Arrowhead plant, botanically Syngonium podophyllum, is native to the tropical rainforests of Central and South America, where it grows as a climbing vine, using aerial roots to ascend tree trunks toward brighter light in the forest canopy, much like several of its aroid relatives. It belongs to the arum family, Araceae, and has earned the Royal Horticultural Society's Award of Garden Merit, a mark of its horticultural reliability. The plant's genus name comes from the Greek "syn," meaning together, and "gone," meaning womb or reproductive organ, a reference to the fused ovaries found in the plant's small flower structures, though the plant is grown overwhelmingly for its foliage rather than any expectation of bloom. The plant's flowers, when they do occur, produce a spike of tiny green-to-greenish-white blooms surrounded by a sheathing green-white bract called a spathe, arranged in clusters at the leaf axils — a typical arum-family flower structure, though visually unremarkable and rarely, if ever, the reason anyone chooses to grow this plant.

The species' defining and most horticulturally interesting trait is the dramatic transformation its leaves undergo as the plant matures. Juvenile arrowhead plants produce simple, solid, arrow- or heart-shaped leaves, often richly marked with silvery-white veining, giving the plant both its common name and one of its alternate names, goosefoot plant. As the plant ages and its growth habit shifts from a compact, shrubby young form to a genuine climbing vine, the leaves undergo a striking structural change, becoming compound and segmented into anywhere from three to as many as eleven slender, finger-like leaflets radiating outward from a central point — a transformation so pronounced that a mature, lobed-leaf specimen can look almost unrecognizable compared to the simple arrowhead-shaped leaves of a young plant, and one that has led some growers to specifically prune back climbing stems if they prefer to preserve the plant's more compact, arrowhead-leafed juvenile appearance rather than let it mature into its vining form. Repotting is generally needed every two to three years, and trimming the root system somewhat during repotting, alongside regular stem pruning, helps keep an otherwise vigorously growing plant at a manageable size for indoor display rather than allowing it to sprawl unchecked.
