Plant in full sun to light shade and give little to occasional irrigation. Hardy to around 5 degrees F. This manzanita has proven to be a durable long-lived shrub that can be planted in a wide range of conditions. Unlike many other shrubby cultivars, it has shredding brown bark that is mostly hidden beneath the dense foliage.

This plant was discovered in 1965 by Roman Ganklin and W. Richard Hildreth in chaparral near Prunedale in Monterey County while on a plant collection trip for the UC Davis Arboretum. The plant was noted to exhibit characteristics intermediate between Arctostaphylos pajaroensis and A. hookeri, the two species growing at this location. It had the shredded bark typical of A. pajaroensis and glossy pointed leaves and hairy new branches of A. hookeri. Cuttings of it were rooted and planted at the arboretum and plants were shared with the Saratoga Horticultural Foundation where it was trialed and released with the name commemorating the 75th anniversary of Sunset Magazine in 1973.

The name Arctostaphylos was given to the genus by the French (of Scottish descent) naturalist Michel Adanson (1707-1778), who first named the circumboreal Arctostaphylos uva-ursi for plants found in Europe. The name comes from the Greek words 'arktos' meaning "bear" and 'staphyle' meaning "grapes" in reference to bears eating the fruit and the common name Bearberry also references this fact. 

This information about Arctostaphylos 'Sunset' displayed is based on research conducted in our horticultural library and from reliable online resources. We also will relate observations made about it as it grows in our nursery gardens and other gardens we have visited, as well how the crops have performed in containers in our nursery field. We will also incorporate comments that we receive from others and we welcome hearing from anyone with additional information, particularly if they can share any cultural information that would aid others in growing it.
