Description

Yankee Point Ceanothus is one of the most garden adapted selections from our native wild lilac plant group. It shows good performance throughout the Inland Empire in locations that are protected from hot afternoon summer sun. It grows best in well drained conditions and with periodic deep watering during the summer.

This popular native shrub is a good option for slopes, parkways and large garden spaces where it can grow to 3 ft. high and 10-12 ft. across. It has a sprawling branching structure that reach outward and upward in habit. It has handsome oval dark green leaves and produces numerous powder-blue flowers in 1-2 in. long clusters in spring. In contrast to its natural growth habit, this cultivar can be clipped and pruned to maintain a more uniform and regular shape.

Water Needs

Yankee point wild lilac is well adapted all parts of the Inland Empire moderate amounts of supplemental water; however, periodic deep watering in summer is recommended over weekly watering. The chart shown below provides a recommended baseline guide to the monthly irrigation schedule and volume of supplemental water needed to maintain healthy growth throughout the average year. It should be noted there are several months marked by an asterisk (*) when winter rains can provide sufficient moisture and irrigation is not needed. The high and low range of moisture indicates it can grow with varying amounts of water; manage summer water to allow leaf litter and the understory of this plant to dry out between waterings to reduce the risk of disease problems.

Maintenance

Prune by heading back as much of the new-ish growth as desired in April or May, after flowering. Further prune in the same way, if desired, in November. New growth over the cool season will have time to develop flower buds for spring. Ceanothus are browsed by Deer. Think like you are a deer having a snack with your pruners. By mid-winter it is too late to prune or you will be removing the growth that would form the flower buds that will bloom in Spring (1). Older branches often do not react well to pruning, so it is better not to prune any branches greater than the diameter of a pencil (7).
