Hardiness Zone 10
USDA Hardiness Zone 10 has average annual minimum winter temperatures of 30°F to 40°F (-1.1°C to 4.4°C), allowing gardeners to grow an exceptional range of subtropical, Mediterranean, and warm-climate plants. From dramatic flowering trees and colorful shrubs to long-blooming perennials, Zone 10 offers possibilities that colder regions can only enjoy as summer plants.
The key is choosing plants suited not only to winter temperatures, but also to your garden’s sun, soil, moisture, heat, and local climate.
What grows well in USDA Zone 10?
Zone 10 supports an unusually broad plant palette. Depending on your location, you can grow tropical-looking foliage plants, flowering shrubs, drought-tolerant Mediterranean species, palms, succulents, warm-climate perennials, and many plants that must be overwintered indoors in colder zones.
Winter hardiness is only one part of plant selection. Coastal exposure, summer heat, humidity, rainfall, soil drainage, and water availability can all influence which Zone 10 plants will perform best.
Best trees and shrubs for Zone 10
Trees and shrubs can give a Zone 10 garden year-round structure, shade, privacy, flowers, and foliage color.
- Trees: Royal Poinciana (Delonix regia), Monkey Puzzle (Araucaria araucana), and Strawberry Tree (Arbutus unedo).
- Shrubs: Hibiscus, including tropical hibiscus (Hibiscus rosa-sinensis), Bougainvillea (Bougainvillea spp.), and Oleander (Nerium oleander).
Best perennials and flowers for Zone 10
With such mild winters, many plants that behave as annuals farther north can remain evergreen or return year after year in Zone 10.
- Perennials: Bird of Paradise (Strelitzia reginae), Agapanthus (Agapanthus spp.), and many bromeliads (Bromeliaceae).
- Warm-season and bedding flowers: Wax Begonia (Begonia semperflorens group), Sunflower (Helianthus annuus), and Gazania (Gazania spp.).
Choose plants for your part of Zone 10
Two gardens in Zone 10 can have very different growing conditions. A humid South Florida garden, a dry Southern California landscape, and a coastal garden may share the same USDA hardiness zone while requiring very different plants.
Whenever possible, favor plants adapted to your regional climate and growing conditions. Native plants can be particularly valuable because locally appropriate species often support native pollinators, butterflies, birds, and other wildlife while requiring fewer inputs once established.
Look beyond hardiness before planting
A Zone 10 rating tells you whether a plant should tolerate your typical winter minimum temperatures. It does not tell you whether the plant will enjoy your summer heat, humidity, soil, rainfall, or exposure.
For the best results, compare each plant’s requirements for sunlight, drainage, water, mature size, and heat tolerance before adding it to your garden.
