Baby blue flowers in late April to early June cover this nice, small tree. An Oregon native, 12' T x 6' W. Minimum temperature: -0°F

This is a selection from the northern part of its range in sw Oregon and has smaller deep evergreen leaves and masses of turqouise flowers in May-June. This loves a crummy well-drained soil where it quickly becomes a small nitrogen-fixing tree. Can be clipped to a big shrub but why create work.

One of the best new ceanothus introductions, this from near Cape Blanco on the Oregon Coast by plantsmen Paul Bonine and Greg Shepherd. Though originally thought to be rather diminutive, our plants have grown to nearly 10 ft in 3 years, so we now declare it a miniature tree adorned with delicate, 1/3” green glossy leaves and dusky blue flowers throughout the year in mild climates and especially in spring and fall with inland heat. When pruned into standards, the delightful green bark can be exposed, sure to elicit squeals of delight at your next open garden. Sun to light shade. Tolerant of some summer garden water but long lived and slower growing without water. Frost hardy to low USDA zone 8.
