Ceanothus impressus 'Vandenberg' (Vandenberg Ceanothus) - A densely compact shrub growing 3 to 6 feet tall by 5 to 8 feet wide with tiny, dimpled, deep green leaves and bright blue flowers in spring. As with other selections of this species, plants prefer well-drained soils and are best suited to coastal gardens, where they require little to no water in summer. Although less dramatic than the closely related ‘Dark Star’ and ‘Julia Phelps’ when in bloom, its fine texture, compact shape, and lighter blue flowers make ‘Vandenberg’ a solid addition to the stable of wild lilacs. It is hardy to about 10 degrees F. Selected by M. Nevin Smith in the 1982 from Vandenberg Air Force Base in Santa Barbara County. There are possibly other so-named plants in the California nursery trade. Monterey Bay Nursery lists a Ceanothus impressus 'Compact Vandenberg' and Native Sons Nursery describes Ceanothus impressus 'Vandenberg' as a selection that Austin Griffith made from Burton Mesa. 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. The specific epithet is from the Latin word 'impress' meaning "sunken" or "impressed" in reference to the veins on the leaves.  The information on this page is based on the research that we have conducted about this plant in the San Marcos Growers library, from what we have found on reliable online sources, as well as from observations made of our crops of this plant growing in the nursery and of plants growing in the nursery's garden and those in other gardens where we may have observed it. We also have incorporated 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 impressus 'Vandenberg'.
