Arctostaphylos densiflora ‘Howard McMinn’ (Howard McMinn manzanita)

LEAD Technologies Inc. V1.01Plant type: Evergreen shrub

Light: Sun to partial shade

Soil: Adaptable

Water: Drought tolerant to occasional

Bloom season:  Spring

Natural habitat: Chaparral, coastal bluffs, garden hybrid

Garden Usage: Large shrub, screen

 

Howard McMinn Manzanita is a large shrub which can grow to 8’ but can easily be kept pruned to 5’. Also 5’ to 8’ in width. The clean, fine textured foliage of Howard McMinn Manzanita combines or contrasts with nearly any plant; an excellent pairing places it near Saint Catherine’s lace.  It will tolerate summer watering and can take heavy clay soils.  This is an especially handsome shrub.  Plants naturally open up as they age and reveal the striking, twisted branching habit associated with manzanitas.  It blooms in the spring and is one of the last manzanitas to bloom with white to pale pink blossoms.

Arctostaphylos stanfordiana bakeri 'Louis Edmonds' - Louis Edmunds Manzanita

Plant Type: Evergreen shrub

Light: Sun to partial shade

Soil: Adaptable, well-drained preferred

Water: Drought tolerant to occasional

Bloom Period: Late spring

Natural Habitat: Garden hybrid

Garden Usage: Focal point or informal screen

 

This manzanita is favored by many native plant gardeners and features a unique, dark purple-mahogany bark on its elegant trunk and branches.  The sage gray leaves are highlighted with the numerous clusters of clear pink flowers.  Louis Edmonds manzanita has a distinctively upright growth habit 8 - 10 feet tall.  Use it as a focal point in the garden, or as an informal screen with toyon and sugar bush.  Prune this manzanita to highlight the beautiful bark.

 

Ceanothus thyrsiflorus ‘Skylark’ (Blue blossom wild lilac)

Plant Type: Evergreen shrub

Light: Sun to partial shade

Soil: Adaptable, well-drained preferred

Water: Drought tolerant to occasional

Bloom Period: Late spring

Natural Habitat: Garden hybrid

Garden Usage: Compact shrub

 

Ceanothus ‘Skylark’ is a good choice for gardens lacking space.  It has a compact, dome-like form and reaches about 4’ high to 6’ wide.  Blooms from late spring to early summer, which is later than most ceanothus.  You can prune spent flowers to improve this shrub’s appearance.  As with most ceanothus varieties, go easy on the summer water once it is established.

Eriogonum giganteum (St. Catherine’s Lace):

Plant Type: Evergreen subshrub

Light: Full to part sun

Soil: Adaptable

Water: Drought tolerant to occasional

Bloom Season: May to December

Natural Habitat: Channel Islands

Garden Usage:  Background shrub

 

Saint Catherine's Lace is our largest species of Buckwheat growing to 4 feet. In summer and fall this buckwheat provides a show of large, spreading clusters of creamy-white flowers which form a canopy over the pale gray foliage. The flowers take on a rusty hue as they age, and remain on the plant until the first hard rains, or can be removed earlier and used in arrangements.

Phlomis fruiticosa (Jerusalem Sage):

Plant Type:  Evergreen subshrub

Light: Full Sun

Soil: Normal, sandy, clay

Water: Drought tolerant to occasional

Bloom Season: Late spring, early summer

Natural Habitat:  Mediterranean

Garden Usage: Accent, border, containers, cut flower

 

Phlomis fruticosa (Jerusalem Sage) is native to the Mediterranean region. This is a large, multi-stemmed, broad shrub growing to about 4'x 4' with large (2-3 inch long) lance-shaped, soft woolly gray leaves that are white beneath, and 1 inch long, bright lemon yellow woolly flower whorls that appear on erect stems spring through summer. Plant in full sun to light shade. Drought tolerant and cold tolerant to at least 23 degrees F. This plant is attractive to butterflies and birds.

Rhamnus californica ‘Mount San Bruno’ (Coffeeberry)

Plant Type: Evergreen shrub

Light: Sun to shade

Soil: Adaptable; well-drained preferred

Water: Drought tolerant to occasional

Bloom Season: Spring

Natural Habitat: Widespread in many plant communities below 7000 ft, garden hybrid

Garden Usage: Informal hedge or screen, formal foundation shrub, woodland theme

 

Coffeeberry is one of the most common evergreen shrubs encountered in coastal California and is quite adaptable in many garden conditions.  ‘Mound San Bruno’ features narrow light green leaves and a tightly branched, mounding habit to 5 feet tall and equal spread. The berries develop through a series of interesting colors-lime green, rose, and red – before turning burgundy-black in autumn.  The ripe berries are attractive to small mammals and birds, especially mockingbirds, but can stain a patio, so keep this in mind when placing it in the garden.

Ribes aureum (Golden Currant):

Plant Type: Deciduous shrub

Light: Sun to partial shade

Soil: Adaptable

Bloom Season: Mid winter

Water: Drought tolerant to occasional

Natural Habitat: Coastal scrub, chaparral and woodlands below 2500 ft.

Garden Usage: Broad shrub, deciduous, attracts birds, plant with toyon, coffeeberry, coast live oak, ceanothus

 

Golden currant is a broad, sprawling shrub reaching as much as 10 ft tall.  Clusters of yellow flowers form in midwinter and develop a reddish cast as they fade.  They have bright glossy green leaves that offer early season color.  The translucent yellow-orange or black berries attract birds, and seedlings are common as a result.  Keep it pruned to avoid rangy thickets.

