Kiss-me-quick (Portulaca pilosa) —
Also known as Pink Purslane, Kiss-me-quicks are native succulents that can be used as a groundcover. They will thrive in nutrient-poor soil as long as it is well-drained. These low-growing plants with linear leaves produce red, pink, or purple blooms in the morning that close in the afternoon, hence the name Kiss-me-quick.
Look for Kiss-me-quicks in the wild in sunny, sandy areas.
