Umbrella tree, botanically Schefflera actinophylla and increasingly reclassified in current botanical literature as Heptapleurum actinophyllum, is native to tropical rainforests and gallery forests of eastern Australia, particularly Queensland and the Northern Territory, along with southern New Guinea. It belongs to the ginseng family, Araliaceae, and the species epithet "actinophylla" comes from Greek roots meaning "rayed leaf," a direct reference to the plant's distinctive compound leaves, in which glossy, oval leaflets radiate outward from a central point on long leaf stalks, arranged much like the ribs of an open umbrella — the source of both its most common name and its equally popular alternate nickname, octopus tree, drawing on the same radiating visual pattern seen from a different angle. The plant's mature compound leaves typically consist of seven to sixteen individual leaflets, each glossy and oval-shaped, radiating from a central point in a pattern that becomes considerably more pronounced and visually dramatic as the plant matures from a young, simpler-leaved specimen into a fuller, more established one.

In its native Queensland habitat, the species grows naturally as an epiphyte in its early life stages, germinating high in the branches of a host tree after a bird disperses its seed there, before eventually sending roots downward and establishing more independently — a growth pattern echoing, on a smaller scale, the strangler-fig-like strategy seen in some other tropical trees. Mature wild specimens can reach roughly 40 feet, developing either a single or, more commonly, multiple woody stems, and produce dramatic clusters of small red flowers arranged on long, umbrella-rib-like floral spikes that can themselves reach several feet in length, followed by round, dark purple fruit that birds readily eat and disperse.
