Ceanothus “Tilden Park” is a small-leafed, very shrubby, overly bloomful local variety.
This Wild California Lilac is a late bloomer for the California Lilacs, lasting into early summer. Can handle full sun, and even the inland heat, or the coastal fog belt. Can tolerate poor soils, as long as it has good drainage. Great for large swaths of the hillsides. Attracts native bees.
Easy to prune, but make sure you prune in spring before the blooms.
