June is the best month to start planting heat-loving annuals that thrive in full sun. Some of these annuals include Dianthus, Marigold, Caladium, Gaillardia, Zinnia, Celosia, Gazania, Portulaca, Vinca, and some Coleus.
Summer's warm, rainy months are also the perfect time to plant palms. Smaller palms include Christmas Palms, Areca Palms, and Pygmy Date Palms. Large palms include Coconut Palms, Foxtail Palms, Queen Palms, Royal Palms, and Bismarck Palms.
