Ceanothus thyrsiflorus "Zanzibar"
Planted out in the front garden by the street. When it blooms the powdery blue flowers are striking against the variegated foliage of green splashes on golden leaves. As you see it has a few blooms on it now.....Coldest November in 25 years and a few of the plants in the gardens are blooming. Have they lost their little minds, do they know what time of year it is. The majority of the species are evergreen, but the handful of species adapted to cold winters are deciduous with all species from North America. One of the best drought tolerant plants you can grow, you do not have to water them here. If you do water them you stand a chance of killing them. They do not like extra water of any kind, shape, or form. Some will live to 20 to 25 years if allowed to grow properly. A full sun exposure in well-drained to heavy clay soil. It will grow to a height of about 10' and as wide as 5'. I manicure mine so it does not take over and cover the smaller plants I have around it. I have other Ceanothus planted in other areas and they seem to do well on their without to much work. When they do go into a full bloom in the Spring the bees are thick on these plants, it is quite the show.
