Arctostaphylos 'Howard McMinn' (Manzanita) - A medium-sized, evergreen mounding shrub to 7 to 10 feet tall by as wide with a densely-branched structure - can be kept smaller by pruning. It has beautiful smooth dark red bark and narrow 3/4 to 1 1/2-inch-long shiny green leaves and from late winter into spring appear intensely showy clusters of many small white flowers, tinged with light pink.
Plant in full sun to light shade. Though it requires little irrigation in coastal gardens, this plant can tolerate occasional watering, even applied overhead, which makes it both drought and garden tolerant. It is hardy to 0-10 degrees F. This cultivar is considered by most to be one of the most dependable and adaptable of the manzanitas - what they called "without a doubt, everyone's manzanita" in California Native Plants for the Garden by Carol Bornstein, David Fross and Bart O'Brien. It can be grown in sandy or heavy soils on the coast in full sun and in inland gardens with some shade.
This cultivar is often erroneously listed as a cultivar of the rare Vine Hill Manzanita, Arctostaphylos densiflora, which is a smaller growing pink flowering species with a very restricted natural range near Sebastopol in Sonoma County. Current though it that this plant is definitely of hybrid origin and initially thought possibly a hybrid between Arctostaphylos stanfordiana and A. densiflora because these two species are found in this same Vine Hill area, but the there is a good possibility that several other manzanita species such as Arctostaphylos bakeri and A. manzanita might also be involved in this hybrid. 'Howard McMinn' was first introduced by the Saratoga Horticultural Foundation in 1955 from plants given to them by Howard McMinn, the native plant author and Mills College Botany Professor. McMinn had cultivated a group of Arctostaphylos seedlings on the Mills College campus in Oakland from seedlings he had received from nurseryman Louis Edmunds in the spring of 1949 and he later suggested that the Saratoga Horticultural Foundation test these seedlings out. Besides the plant that was later named for McMinn, the cultivars 'Sentinel' and Harmony were all introduced from these seedlings, with 'Howard McMinn' becoming the most popular and later receiving the Award of Merit from the California Horticultural Society in 1956. The Saratoga Horticultural Foundation originally described it as a low shrub, growing to 5 feet tall, but in the half century since its introduction, it has become apparent that this plant can reach twice this height. We have grown it at our nursery since 1982.
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.
The information about Arctostaphylos 'Howard McMinn' displayed on this web page is based on our research conducted in the nursery's horticultural library and from reliable online resources. We also include 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 we receive from others and welcome hearing from anyone with additional information, particularly if they can share cultural information that would aid others in growing this plant. |
