Populus tremuloides
From mountain meadows and hillsides across the Sierra Nevada comes this iconic native poplar. Smooth, white bark and rounded leaves which quake in the wind make this slender tree highly ornamental. Reaches a height of at least 20 ft. and spreads by underground roots to form groves. While the fall color may not be quite as stunning in lower elevation gardens as it is in the mountains, colder parts of our area will still see leaves of yellow, orange and red in the autumn. Easily grown at lower elevations, this form is reported to be particularly disease resistant. Needs full sun to light shade and regular to moderate irrigation once established. Lower irrigation should slow aspen’s ability to multiply.
Potentilla gracilis
Prolific displays of bright yellow flowers resembling buttercups make this little cinquefoil a hit from spring through autumn. Flowers are held on two foot stems above low mats of dissected,dark green leaves. Native to mountainous areas throughout California. Provide full sun to light shade and give occasional to regular moisture. Will spread slowly by seed if exposed soil is nearby. A favorite of bees and butterflies. Deer resistant.
Prunus ilicifolia ssp. ilicifolia
Hollyleaf cherry is a large, evergreen shrub that can grow more than 15 feet tall and wide, but is easily pruned to be more compact. This adaptable foothill native can be clipped into a formal hedge, pruned to be treelike, or left to its own natural gumdrop-shaped habit. Often it is used for background or screen plantings. Glossy, holly-like leaves are accompanied by showy displays of creamy-white flowers in narrow spikes from late spring to early summer. Plant in full sun to very light shade. Looks best with occasional deep waterings, but can tolerate very dry conditions once established. Although it requires good drainage, it is tolerant of heat, drought, wind and oak root fungus. An excellent habitat plant, offering food and cover for wildlife. Birds enjoy the small reddish-purple cherries. Generally deer resistant.
Prunus ilicifolia ssp. lyonii
This subspecies of our native cherry comes from Southern California and can be grown as a large shrub or trained into a small tree. The Catalina cherry is evergreen, with soft, glossy leaves and without the toothed leaf margin of our more local hollyleaf cherry. Gorgeous, creamy-white flower clusters make a showy display in spring. The purple-red fruits are edible, but are mostly preferred by wildlife. At 20-40 feet in height and slightly narrower in width, it is also larger than the hollyleaf cherry, but is prunable to 8-10 feet. Its dense foliage makes an excellent hedge. Does best in well-drained soil with occasional deep watering once established. The flowers are adored by pollinators. Robins, finches, towhees, Cedar waxwings and mockingbirds eat the cherries.
