Heptapleurum actinophyllum, or the octopus tree, a tropical evergreen with distinctive palmately compound leaves and is known for its striking appearance

Heptapleurum actinophyllum, commonly known as the Australian umbrella tree, Queensland umbrella tree, octopus tree, or amate, is a striking tropical evergreen tree native to the rainforests of Australia, New Guinea, and Java. Its distinctive appearance, particularly its unique leaf structure, has made it a popular ornamental plant in many parts of the world.

The most notable feature of this tree is its palmately compound leaves, which resemble the tentacles of an octopus. These leaves are composed of a cluster of seven to sixteen leaflets radiating from a central point. Each leaflet is typically oblong or elliptic in shape and has a glossy, dark green color. The leaves are arranged in whorls at the ends of long, sturdy petioles, creating a dramatic and umbrella-like effect.

The octopus tree can grow to a height of 15 meters (50 feet) and often develops multiple trunks. It is a fast-growing plant that thrives in warm, humid conditions. In its natural habitat, it is often found growing as an epiphyte, clinging to other trees for support.

While the tree is primarily known for its striking appearance, it also produces small, red flowers arranged in racemes. These flowers are followed by fleshy, purple fruits that contain seeds. The octopus tree can be propagated from seeds, cuttings, or by air layering.

Due to its attractive foliage and relatively low maintenance requirements, the octopus tree is a popular choice for gardens and landscapes in tropical and subtropical regions. It can also be grown as a houseplant, although it may require special care to ensure optimal growth indoors.
