A broadly spreading shrub, fast growing for a manzanita, eventually forming a good dense ground cover 1.5 - 2.5 ft. tall by 10 ft. wide. Handsome gray-green leaves with deep reddish-brown bark. Small clusters of white urn-shaped flowers in late winter are pretty, but it is not a heavy bloomer. This fine introduction from Rancho Santa Ana Botanic Garden is proving to be dependable and disease resistant. Plant in sun or light shade. More drought tolerant than the popular bearberries. In cool summer areas may need no additional summer water once established. In hotter inland sites,occasional deep summer waterings is best. It is believed to be a cross involving the rare Bonny Doon manzanita.
Arctostaphylos cruzensis
This rare, low-growing manzanita comes from the San Luis Obispo coast. Features grey-green, wedge-shaped leaves and soft pink flowers in the winter. Its distinctive creeping habit makes it ideal for crawling over walls or lining walkways. Provide full sun to light shade and moderate to infrequent irrigation once established. Good in containers.
Arctostaphylos edmundsii ‘Bert Johnson’
Choice, low growing manzanita introduced by the Tilden Botanic Garden. Dense, mounding or cascading habit growing to around a foot tall by 6 ft. wide with small dark green leaves and bronzy new growth. Not as fast growing as 'Carmel Sur'. Clusters of tiny pink to white urn-shaped flowers in winter attract hummingbirds and are followed by handsome cinnamon colored little apple-shaped fruits. Excellent cascading over walls, rocks, or containers in sun to light shade. This manzanita has proven adaptable and fairly garden tolerant putting up with heavy soils and more summer water than many. Full sun along the coast with light shade in hot inland sites. Drought tolerant once established but appreciates occasional summer water.

Arctostaphylos franciscana
This distinctive clone of the very rare franciscan manzanita displays luxuriant growth of shiny, dark green leaves spreading fairly quickly to form a dense drift up to eight ft wide and 2 - 3 ft tall. An excellent groundcover similar in appearance to A. uva-ursi but more drought tolerant and somewhat taller. A good manzanita for serpentine but still does well in other soils. Produces a modest display of pinkish white flowers in winter. Plant in full sun but light shade is fine especially in hotter climates. Requires moderate to occasional irrigation once established.
Arctostaphylos glandulosa f. repens ‘Mount Vision’
Found only in the Bishop pine forest of the Point Reyes Peninsula, the repens form has a low and mounding habit. This particular selection was picked for its exceptionally compact and creeping nature and large, gray-green leaves. Clusters of white flowers hang from branch tips in early winter. While slower growing than most other groundcover manzanitas, this cultivar will eventually reach about 6 ft wide with a height of about 1 ft. 'Mount Vision' is best planted as a specimen rather than in mass plantings. Very drought tolerant once established with full sun to light shade. An excellent container plant.
Arctostaphylos hookeri ‘Harry Roberts’
A dense and low selection of this hardy and adaptable species, reaching to about 1 foot tall and around 6 ft wide. Not quite as short as ‘Monterey Carpet’, but a little faster growing. The deep green, pointed leaves create a verdant groundcover, suitable for drier spots. The small, white flowers in winter are not particularly abundant. Plant in full sun to light shade and water infrequently. Clay soil tolerant. A great, low growing manzanita for hotter areas. This species is a rare native from coastal Monterey and Santa Cruz Counties.
Arctostaphylos hookeri ‘Monterey Carpet’
Evergreen, creeping manzanita less than 1 ft. tall with small, deep green leaves. Dark red branches tend to root and increase its spread to 8 ft. or so wide. Small clusters of white flowers appear in late winter to early spring. Prefers a little shade inland. Drought tolerant but enjoys occasional irrigation in inland sites. Perfect under deciduous oaks or tall pines. Works well in spots where the creeping branches can spill over an edge, creating a cascade effect.
Arctostaphylos hookeri ‘Wayside’
A robust selection of the Monterey manzanita with dense branches growing up to 3 ft. high by 8 ft or more broad. Attractive upsweeping crooked trunks with little white flowers and small deep green leaves. Occurring on open hills around Monterey Bay. Despite its somewhat coastal origin, this selection tolerates, sun, heat and drought quite well. That being said, it will also accept occasional irrigation and light shade. A very useful plant for covering large sunny banks with poor soil.
Arctostaphylos montana ssp. ravenii
This diminutive, groundcover manzanita once grew on windswept, serpentine outcrops in San Francisco where the Presidio currently exists. Due to rapid development in the late 19th and early 20th centuries, only one clone of this manzanita currently exists in the wild, making it one of the rarest species around. The small, thick, gray-green leaves line creeping stems reaching 6 - 12 inches in height. Forms a large mat over time, crawling around rocks and other obstacles. In late winter/early spring, clusters of little, white, urn-shaped flowers appear at the ends of the stems. Needs full sun to light shade and decent drainage. Drought tolerant once established but will enjoy an occasional deep watering, especially in warmer areas. You don’t have to be a collector to enjoy this appealing little manzanita.
