Identification:
Yellow Himalayan raspberry is a rambling shrub that grows up to 15-20 feet tall and is covered with stout prickles. It is the only raspberry with light green heart-shaped leaves growing in a three-leaflet pattern. The leaves average 2" to 3" long and have saw-like edges with rounded tips. The white flowers are small (3 to 10 mm wide) and are covered in bristly hairs. Yellow Himalayan raspberry is also the only raspberry with yellow fruit (1" long).
Impacts: Yellow Himalayan raspberry spreads by vigorous vegetative growth as well as by birds and other mammals that eat the fruit. It is hard to kill once established.
Dispersal Mechanism: Yellow Himalayan raspberry is spreading as a contaminant in hapu'u fern trunks and parts, such as mulch. Humans transport the plant long distances for use as an ornamental or as an edible crop. It can also be spread by birds and mammals that eat the fruit. Yellow Himalayan raspberry is a rambling raspberry bush that is out of control in forests on the island of Hawaii. If you see it anywhere else on Maui or Kauai let someone know!
