Penstemon heterophyllus ‘GMR White’
An unusual, bright white form of our native foothill penstemon that dazzles with dense blooms from spring to fall. Spring sees the emergence of soft yellow buds on this evergreen perennial, which then open as snowy fresh, tubular flowers. The showy flower stalks reach 18 inches to 2 feet and look spectacular cascading out of a container. A natural selection, its name is an abbreviation of Glendora Mountain Road, the area just north of Los Angeles where it was found. As beloved by hummingbirds and pollinators as the more common blue-violet form of this species and even more shockingly floriferous. Plant in full sun to very light shade where it will have good drainage, and provide occasional to no water. Thrives in large pots. Drought tolerant.
Penstemon heterophyllus ‘Margarita BOP’
A fine selection of a native penstemon from Las Pilitas Nursery where this chance hybrid seedling was discovered at the “Bottom Of the Porch”. Forms a tidy mound 18 inches tall by 2 ft. or so wide. Iridescent blue-purple tubular flowers in short spikes put on a good show over a long period in spring and early summer. The spent flower spikes should be cut off to encourage more blooming, better form, and longer life. Best in full sun with well drained soils and moderate to little water once established. 'Margarita BOP' has proven particularly adaptable and has survived longer than other cultivars. Hummingbird favorite.
Penstemon newberryi
As the common name implies, this beauty is native to the mountains of California, Oregon and Nevada, where it grows in rocky habitats at high elevations. Forms an evergreen mat, under a foot tall with thick, leathery leaves and gorgeous magenta-pink tubular flowers, in mid to late spring. Good drainage is a must for success and growing in a container is an option for those with heavy soils. Full sun to very light shade with occasional summer waterings. Can be challenging to cultivate, but well worth the extra effort. The showy flowers are highly attractive to hummingbirds and butterflies. Said to be deer resistant.
Penstemon newberryi v. sonomensis
This rare, perennial, inland beauty, found only in Sonoma, Napa, and Lake Counties, is a great addition to the dry, inland rock garden. A low mat of small, gray-green, succulent-like leaves gives rise to 5-12” stalks topped with clusters of chunky, tubular, magenta-red flowers with white, fuzzy throats and reproductive structures. Mature plants are no more than 2' wide. A native bee and hummingbird magnet. Plant in full sun with decent soil drainage. Little to no water once established.
Penstemon palmeri
Showy, grape-scented, pale pink flowers top blue-green, succulent-like foliage on vertical stalks reaching an astonishing 4 to 5 ft. in height. The bulbous flowers have given rise to the common name, ballon flower. Native to desert mountains of southern California and throughout the western United States. This penstemon is attractive to a multitude of pollinators, especially hummingbirds. Plant in full sun to light shade and provide good drainage. Drought tolerant once established. The tall but narrow flower stalks make this penstemon useful in narrow spaces where height is desired.
Penstemon pseudospectabilis
From the southeast corner of the state comes this surprisingly adaptable penstemon, with prolific displays of magenta-purple, tubular flowers with flared mouths. Large, serrated, gray-green leaves line stems in attractive pairs. Flower stalks rise 2 – 3 ft. in spring, drawing in hummingbirds and bees. Even though this species is from the desert, it does quite well in local gardens with good drainage, full sun and occasional irrigation once established. Several local butterflies use the desert penstemon as a larval food source, including the common buckeye, variable checkerspot and Edith’s checkerspot.
Penstemon rostriflorus
A wonderful addition to the dry garden, bringing late summer color through abundant, bright red, tubular flowers. Growing 2 - 4 feet tall and wide, with attractive, glossy foliage, that takes on red and bronze tones in winter. A late blooming Penstemon, beginning in July, provides copious nectar for hummingbirds as well as bees, butterflies, and moths. Tolerant of wide range of soils and conditions, plant in full sun to light shade with occasional water. Drought tolerant once established.
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. In summer, the large, saturated blue-purple florets are held in clusters on stems rising almost 2’ tall above a low, evergreen rosette of glossy, strap-like foliage, reaching 1' - 2' wide. Attracts a multitude of pollinators. Does best with decent soil drainage, and inland sites that provide seasonality—colder winters, and hotter summers. Drought-tolerant once established.
