Distribution in the United States
In Hawaii, yellow Himalayan raspberry invades wet forest habitats at elevations between about 2000 and 5000 feet that have been disturbed by feral pigs.
Himalayan raspberry is a stout evergreen shrub with prickly stems about 12 feet long. Its thick leaves are about 3-4 inches long and 2-3 inches wide, divided into three roughly equal "finglers" with toothed leaf margins and inch-long leaf stalks that are densely covered with prickles. The flowers of yellow Himalayan raspberry are white and occur in short, terminal panicles. The fruit is yellow, edible and highly sought after.
Habitat in the United States
Yellow Himalayan raspberry is usually found in moist to wet forests. This species is well adapted to the full sun of open canopy forests and pastures as well as the deep shade of rain forests.
Life History and Behavior
Biology and Spread
Yellow Himalayan raspberry spreads rapidly by root suckers and regenerates from underground shoots after fire or cutting. Its seeds are dispersed by fruit-eating birds and mammals.

Ecological Threat in the United States
Where it becomes established, yellow Himalayan raspberry forms impenetrable thickets, threatening native lowland wet forests and displacing native Hawaiian plant species, including a native Hawaiian raspberry (Rubus hawaiiensis).
Rubus ellipticus commonly known as Yellow Himalayan raspberry is a thorny fruiting shrub that originates from South Asia. It is called hisalu,ashilo or aisayloo and is loved by children playing in the forests. It is sweet to the taste, though it is not harvested for domestic use. The fruit perishes quickly after plucking from the thorny bush.
