Range: Senegal to South Africa and Madagascar, through tropical Asia and up to Japan, to northern Australia
A misfit sundew of the tropics, D. indica spreads from across most of tropical and South Africa, through subtropical and tropical Asia, and possibly still into northern Australia (at least, in its current taxonomic state) where it may be found growing in just about any location with wet or waterlogged, peaty or sandy soils. Once the only species in its complex, a dozen or so species have now been separated from it, the vast majority Australian endemics; several more species may yet be found in the wide variation still claimed under this taxon. Plants may reach greater than 50 cm in height, growing as long, narrow to sturdy erect or scrambling stems that support filiform to linear lanceolate leaves up to 10 cm in length. Color is highly variable, from solid green with white tentacles to wine red or nearly purple with maroon tentacles. Flower stalks are scorpioid cymes produced at the ends of the stems, bearing blooms on short to moderate length pedicels. Flowers may be anywhere from 0.5-2 cm across depending on form, with narrow ovate to broadly obovate petals of white, pink, purple, or even orange (though this last color may actually be misidentified specimens of D. aurantiaca). Current diagnostic traits for this species include full covering of all plant parts in white or red glandular trichomes (Asian versions possibly having larger red glands similar to D. serpens) and typically presence of filiform stipules at the base of the leaves, or simply the lack of diagnostic glands or hairs found in the other species.
Cultivation: Grow in a 1:1 sand/peat mix or any mix with a higher proportion of sand or aerating materials, kept moist to waterlogged and moderately humid, with warm to hot conditions year round. Sow seeds on soil surface, and grow in strong artificial light to full sun.
Lifespan and reproduction: Annual. Reproduces through seed only, though propagation may be possible via stem cuttings.
