Japanese Maples: Autumn Fireworks for Mild Climates

Japanese maples (Acer palmatum) steal the show in autumn, when clear skies and cold nights set their leaves ablaze in gold, orange, red, and yellow. These airy, delicate trees thrive in mild summers and cool winters, making them especially at home along the Pacific Coast from British Columbia to Northern California.

In milder parts of Southern California and high desert areas, fall color may be less intense, but gardeners can succeed by providing filtered shade, wind protection, and occasional deep watering to leach salts from the soil.

Any Japanese maple makes a graceful accent in gardens, containers, or as pruned branches in holiday arrangements. They grow in Sunset climate zones 2–10, 12, 14–24—everywhere except hot low deserts and the coldest-winter areas.
