Pollination Info for Ray Hartman California Lilac (Ceanothus x 'Ray Hartman')

The Ray Hartman California Lilac is a hybrid of two Ceanothus species, Ceanothus arboreus and Ceanothus griseus. It is a popular ornamental shrub that produces clusters of fragrant blue flowers in the spring.

This particular cultivar is known for being self-fertile, meaning that it does not require another plant to pollinate it in order to produce fruit. However, cross-pollination can increase the quality of the fruit and yield a larger crop.

If you do choose to cross-pollinate your Ray Hartman California Lilac, it is recommended to plant another Ceanothus of a different cultivar or species nearby in order to increase the chances of successful pollination.

The best time to pollinate your Ceanothus is in the morning when the flowers are open and before the heat of the day sets in. You can do this manually by using a small brush or by allowing pollinators such as bees and butterflies to do the job for you.

Overall, while the Ray Hartman California Lilac does not require cross-pollination, doing so can have beneficial effects on fruit quality and yield.
