Utricularia lazulina
A tiny annual terrestrial bladderwort, described by Peter Taylor in 1984. It is endemic to the coastal laterite country of southwest India, around Mangalore and in northern Kerala. It appears only during the monsoon, in shallow pockets of waterlogged soil on open laterite plateaus and in wet grassland, and produces true-blue flowers with a white palate. It then dies as the land bakes dry. In cultivation it is grown from seed each year as a hot, sunny, permanently wet annual.
Where it grows wild
Herbarium labels from the Kulshekar laterite plateau near Mangalore read 'in shallow pockets of wet soil over laterite, abundant', with 'corolla true blue with white bulla with blue nerves'. Wikipedia describes the habitat as shallow wet soils over laterite or wet grasslands. Recent observations come from laterite hills in Kannur district (Madayipara, Kunnaru) and from around Kozhikode. These rock plateaus are open and treeless, flooded in the monsoon and bare and scorched in the dry season.
Coastal lowland: the specimen labels give 60 m, and the measured sites are at 9–50 m.
