Calathea tarrazuensis

Calathea tarrazuensis is a Costa Rican prayer plant described by Helen Kennedy in 2011 (Novon 21). It is known from a few dozen collections in premontane wet forest at 650–1450 m (median 900 m), and little has been published about it beyond the original description. Grow it like other understory Calathea from mid-elevation Central American forest: warm, humid, shaded and evenly moist.

Where it grows wild

Recorded from premontane wet forest in Costa Rica. Like most Calathea it is a terrestrial herb of the shaded forest floor, usually in moist, humus-rich soil. The details here are inferred from the genus and the measured sites, not from a species account.

Recorded elevations 650–1450 m (median 900 m).
