Octopus tree is invasive and can grow to 40 ft. (12.2 m) tall. Stems can be single or multi-stemmed. Leaves are palm-like with 7 to 16 leaflets. Leaflets are ovate, entire, and 12 in. (30 cm) long. Flowering occurs in summer to early fall, when large red inflorescences develop at the stem tips. Flowers are red and 1 in. (92.5 cm) wide. Fruits are round, dark purple, and 1/4 in.
