We have two varieties of Ceanothus. Centennial is a plant we’ve had in the yard for years and are one of the few plants we left in when we started the landscaping. Now we have ten more. It’s a low-growing (less than 2 ft) spreading plant with dark green leaves and purple flowers.
Dark Star will get 4-8 feet tall and is a tougher, more spindly plant. It also has gorgeous purple flowers. Both plants are used by birds, bees, and butterflies.
