Identification: Cherokee Rose is a fast growing, climbing rose that can grow 10-12 ft (3-3.6 m) tall and produces dramatic 3.5–4 in (9-10 cm) wide white flowers with yellow stamens. It has pinnate leaflets of 2-3 leaflets. It has smooth and shiny leaves. The fruit, or rose hip, is large (1.5–2 in or 3.8-5 cm long) and are covered in thorny hairs.
Impacts: This rose is native to China and Southeast Asia. It was brought to the continental United States by early colonists and quickly naturalized throughout the Southeastern United States. It became so prevelant that it was adopted as the "native" state flower of Georgia in 1916. It can overgrow other shrubs and trees and the thorny canes can impede passage. In Hawaii it is naturalized on Lanai, Kauai, and a few locations on the Big Island. Please let someone know if you find it on your island!
Dispersal Mechanism: Cherokee rose reproduces vegetatively (by cuttings or root runners). It is moved around by humans as a garden or horticultural plant.
