Can you suggest some drought-friendly flowers?
You're wise to site plants with similar water needs together. Many gardeners run into trouble when neighboring plants require very different care. There are many good plants for your sunny garden. Some of the most popular annuals that resist drought and bloom in shades of red, yellow, and orange include annual salvia (Salvia splendens and S. coccinea), marigold (Tagetes erecta, T. patula, and T. tenuifolia selections), melampodium (Leucanthemum paludosum), creeping zinnia (Sanvitalia procumbens), zinnia (Zinnia elegans, Z. angustifolia, and Z. haageana), moss rose (Portulaca grandiflora), annual vinca (Catharanthus roseus), gazania (Gazania), and cockscomb (Celosia).
