Planting Zones 12 and 13 are not found in the continental United States,
but are restricted to coastal areas of Hawaii and Puerto Rico. The climate is
hot and tropical with warm winters and no frosts. The key is to pick vegetables
and herbs that can tolerate extreme heat in summer. The focus is on tropical plants.
Almost all vegetables can be grown in Zones 12 by simply planting during cooler months
and by using shade and irrigation to reduce the threat of heat damage. Vegetables
planted in late summer early will bring a harvest in late June or early July. Plants
that are heat and drought tolerant and have a short growing season, suitable for this zone include:
Hot peppers
Summer squashes, Bush beans, Eggplant, Tomatoes, Borage, Cilantro, Rosemary, Sage
