Xanadu Philodendron (Thaumatophyllum xanadu)

Xanadu Philodendron (Thaumatophyllum xanadu)

Xanadu (often still sold as Philodendron xanadu) is a compact, landscape-ready tropical plant loved for its dense, mounding shape and deeply cut, glossy green leaves. Unlike larger split-leaf types, Xanadu stays more manageable and naturally forms a full, rounded clump—perfect for patios, entryways, and warm-climate gardens. It can also be grown indoors in bright, indirect light.

Ideal for: tropical landscape beds, borders, patio containers, pool areas (filtered light), bright indoor spaces, and low-maintenance tropical greenery.
