Cherry-like, green-brown berries are encased within green or black mottled calyces. The mature fruits can resemble a lantern. The plant usually germinates in late spring or early summer.

Rubus ellipticus is a stout evergreen shrub with prickly stem that grows approximately 4.5 metres tall. Its stems are covered with prickles and reddish hairs. It has been introduced to several places, including Hawaii, Southern USA and the UK, and is grown in cultivation for its edible fruits. This plant has become a major pest in Hawai'i, threatening its own native species of raspberry (Rubus hawaiiensis), and the ability of this plant to thrive in diverse habitat types makes it a particularly threatening invasive plant.

Published in Invasive Plants

Evergreen shrub or broadly conical tree up to 12m high. Dark green, shiny leavers tapering at both ends and usually wavy margins at the end of the branches. Fragrant white flowers in terminal clusters from August to September. Showy, orange turning brown capsules.
