In Santa Cruz and coastal areas down to Los Angeles and San Diego, rock purslane, Calandrinia spectabilis (grandiflora) has been popular for only a few years. It is still somewhat uncommon here in the Santa Clara Valley. Because of the ambiguity of its Latin species name, it is most  commonly known simply by its genus name of Calandrinia.

Moderate watering is best. On the coast, rock purslane only needs water occasionally through the driest summer weather. It should recover readily from winter frost damage. Partial shade is not a problem, but may limit profusion of bloom. Harsh exposure or reflected glare can actually roast the tender succulent foliage.

From about now through autumn, limber, two foot tall stems suspend strikingly bright magenta flowers above the low, grayish evergreen foliage. The fragile leaves are neatly arranged in terminal rosettes. Foliage, stems, flower stalks and all parts are sensitive to traffic, and can even get broken by a cat sneaking through the garden. Broken bits and pieces of stem root very easily to make new plants, though.
