Saint John’s wort is the common name of a few species of Hypericum. Hypericum beanii sometimes gets the distinction of Bean’s Saint John’s wort. That sounds more like carob, Ceratonia siliqua, though. Carob is the locust bean that sustained Saint John the Baptist in the desert. Mr. Bean was actually a respected botanist of the Royal Botanical Garden.

This Saint John’s wort is not as invasive as naturalized sorts, but is as resilient. Although rarely available from nurseries, it survives in old and neglected landscapes. Established specimens need no irrigation, but perform better with it. This species is likely rare merely because of its resemblance to invasive sorts. It propagates quite efficiently from cuttings.

Hypericum beanii is a shrubby species, unlike more familiar ground cover types. It grows about two or three feet tall and wide. Its bright yellow flowers are about two inches wide, and bloom through summer. Foliage is deciduous where winter is cooler. Here, it is likely to linger until spring foliage replaces it. Partial shade is tolerable, but might inhibit bloom.
