Zone 10 is one of the warmest USDA planting zones, with average minimum winter temperatures ranging from 30°F to 40°F. This subtropical-to-tropical climate is ideal for plants that thrive in heat, humidity, and year-round sunshine. With such favorable conditions, Zone 10 gardeners can grow an incredible variety of tropical foliage, flowering shrubs, and palm trees. 

Flowering plants are especially popular in Zone 10, with hibiscus, plumbago, oleander, dipladenia, and mandevilla vines bringing vibrant color throughout the year. These shrubs and vines thrive in warm soil and respond well to full sun. For lush foliage, Zone 10 is home to tropical giants like alocasia, crotons, monstera, and bird of paradise. These bold plants add structure, texture, and an exotic feel to both landscapes and indoor spaces. Gardeners also enjoy palms such as majesty palm, Chinese fan palm, and roebellenii palm, which perform exceptionally well in the heat. 

Because frosts are extremely rare in Zone 10, many plants here grow larger and bloom longer than they would in cooler climates. This makes Zone 10 a true paradise for gardeners who want bold landscapes, outdoor tropical gardens, or year-round patio plants.
