Portulaca (moss rose) is native to hot, dry plains in South America, and it shows: this is a good summer annual for the driest, sunniest, most neglected corner of the garden, not a plant that needs coddling. It forms a succulent, 4- to 8-inch mat studded with rose-like or single cup blooms in bright pink, orange, yellow, red, or white.

How portulaca (moss rose) fits zone 11's season
