Portulaca grandiflora, also known as purslane, dragon whiskers, peony, grass rhododendron, golden-thread rhododendron, etc., is also often called "can't die," because when people pick its fresh, juicy, fleshy stems and leaves and expose them to the sun, even though they lose water and wilt, they still do not die, and cuttings can still take root. The flowers grow at the tips of the branches and can reach 5 cm across, with single, double, and semi-double forms. The flower colors are rich, including white, white with red dots, pale yellow, deep yellow, bright red, deep red, and purple-red, and some are inlaid with patterns of several colors. Except for the first two, whose stems are green, the rest are light
