tall, yellow flowering shrub is extremely drought tolerant. It flowers in late summer/early
fall, and performs best if pruned each spring prior to regrowth.
Cornus sericea (Red-osier dogwood) – Showy, bright red stems
make this a favorite shrub for landscaping. It grows to about 8 feet and spreads
by layering. Produces white berries in fall. Deciduous, large leaves w/prominent
venation.

shrub can grow to 15 feet tall. It is moderately drought tolerant and produces a
purple-black fruit in summer that is favored by birds.
Fallugia paradoxa (Apache plume) - A drought tolerant 4-6 foot
tall shrub native to the Colorado Plateau, Apache plume grows well in the Treasure
Valley. It is in the rose family and produces simple white flowers through the summer.

early June. This shrub spreads vegetatively to form thickets, so it must be planted
accordingly. Bright red rose hips in fall and winter are showy and attractive to
wildlife.
Rubus parviflora (Thimbleberry) – Native to the understory
in many Idaho forests, thimbleberry grows best in partial shade and requires regular
irrigation. It spreads vegetatively similar to raspberries, but much more slowly.

feet tall, it produces small white flowers in summer and powdery blue fruits in
late summer. Blue elderberry has pinnately compound leaves, grows best in well-drained

Branches are opposite and somewhat spine-tipped, and its fruits are reddish-yellow and provide an excellent food source for birds. Will spread vegetatively. Drought tolerant and grows best in full sun.

Penstemon eatonii (Firecracker penstemon) - Perennial forb of the Great Basin (UT, NV; not native to Idaho). Easily grown in full sun, produces many red, tubular flowers from May to June. An excellent hummingbird attractant. Drought tolerant. Avoid overwatering. Relatively long-lived.
Penstemon fruticosus (Shrubby penstemon) - A low-growing (to 18” tall), semi-evergreen subshrub with large, blue to lavender tubular flowers in June and July. Requires well-drained soils and is longer lived than many other Penstemons.
