Tree philodendron, most commonly known botanically as Philodendron bipinnatifidum (long sold under the now-outdated synonym Philodendron selloum), is native to the tropical rainforests of South America, with documented wild populations across Brazil, Bolivia, Argentina, and Paraguay. It belongs to the arum family, Araceae, and its taxonomic history is genuinely in flux: some botanists have recently reclassified the species into an entirely separate genus, Thaumatophyllum, as Thaumatophyllum bipinnatifidum, based on updated molecular research distinguishing this subgroup from the broader Philodendron genus, though "Philodendron bipinnatifidum" and the older "Philodendron selloum" both remain in extremely wide use across the nursery trade and general horticultural literature, meaning a buyer or grower is likely to encounter all three names attached to what is fundamentally the same plant. Beyond its ornamental value, the plant's fruit, while requiring proper preparation, has some documented culinary use in parts of its native range, cooked and eaten in ways broadly similar to how other starchy aroid fruits and corms are prepared across various South American culinary traditions — a practical dimension to the plant's history that stands somewhat apart from its now much more prominent role as a large-scale ornamental foliage specimen worldwide.

Unlike the many vining Philodendron species that climb using aerial roots, tree philodendron develops a genuinely distinct, semi-woody, self-supporting, tree-like or shrub-like stem — a structural difference significant enough that botanists classify it within a separate subgenus, Meconostigma, alongside a small number of other similarly non-vining, arborescent Philodendron relatives. This stout central stem can eventually reach over three metres in height given enough time and space, topped by an increasingly dramatic crown of large, deeply lobed, almost feathery-looking leaves that can stretch up to three feet in length, radiating outward on long petioles from the central growing point. As the plant matures, it also develops thick aerial roots descending from the stem, which, while the species is not epiphytic and doesn't require a host tree to survive, can sometimes use nearby tree trunks or other structures for additional physical support in the wild.
