USDA hardiness zone 10: plant guide

Zone 10 has winter lows of 30°F to 40°F — essentially frost-free. It covers South Florida (Miami, Fort Lauderdale, much of Palm Beach County), southernmost California (coastal Los Angeles, San Diego), and lower-elevation Hawaii. Growing happens year-round, but the seasonal pattern flips compared to colder zones: the cool dry winter is the most productive growing season for vegetables, while hot wet summers belong to mango, papaya, and ornamental tropicals.

Best plants for zone 10

Zone 10 hosts a near-tropical plant palette. Cold damage is rare but possible during a hard freeze event every 10-20 years. The lists below favor species that bounce back from a brief 30°F night without dying.

Perennials

Bird of paradise (Strelitzia reginae) — 3-5 ft, full sun, dramatic orange-and-blue blooms year-round in zone 10.
Heliconia (Heliconia rostrata) — 3-8 ft, part sun, pendulous red-and-yellow bracts.
Anthurium (Anthurium andraeanum) — 1-2 ft, shade, glossy red or pink spathes year-round.
Pentas (Pentas lanceolata) — 2-3 ft, full sun, year-round bloomer beloved by butterflies and hummingbirds.
Crinum lily (Crinum spp.) — 3-4 ft, sun to part shade, fragrant white or pink blooms; very drought-tolerant.

Shrubs

Hibiscus (Hibiscus rosa-sinensis) — 6-12 ft, full sun, dinner-plate blooms in a full color range.
Plumeria (Plumeria rubra) — 8-15 ft, full sun, intensely fragrant pink/ yellow/white blooms in summer.
Bougainvillea (Bougainvillea spp.) — 10-30 ft when vining, full sun, dazzling bracts.
Ixora (Ixora coccinea) — 4-6 ft, full sun, year-round red/orange/pink flower clusters.

Trees

Mango (Mangifera indica) — 30-50 ft, full sun, summer fruiting; the classic South Florida dooryard tree.
Royal palm (Roystonea regia) — 50-80 ft, full sun, signature avenue palm of South Florida.
Avocado (Persea americana) — 30-40 ft, full sun, fruits summer through winter depending on cultivar.

Vegetables and fruit

Winter is the vegetable season — October-April for tomatoes, peppers, lettuce, beans, squash. Summer is too hot and wet for most.
Heat-loving crops — okra, southern peas, sweet potato, malabar spinach, yard-long beans grow through summer.
Tropical fruit — mango, papaya, avocado, banana, guava, lychee, longan, soursop, sapodilla.
Citrus (where greening permits) — Meyer lemon, Persian lime, calamondin.

Frost dates for zone 10

Zone 10 is technically frost-free in most years, but radiational-cooling events still produce occasional light frost in inland low spots. Coastal zone 10 averages 0-1 frost nights per year; inland microclimates may see 2-3. Cold snaps are usually brief — a few hours below 35°F before warming.

When to plant in zone 10

September-October: Plant fall/ winter tomato, pepper transplants; direct-sow beans, squash, cucumbers, lettuce, brassicas.
November-December: Continue plantings of cool-season crops. Best window for trees, shrubs, perennials.
January-February: Last transplant window for tomatoes to mature before heat. Plant deciduous fruit trees (low-chill apples, peaches).
March-April: Plant okra, sweet potato slips, southern peas for summer.
May-August: Maintenance season. Plant heat-tolerant tropicals; harvest mango, avocado, summer vegetables.

Common challenges

Hurricanes and tropical storms:June-November in South Florida. Plant wind-tolerant species (royal palm, sea grape, gumbo limbo) and avoid brittle trees (Bradford pear, Norfolk Island pine).
Salt spray (coastal): Limits plant choice within ~100 yards of the ocean. Sea grape, beach sunflower, oleander, agave all handle it.
Sandy or alkaline soil: Most of South Florida sits on alkaline limestone — iron chlorosis is common on otherwise-healthy plants. Use chelated iron supplements.
Invasive species pressure:Brazilian pepper, Australian pine, Old World climbing fern crowd out native gardens. Aggressive removal is mandatory.

Recommended tools

Year-round planting needs continuous planning. The garden planner lets you sequence winter vegetables, summer tropicals, and ornamentals in the same beds. The plant spacing calculator helps with the airflow needed in humid zone-10 summers. The plant advisor suggests species filtered to zone 10.
