Portulaca, or moss rose, is a popular drought-tolerant annual. Plants are low-growing spreaders with thick succulent stems and vibrant, cup-shaped flowers. Flowers come in a wide range of colors. Portulacas love it hot and dry. You can plant them in poor, even sandy, soil. They also adapt to average garden conditions. Just give them full sun and any well-drained soil. Moss roses don’t need much care. Water them after planting and watch them go. They’ll grow 4 to 8 inches high and spread 6 to 18 inches. You don’t even have to deadhead. If plants get scraggly, you can cut them back. Don’t fertilize too much; it will encourage plants to produce thick foliage but fewer flowers. All portulacas need sun for their flowers to open. The flowers of older varieties closed up around noon. But most plants sold today have blooms that stay open all day. They stay closed at night and on cloudy days.
