Bees, Butterflies, and Birds Love the Blue Blossoms

  • Attracts Butterflies, Bees, and Birds
  • Marvelous Clusters of Blue Blossoms
  • Easy to Grow and Maintain

You haven't seen how lovely blue can be until you've seen a Ray Hartman California Lilac (Ceanothus 'Ray Hartman') in full bloom. When this broadleaved evergreen shrub is covered in puffy clusters of blue flowers, you will understand why Ray Hartman, one of the founders of the Saratoga Horticultural Foundation, lent this tough shrub his name after discovering it in his garden in the 1940s.

When late winter and early spring comes around, you'll be in for a real treat. The Ray Hartman California Lilac bursts with 6-inch spikes covered in petite blue flowers, which add a bit of romance and whimsy to your garden.

And don't be surprised to see winged wildlife stopping by for a nectar treat. These flowers are quite alluring to bees, birds, and butterflies. With all the attention this plant will get from pollinators, your garden ecosystem is sure to thrive.

Even when not in bloom, this plant's leaves still fill any landscape with rich color. They grow to be about 6 inches and are a deep, glossy green. They also have a lovely ridged texture that creates a hardy appearance and brings a welcomed layer of interest.

Leave the lower branches on for a pretty privacy screen. Or, carefully prune this bushy shrub into a lovely, multi-trunked tree. Plant one where you'd like a little shade or where you can sit and watch the butterflies flutter by. This beauty would also make a great addition nearby or to add height in your butterfly garden.

This plant is drought tolerant and requires little maintenance once established. So, you will have plenty of time to tend to the rest of your garden or relax with a cup of tea and watch what birds stop by for visit.

This floriferous shrub will add a sense of calm and tranquility to your landscape. Order several to create your corner of paradise with help from Nature Hills today!
