Penstemon rydbergii
A widespread species native to much of the western United States, including California, growing in mountainous regions in moist meadows and along streams. Forms a low rosette of bright green leaves topped with flower stems 1 -2 foot tall. The small, lavender-purple, tubular flowers are clustered in whorls on dense spikes. The blossoms offer an excellent source of nectar and pollen to hummingbirds, bees and butterflies, as well as a larval food source for a number of butterfly species. Considered easy to grow and long lived. Plant in full sun to light shade with regular moisture. Somewhat winter deciduous. Deer resistant.
Penstemon speciosus
Found in higher elevation localities of inland Northern California, royal penstemon is a vibrantly colorful addition to the dry, full sun garden.

Native to moist areas usually near coniferous forests and woodlands. Creeping perennial forms a low dense mat of foliage. Upright spikes of purple flowers over a long period summer - fall. Give some thought to placement because if happy it will reseed vigorously. Plant in full sun or light shade with regular water.
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.
Ptelea crenulata
This interesting California endemic deserves wider use in California gardens. Hoptree is a deciduous, large shrub/small tree, growing 6 - 15 ft. tall, in the citrus family. Native to hot, interior coast ranges and the Sierra Nevada foothills, often growing in canyons where residual moisture can be found. Glossy, green, fragrant, trifoliate leaves with panicles of small creamy-white flowers decorate the branch tips in spring. Handsome, circular, flattened, fruits which look like hop seeds, start out green and age to tan and may hold on after the leaves have fallen in the autumn. Plant in full sun to light shade with occasional, deep summer watering. The fragrant flowers are attractive to a variety of pollinators including butterflies. A larval host for the two-tailed swallowtail butterfly.

Native to open woodlands and meadows, this buttercup often occurs under deciduous oaks and buckeyes or on edges of forests. Perennial, with basal foliage, the flower stems rise 12 to 20 inches with bright yellow shiny petals. Has been surprisingly adaptable. Does fine with moderate summer irrigation, where it stays evergreen and long blooming. Once established can be allowed to go summer dry, where it will go dormant after setting seed, and returning with the winter rains.
