Utricularia geoffrayi

A small terrestrial bladderwort from Indochina that grows among short grasses in and around rice fields and other seasonally wet open ground. It is probably perennial and flowers late in the monsoon, from September to December. Grow it like other tropical terrestrial bladderworts: hot, bright and constantly wet in a fine peat-sand mix, with a somewhat drier, slightly cooler spell in winter.

Where it grows wild

Wikipedia describes it as a terrestrial plant among short grasses in or around rice fields. That means open, sunny, seasonally waterlogged ground that is flooded or saturated through the monsoon and drier from December to March. The traps sit in wet soil among the grass roots.

Recorded from sea level to 1,300 m. Most measured records are lowland (the main site is at 7 m in coastal Cambodia), with a few at about 900–1,250 m in Thailand and Cambodia.
