Trumpet Gooseberry grows on
dry hillsides, primarily south of Denver and on the west slope. Sharp spines,
about 1 cm long, arise from the nodes. White flowers appear mostly in pairs. The
outside of the flowers is densely pubescent. Anthers are red. Leaves are palmately
lobed.
Compare to Ribes cereum (Wax Currant),
which lacks spines and has less pubescence on the outside of the flowers. Wax
Currant is more common than Trumpet Gooseberry.