Penstemon spectabilis
A spectacular Penstemon native to dry, gravelly slopes of southern California and northern Baja. Demanding good drainage and full sun, this perennial grows 3 ft. or more tall with striking displays of lavender-purple tubular flowers. A challenging species with a sensational floral display, but can be short lived in northern California. Performs best in hot inland gardens. Take care not to over water. Highly attractive to hummingbirds as well as bees and butterflies.
Perideridia gairdneri
An interesting and rarely cultivated native perennial that grows in grasslands and meadows in central to northern California and the Sierra Nevada foothills. Narrow leaves emerge in the spring giving way to lovely 4 ft. tall flowering stems topped with umbels of delicate white flowers in the summer. Looks particularly nice in mass and livens up a meadow or grassland planting that may be waning in summer. Entice the anise swallowtail butterfly with a NATIVE larval food source. Plant in full sun to light shade with a little water. Allow to go dry after flowering.
Perideridia kelloggii
An interesting and rarely cultivated native perennial that grows in grasslands and meadows in central to northern California and the Sierra Nevada foothills. Narrow leaves emerge in the spring giving way to lovely 4 ft. tall flowering stems topped with umbels of delicate white flowers in the summer. Looks particularly nice in mass and livens up a meadow or grassland planting that may be waning in summer. Entice the anise swallowtail butterfly with a NATIVE larval food source. Plant in full sun to light shade with a little water. Allow to go dry after flowering.
Phacelia californica
A low elevation species inhabiting bluffs, open slopes, road cuts and canyons of our inner and outer Coast Ranges down through the central coast. Forms perennial clumps of crinkled gray leaves. Stout stems rise above the rosette one foot to 18 inches tall with large coils of lavender flowers. Excellent rock garden subject. Plant in sunny areas with good drainage where it will be drought tolerant, and will do fine with a little summer water. Phacelias are great for attracting bees and butterflies.
Phyla nodiflora
Vigorous, spreading ground cover native to California, North America and other parts of the world. It's a tough one, able to survive a wide range of conditions and soil types. Tolerates both drought and flooding, but best with occasional deep watering in full sun to very light shade. Flowers heavily over a long period with charming little heads of mauve-pink, lavender and white blossoms, delighting an assortment of bees and butterflies. This dense, carpeting plant makes a serviceable ground cover or lawn-like replacement, tolerating moderate foot traffic and occasional mowing. May look rough in the winter, but quickly recovers in spring. Free flowering and pollinator friendly.
Physocarpus capitatus
Handsome, deciduous shrub favoring wooded streamsides in California. Grows vigorously 4 - 8 ft. tall and wide. After leafing out in the spring, the shrub looks spiraea-like, covered with small clusters of white flowers followed by red capsular fruits. Best with light shade and some summer water, but will accept full sun in cooler areas. Keep bushy and in bounds with pruning.
Physocarpus capitatus ‘Tilden Park’
A rare and delightful prostrate form of the native ninebark from San Bruno Mountain. Makes a sturdy groundcover about 3 ft. tall and spreading to at least 6 ft. wide, featuring lush, bright green, maple-like leaves with white flower clusters in the spring. The blossoms give way to bright red seed pods in the summer. Sun to light shade with moderate water, but will tolerate dryish conditions in part shade once established. Clay tolerant.
Pinus attenuata
This closed-cone pine is found primarily along the Oregon-California border and in hotter coastal mountains down to Baja. Knobcone pines can reach anywhere from 25 to 80 ft tall, depending on the soil conditions. The conical-shaped, evergreen crown has an open habit with clusters of 4-5” needles on upward-curving branches. Distinctive, asymetrical cones persist on the tree for years, even decades, and add to the tree’s visual appeal. This chaparral and dry-woodland native needs very little water and does best in rocky, well-draining soils with full sun. More tolerant of nutrient-poor soils than most other pines. In very lean soils, trees can develop a stunted and contorted appearance which is quite striking. Deer resistant.
Pinus contorta ssp. bolanderi
A close relative of the shore pine, the pygmy pine occurs in the coastal pygmy forests of Mendocino Co. This rare and threatened pine only reaches a height of about 6 ft in the acidic soils of its native habitat but acts more like the shore pine in a garden setting, reaching up to about 30 ft in time. The upward reaching stems are clad in short needles with small cones produced on the ends. Provide full sun near the coast and a little afternoon shade inland. Needs moderate to occasional irrigation and decent drainage. Good container plant. Deer resistant.