 

 

 

 

Ribes sanguineum var. glutinosum (Pink-flowering currant):

Plant Type: Deciduous shrub

Light: Sun to shade

Soil: Adaptable

Water: Infrequent to moderate

Bloom Season: Spring

Natural habitat: Open slopes, chaparral, moist woodlands below 2000 ft.

Garden Usage: Woodland garden, narrow corridors

 

 

Ribes sanguineum var. glutinosum ranges in size from 5 to 12 feet high.  The flowers are held in pendulous clusters 2 to 8 inches long and vary in color from silver pink to carmine red.  The medium to dark green, maple-like leaves are 1 ½ to 3 inches wide.  The powdered, blue-black berries are edible, but you’ll have to compete with the birds to get them.  Grows best in partial shade inland and full sun at the coast.  Supplemental irrigation is recommended to give this adaptable shrub a fuller, fresher appearance.  Combine it with toyon, coffeeberry, and oaks in a woodland garden; or mix with hummingbird sage, western columbine, and western meadow rue.

Salvia apiana (White sage):

Plant Type: Evergreen subshrub

Light: Sun

Soil: Adaptable; well-drained preferred

Water: Drought tolerant to occasional

Bloom Season: Spring to summer

Natural Habitat: Dry slopes and flats in coastal scrub chaparral, and some woodlands and forest below 4500 feet

Garden Usage: Hillsides, focal points, fragrance

 

White sage has something for everyone.  Gardeners treasure this strikingly handsome shrub for its bold foliage, dramatic floral display, and powerful scent.  It grows 2 to 3 feet tall and 3 to 6 feet across.  In spring it sends up flower stalks that easily add another 2 to 4 feet in height.  The lavender-tinged white flowers are clustered in interrupted spikes and the broad silvery white leaves are 3 to 4 inches long, with an incredibly pungent scent. An exceptionally drought-tolerant plant, white sage doesn’t need summer water and if over-watered in summer it may not survive.  It makes an arresting focal point in a border and can be massed on slopes to help curb erosion.  Prune the flower stalks back to the most robust new buds to keep the plant from becoming leggy.  Combine it with other sages, buckwheats, penstemons, ceanothus, and California fuchsias.  Bees produce a delicate and flavorful honey from its flowers.

Salvia clevelandii ‘Winifred Gilman’ (Cleveland sage):

Plant Type: Semi-evergreen shrub

Light: Sun

Soil: Well-drained

Water: Drought tolerant to occasional

Bloom Season: Late spring to summer

Natural Habitat: Dry slopes in coastal scrub and chaparral below 300 feet, garden hybrid

Garden Usage: Attracts hummingbirds, containers, herb gardens, dry border, fragrant

 

Evergreen shrub with flowers lavender to blue. This Cleveland sage is native to dry slopes San Diego County. It likes sun and perfect drainage. The gray-green leaves have intense fragrance.  The stalks of purple-blue flowers are spectacular during the blooming cycle, but also distinctive after the bloom when the seed pods turn a dark rusty brown.  The Salvias are great hummingbird plants. Plant them in the hottest, driest, fastest-draining site available.  They can be used as a focal point in a decorative pot, herb garden, or in a dry border as a low hedge.  Try planting Cleveland sage in front of island bush poppy and behind red-flowered buckwheat, foothill or royal penstemon, and groundcover manzanitas.  You can trim it back after fall for new spring growth.

Salvia leucophylla (Purple sage):

Plant Type: Semi-evergreen shrub

Light: Sun

Soil: Adaptable

Water: Drought tolerant to occasional

Bloom Season: Spring to summer

Natural Habitat: Common on dry, open hills and slopes in coastal scrub and chaparral below 2000 feet

Garden Usage: Sunny steep slopes, desert themed gardens, attracts hummingbirds, bumblebees, and wasps

 

Purple sage is a showy silver-leaved shrub with pungent fragrance and light-purple flowers in dramatic spikes. It forms neat mounds 5' tall and 6' wide.  Sages take full sun and are drought tolerant, although you can encourage blooming by giving them extra water, but be sure to let the ground dry out between watering and be careful not to give too much summer water. In California, the sages are visited by hummingbirds, bumblebees, wasps and bees.  If you want to keep the sage neat, you can prune it, but wait until it is not flowering.  Also makes an excellent low hedge.

 

 

Salvia leucophylla hybrid: (Purple sage hybrid):

Plant Type: Evergreen subshrub

Light: Sun

Soil: Adaptable; well-drained preferred

Water: Drought tolerant to occasional

Bloom Season: Spring to summer

Natural Habitat: Dry slopes and flats in coastal scrub chaparral, and some woodlands and forest below 4500 feet, garden hybrid

Garden Usage: Hillsides, focal points, fragrance

 

 

 

This variety is a very special hybrid of white and purple sage grown by our good friend Tom.  Its leaves have the appearance of a white sage but the flowers are light purple.  As with all sages, it’s important not to over water once they are established.  This has an incredible scent!  Can grow 6-8 feet tall and wide.  Ok to prune back after bloom period.

Vitus californica ‘Rogers Red’ (California Wild Grape):

Plant Type: Deciduous vine

Light: Sun to part shade

Soil: Adaptable

Water: Occasional

Bloom Season: Fall color

Natural Habitat: Garden hybrid

Garden Usage: Cover fences, arbors, trellises

 

Selected by Roger Raiche at the U.C. Berkeley Botanic Garden, this cultivar is now thought to be a natural hybrid between the native Vitis californica and the European wine grape, Vitis vinifera. A vigorous vine growing 3-6 feet per year, it turns flaming red in the fall before losing its leaves. Also sets fruit profusely, with only occasional water. While tasty, the grapes are seedy, making it better for birds than people. We have not found it to be messy, hanging onto the grapes until they are raisins, then picked off by birds.
