Heat-Tolerant Flowers
Portulaca (moss rose) is among the showiest and easiest of these types to grow. Both single and double forms produce blooms of many brilliant hues. Portulaca adapts to poor soil, and reseeds easily. Lantana thrives and flowers well in hot conditions, even growing in the narrow spaces between concrete and brick sidewalks. Gazania blooms freely throughout summer, thriving on heat and drought. It’s very effective in rock gardens. Among other flowers that tolerate hot and dry locations: gaillardia, periwinkle, anthemis, yarrow, California poppy, red flax, candytuft, African daisy (arctotis) and calliopsis.
