Ceanothus impressus var. nipomensis, commonly known as Nipomo Ceanothus or Nipomo Lilac, is a perennial shrub native to the coastal sage scrub and chaparral regions of California, particularly in San Luis Obispo County. It typically grows at a moderate rate to a height and width of 3-6 feet (0.9-1.8 meters). This species is characterized by its dark green, holly-like leaves and clusters of intense blue flowers that are particularly showy in the spring. The flowers are highly attractive to pollinators such as bees and butterflies.

Nipomo Ceanothus is valued for its drought tolerance and ability to thrive in poor soils, making it an excellent choice for water-wise gardens and native plant landscapes. It is often used for slope stabilization, habitat restoration, and as an ornamental shrub in residential gardens. This ceanothus prefers full sun to part shade and requires very little water once established, reflecting its adaptation to the dry California climate. It is important to avoid overwatering and to provide well-draining soil to prevent root rot. While generally low-maintenance, it can be susceptible to fungal diseases if conditions are too wet.CC BY-SA 4.0
