This Beautiful hybrid lilac grows to only about 3-5 ft high but about 8-12 ft wide. 'Joyce Coulter' has dark green foliage and medium blue flowers which bloom all the way from March to May. This variety will tolerate pruning and a wide range of garden conditions. It is fast-growing and is a beautiful choice for large slopes, or above a retaining wall, or anywhere you want a low-water yet lush flowering plant. Due to the width of this plant you can cover large areas with just a few plants. It grows well in hot areas and is drought tolerant.
It is a natural hybrid of
Ceanothus papillosus
var. roweanus x
Ceanothus impressus
(possibly) and was introduced by the saratoga Horticultural Foundation in 1956. Tolerates almost any soil type. Prefers sun in coastal sites, and sun or part shade in inland sites. Selected by John E. Coulter in san Carlos, CA in 1956; introduced by saratoga Horticultural Foundation in 1962. possible hybrid of C. papillosus x C. thyrsiflorus var. griseus.
