Ceanothus griseus var. horizontalis 'Yankee Point' (Yankee Point Ceanothus) – By far, the most commonly planted selection of ceanothus in California, this fast-growing, durable groundcover reaches 2 to 3 feet tall and spreads 8 to 12 or more feet wide. Plants bear 1 1/2 inch long, glossy, dark green leaves and bright blue flower clusters in winter through early spring. 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. This plant is 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 and so we only continue to grow this cultivar, which was selected in 1954 by Maunsell Van Rensselaer (past director of the Santa Barbara Botanic Garden), who 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 on this webpage is based on research conducted about this plant in our nursery library, from online sources, as well as from observations made of it as it grows in the nursery in containers, in the nursery's garden and in other gardens where we have observed it growing. We will also incorporate comments received from others and welcome getting feedback from those who may have additional information, particularly if this information includes cultural information that would aid others in growing  Ceanothus 'Yankee Point'.
