    Choose plants rated to Zone 10 or 11, and give tender ones shade in the afternoon.

    No winter rest

    Plants that need a cold winter to flower, like lilacs and tulips, won't perform here.

  4. 4

    Mulch and water deeply

    Mulch keeps the soil cool and holds moisture through long dry spells.
