Ceanothus Ray Hartman ~ California Lilac

Ceanothus Ray Hartman is a large robust shrub or even a small tree. Ceanothus Ray Hartman can grow to 20 feet in height and will typically be half that width. Ceanothus Ray Hartman will produce its blue flowers in the Early Spring, March in our area. The plants do best with little summer water. Ceanothus Ray Hartman is the result of a cross between Ceanothus griseus and Ceanothus arboreus. Plants will survive longer if they are kept pretty dry once they have been established. I prefer to plant them on a slope or in well drained soil. Ceanothus Ray Hartman is a host plant for the Western Tussock Moth Caterpillar, Hedgerow Hairstreak, and the Pale Tiger Swallowtail and is an early season nectar source for the Spring Azure and Monarch Butterfly.
