I just purchased and planted in the garden the newest introduction of Ceanothus or California Lilac "Tuxedo". The beautiful powder blue flowers when it blooms this coming Summer will be outstanding against the very dark purple/black evergreen foliage. The Ceanothus is a wonderful plant for a drought tolerant gardens. This is the fifth Ceanothus I have planted. All gardens should have at least one variety of this plant, mason bees will love you for it. If you come across this plant pick it up, I purchased my at Garden Fever located at 3433 NE 24th Ave.
Tuxedo is an upright selection with an open well branched habit. It responds well to pruning and will make a dramatic garden specimen. A summer blooming variety with lavender blue flowers that will grow to approximately 8' tall by 8' wide. Plants will bloom sporadically through warmer months but reach their full flowering potential in late summer to fall. USDA hardiness zone 8 to zone 10.