Pinus contorta ssp. contorta
On windswept coastal bluffs from Mendocino Co. northwards resides this dense, picturesque shore pine. While small in stature on the weathered cliffs of our shoreline often reaching only 6-10 ft. in height, in a garden setting the shore pine is a small to medium sized tree, growing to about 30 ft. Short, dark green needles cover the stems with small cones. An excellent compact conifer for the medium sized garden or in a container where it stays more diminutive. Provide full sun and occasional deep irrigation once established. Needs decent drainage. Deer resistant.
Pinus jeffreyi
This stately pine hales from many of California’s mountain regions and is the dominant pine of the Tahoe basin. Features long needles and a broad trunk with deeply furrowed bark of orangy-red. Similar to the ponderosa pine but occurs at higher elevations and the bark has a distinctive vanilla scent. The cones are also larger than those of the ponderosa and don’t have sharp, outwardly protruding scales, hence the affectionate name “gentle Jeffrey.” Often reaches heights of over 100 feet with an open canopy. Provide good drainage and full sun to light shade. Drought tolerant and deer resistant.
Pinus muricata
The Bishop pine is native to the northern California coast from Marin to Mendocino. A medium to large sized tree with a beautifully rounded crown and long, gray-green needles. Distinguished from the more southerly Monterey pine by its smaller cones which prick the hand when held. The Bishop pine often cohabitates with redwoods and other coastal conifers. Drought tolerant once established except in interior locations where an occasional deep watering may be required. Generally reaches 40 to 70 feet in height. Deer resistant.
Pinus ponderosa
Often associated with the Sierra Nevada mountains, this majestic pine can be found in Sonoma County as well. Long, gray-green needles form bushy clusters at the ends of branches with cantaloupe-sized cones that emerge at the very tips. The bark at maturity is a colorful patchwork of orange-tan plates separated by deep grooves of dark brown. It can grow a couple of feet a year, and averages from 60 to more than 100 feet in height in a garden setting. Provide full sun to light shade with occasional deep waterings when young. Needs decent drainage. Deer resistant.
Pinus sabiniana
A distinctive pine native to chaparral areas of California’s foothills. Sometimes called ghost pine due to its long gray needles set against dark, furrowed bark. While fairly slow growing, the gray pine can reach a height of 80 ft or more in well-draining sites with ample sunlight. Native Americans prized the big, prickly cones for their large, edible seeds. Prefers full sun and requires minimal water once established
Plantago maritima
From coastal bluffs up and down the California coast comes this charming little plantain. Starting in late spring and continuing through summer, small, greenish-yellow flowers flank the top of slender stems up to 6 inches tall. The dense rosettes of narrow, succulent leaves provide a striking accent in a rock garden or nestled in crevices between pavers or stones. A good container specimen. Recognized for its edible and medicinal uses. Plant in full sun to light shade. Tolerates low to regular moisture. May spread vigorously by seed.
Platanus racemosa
This most Californian of trees from the southern and central parts of our state features stunning bark mottled white and grey on a large, sculptured trunk. The maple-like leaves create an open canopy on this stately tree which can reach up to around 80 ft. tall at maturity. Seeds are produced in fuzzy pom-poms dangling on short stems and are a great food source for birds. In autumn, the leaves can turn orangey-yellow before they drop, adding rare fall color to the California landscape. Makes its home in sunny, low-lying areas and canyons with moderate to occasional irrigation. A great shade tree for the large garden and a larval host for the Western tiger swallowtail butterfly. Deer resistant.
Populus fremontii
Fast growing riparian tree, native to watercourses throughout California. A tall and dramatic tree, 50 - 75 feet tall, with a spreading, open crown. The leaves are shiny, triangular to heart shaped, with coarsely serrated margins and flattened petioles. Turns beautiful shades of brilliant yellow in the autumn. The wind causes the leaves to flutter and rustle, making a whispering sound. Cottonwoods can be either male or female, with the female trees producing masses of cottony seeds. When young, the bark is smooth and silver gray, becoming thick and furrowed with age. They have wide spreading surface roots and sucker sprouts. An important wildlife plant, providing food and cover for a wide array of insects and birds. This major riparian species provides rich habitat value, soil stabilization, and expansive shade. Plant in full sun with plenty of space and regular to occasional irrigation.
