Invasive Species: Schefflera actinophylla, Octopus Tree
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. (7 mm) in diameter. Octopus tree is native to Australia and was introduced into Florida in 1927 as an ornamental. Plants can tolerate a wide range of sun and moisture levels but are restricted to areas with minimum temperatures above 35°F (1.7°C).
