Where it grows wild

It grows in wet grassland and marshes, including Eragrostis turf on rocky ground and very wet seeping rocky banks. The traps sit in saturated soil among low grasses and mosses, and it also turns up on wet forest edges.

Wikipedia gives 1900–2500 m. Herbarium labels in GBIF give 2500 m and 2703 m in the Rugege/Nyungwe and Kibira highlands.
