Ribes x gordonianum
A special hybrid flowering currant created in England by Donald Beaton in 1837 between our western U.S. Ribes sanguineum and the central U.S. Ribes odoratum. The fragrant flowers hang in dense dangling clusters in late spring and produce a dazzling color display with warm coppery red on the outside and yellow on the inside. The green maple-like leaves are deciduous. Robust and spreading, this currant grows to about 6 ft. tall and 8 ft. wide. Provide full sun to light shade and give moderate water.
Romanzoffia californica
The California mistmaiden is diminutive, reaching a bit over a foot tall when its dainty white flowers are in bloom. The bell-shaped blossoms appear in winter, perched in clusters on tall, thin stems above lush foliage. Summer dormant until the first autumn rains, this plant is often the first garden greenery to return after a hot, dry summer. At home in the Coast Range from the Santa Cruz Mountains north to Oregon, it requires light shade and decent moisture during the growing season. Allow to go dry when the rains stop. Great for rock gardens and small nooks with excellent drainage.
Rosa californica
A thicket forming, deciduous shrub native to riparian zones throughout the state. Fragrant, pink blossoms with yellow centers are followed by attractive red fruits or rosehips. The stems are lined with little thorns and gray-green, pinnately divided leaves. A good screen or living fence, where it will grows at least 5 ft. tall and usually spread wider. Very important for erosion control along streams. This is one of our most popular hedgerow plants due to the cover it provides for foraging wildlife and the value it offers to pollinators and birds. Prefers full sun to light shade and seasonally moist soils, but can go a little drier in the summer. A larval host to several butterflies.
Rosa nutkana
Named for the Nootka Sound in Alaska where it was originally described, this shrub's range runs all the way south into California. Forms prickly thickets at least 6 feet tall with light green foliage. Super fragrant, 2-3 inch single pink flowers appear in summer followed by showy red hips.Favors moist sites in full sun to light shade.

Rubus parviflorus ‘Dr. Stasek’
Bob Hornback found this interesting form of thimbleberry. Instead of the usual single white flowers, this cultivar offers double flowers. The extra petals are a nice touch against the background of large velvety leaves. Thimble-shaped edible berries follow which are mild flavored but sweet and much enjoyed by birds. Grows 3 - 6 ft. tall and spreading. Needs part shade and moisture.
Rubus spectabilis
Native to moist places in and about the woods of coastal Northern California. Forms an upright shrub that arches at the tips, growing easily 6 ft. by 6 ft. Dark green foliage with weak prickles can form a dense hedge. The dark pink flowers resemble small single rose blossoms and are followed by showy orange-red berries that look like salmon eggs. Wildlife relishes the fruit, people too, though they aren’t as tasty as blackberries. Grows best with summer water and some shade.
Rubus ursinus
Not to be confused with the weedy non-native Himalaya berry that has taken over acres in northern California. The native blackberry when happy can form a good sized patch, growing to about 3 ft. tall and spreading more than 6 ft. wide depending on available moisture. This thorny, spreading evergreen has excellent habitat value. The berries are widely used as a food source for wildlife. Offers excellent escape and nesting cover and is good for erosion control. People relish the berries and its fruits are highly prized for pies and jam. Best with some shade and moisture, but is drought tolerant once established.
