Queensland bottle tree
The Queensland bottle tree, native to eastern Australia, is named for its remarkable trunk. Brachychiton (roughly “short covering”) refers to a coating on the seeds, and rupestris means that it is found growing among rocks. This tree is not found in the wild in North America.
Identification: This tree can reach 70' (21 m), but is usually under 40' (12 m). The bottle shape, which develops only after 5-8 years, can reach a diameter of more than 6' (1.8 m). Flowers are yellow, in clusters. Fruits are woody, shaped like canoes.
