Dodonaea viscosa is Indigenous. New Zealand: Three Kings, North, South and Chatham Islands and is now widespread throughout the world.  Dodonaea viscosa is New Zealand's sole species of the genus: Dodonaea.  It is a shrub growing >3 m tall, and rarely >9 m tall. The leaves are simple elliptical, 4–7.5 cm long and 1–1.5 cm broad, alternate in arrangement, and they secrete a resinous substance. Hence a common name Sticky Hopbush. A study of leaves yielded carbohydrates, flavonoids, fixed oil, proteins and amino acids, saponins, steroids and sterols, tannins, and triterpenoids.
The flowers (7mm) are dioecious; small, yellow-green, lacking petals. The male and female flowers are generally on different trees. The yellow to orange-red flowers are yellow to orange-red and are produced on panicles about 2.5 cm in length. Flowering occurs spring to mid-summer. 
The fruit is a capsule (1.5 cm wide) with thin, flat, papery, rounded wings. This 3 sided pod contains 3 dark brown or black seeds. The pod is green, ageing to pink to tan. The fruits have been used as a substitute for hops.
The bark separates into long stripes. The wood is extremely tough and durable, and New Zealand's Maori have used Akeake to fashion clubs and other weapons.

It is more upright when young and spreading out with age (2m). It has lanceolate bronzy-green 10 cm long leaves which turn purple in cooler weather. Tolerates some shade but the colour is better if grown in full sun. Tiny green flowers in clusters mid-summer followed by brown maple-like seed capsules in late summer.
