Silverberry & Goumi Berry
Silverberry E. ebbingei & E. pungens
At a glance these two species are easy to confuse. Their evergreen leaves look alike and their nodding white & brown flowers bloom reliably every November. Both are really tough, accepting the hottest and driest and windiest conditions Portland can offer. Run your hands along a branch though, and you'll quickly discover the difference. Thorns! The thorns on E. pungens are up to 2" long & they hurt so beware. Plant this in a spot where it can grow without being pruned. E. ebbingei is the kinder gentler version with nice smooth stems.

Sweet Scarlet Goumi Berry
Grown for red berries that taste like pie cherries, Goumi Berries have sweet smelling white flowers in May and are easy to care for, bug & disease resistant shrubs. Plants are self-fertile but will produce more if planted with another variety. Berries ripen in July. (Photo credit to One Green World).

Autumn Olive is not related to true olives, which depending on how you feel about olives could be a good or bad thing. This has nutrient rich red or amber berries in September and fragrant white flowers in May. It's self fertile, cold hardy and reports to improve soils where it's planted.
