  • A North American shrub of the buckthorn family, cultivated for its dense clusters of small blue or white flowers.

    • ‘Plants chosen for drought tolerance as well as color thrive here, including catmint (Nepeta ‘Blue Wonder’), ceanothus, lychnis, penstemon, purple coneflower, rockrose, rosemary, and star jasmine.’
    • ‘To distinguish a blue blossom ceanothus from a musk bush, for example, look for ridges on the plants' stems.’
    • ‘Take heel cuttings from ceanothus, penstemons, lavenders, santolinas and philadelphus.’
    • ‘It's a good time to thin out weak branches of ceanothus and to shorten remaining growths (not into old wood).’
