Helping You Become a More Successful Gardener

Long before these California natives caught on out west, the English developed ‘Cascade’ in 1938, the first hybrid suited to the rainy, cool climate of Great Britain. It is believed to have come from Ceanothus thyrsifolius, which shares an enormous range from Santa Barbara to Oregon. This upright shrub produces small dark glossy green leaves with a unique wrinkled surface.
‘Cascade’ blooms heavily mid to late spring with clusters of tiny blue flowers at the branch tips. Due to the origins of its parent along the coast, it may not perform as well further inland. California lilac will grow in heavier soils but only when exceptionally well drained, typically on slopes gentle and steep. In the wild they prefer the sheltered canyons as well as oak and pine woodlands where it adapts to acidic soils.
Grow ‘Cascade’ in full sun on the coast but protect from direct afternoon sun further inland. It is ideal for soils around oak trees where excessive summer water can be problematic. Provide deep irrigation the first year or two after planting to ensure deep rooting, then wean summer water to an occasional deep soaking in year three.
