Philodendron speciosum

A large, self-heading Philodendron from Brazil and Bolivia, now often placed in Thaumatophyllum as T. speciosum. Wild records are few; old specimens come from Minas Gerais and São Paulo. Grow it like its relatives in Thaumatophyllum: big pot, bright light, warm summers and a cooler, drier winter.

Where it grows wild

Wild habitat is poorly documented in the sources checked. Its relatives in Thaumatophyllum grow as large terrestrial or rock-rooted plants in fairly open forest, forest edges and outcrops in south-eastern Brazil.

No elevations on record; the Minas Gerais collections (Serra da Babilônia) are upland sites.
