California lilac, also known as Ceanothus, is a flowering shrub native to California and other parts of the western United States. It typically blooms in spring, producing clusters of small, vibrant blue or purple flowers that attract pollinators like bees and butterflies. The plant is drought-tolerant and thrives in well-drained soils, making it a popular choice for gardens in arid regions. This shrub can vary in size, ranging from low-growing ground covers to taller varieties that can reach up to 10 feet in height. California lilac is often used in landscaping for its ornamental value and ability to provide habitat for wildlife. Its resilience to dry conditions makes it an excellent choice for sustainable gardening.
