Ceanothus griseus var. horizontalis 'Yankee Point' (Yankee Point Ceanothus) -This fast-growing, durable groundcover typically reaches 2 to 3 feet tall and spreads 8 to 12 or more feet wide but plants spaced too close together or among other plants can climb higher. Plants bear 1 1/2 inch long, glossy, dark green leaves and bright blue flower clusters in winter through early spring.
Plant in full coastal sun or shade. Despite its coastal origins, ‘Yankee Point’ will grow inland with no watering once established when sited in partial shade. Especially effective as a large-scale groundcover where salt-laden ocean spray is a factor. Hardy to about 15° F. Plants typically mound up to 5 feet tall if planted too close together. Judicious pruning is recommended to maintain a dense form and promote vigor.
By far, the most commonly planted selection of ceanothus in California and distinct from the Ceanothus griseus var. horizontalis form called "Carmel Creeper" which has slightly larger paler leaves and lighter blue flowers but unfortunately these plants have long been confused in the nursery trade as some felt them the same or at the least interchangeable. In side by side plantings at our nursery 'Yankee Point' proved more durable and attractive. While we continue to grow both 'Yankee Point' is by far the most popular cultivar.
, Ceanothus griseus var. horizontalis 'Yankee Point' was selected in 1954 by Maunsell Van Rensselaer, then the director of the Saratoga Horticultural Foundation which he co-founded in 1950 and previosuly the director of the Santa Barbara Botanic Garden. Van Rensselaer chose the lowest growing, most floriferous, and darkest flowered individual from his original collection of four plants that came from Yankee Point, a rocky, exposed bluff in northern Monterey County.
The varietal name "horizontalis" for this form of Ceanothus griseus was described in 1942 by Howard McMinn when he found it growing on wind swept bluffs in Monterey County but recent treatment has included this species as a variety of Ceanothus thyrsiflorus, as American botanist William Trelease originally described it in 1897. This makes the correct name for this plant Ceanothus thyrsiflorus var. griseus 'Yankee Point', but we will continue to list this plant under the older name, as we have since 1981, until this new name becomes more widely accepted.
The genus name comes from the Greek word keanthos which was used to describe a type of thistle and meaning a "thorny plant" or "spiny plant" and first used by Linnaeus in 1753 to describe New Jersey Tea, Ceanothus americanus. This older specific epithet (now the variety) is from the Latin word 'grise' meaning gray, possibly referring to the undersides of the leaves with the new epithet referring to flowers being in a thyrse or multiple branching.
The information about Ceanothus griseus var. horizontalis 'Yankee Point' 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. |
