1675 m, median 350 m (95 records); mostly lowland to low hills, such as the laterite plateaus of the Western Ghats.
