California Christmas Bush Plant Care

California Christmas Bush (Carpenteria californica) belongs to the Hydrangeaceae family within the Carpenteria genus. California Christmas Bush is native to the Sierra Nevada foothills in California. California Christmas Bush is also known as Bush Anemone.

California Christmas Bush displays an upright, spreading shrub growth habit, reaching up to 6 ft tall with a spread of approximately 4 ft. California Christmas Bush produces fragrant white flowers with yellow stamens.

Leaf size: approximately 4 inches.

Water a young or newly planted California Christmas Bush every 7–10 days, soaking the whole root zone, until it is established — usually one to two growing seasons. Established trees mainly need water during long dry spells. In a container, water whenever the top few centimetres of soil are dry.

California Christmas Bush thrives in full sun to partial shade.

Carpenteria californica tolerates temperatures of 50–80°F. California Christmas Bush prefers humidity levels of 40–70%.

Well-draining, acidic soil with high organic content. Good drainage is essential for California Christmas Bush to prevent waterlogging, which leads to root rot and fungal issues.

Feed California Christmas Bush every 6 months during the growing season with a balanced, slow-release fertilizer at the rate on the label. Established trees in good soil often need little extra feeding, so let weak growth or pale foliage guide you.

Stop feeding by late summer so new growth can harden before winter.

Choose a spot with full sun to partial shade and well-draining, acidic soil with high organic content. Avoid low spots where water collects after rain.

California Christmas Bush is suited to USDA Zone 12a.

Plant container-grown or balled-and-burlapped trees in spring or early autumn, setting the root flare at soil level, and water well after planting.

California Christmas Bush can spread to about 4 ft (1.2 m) and reach about 6 ft (2 m) tall. Space plants about 4 ft (1.2 m) apart so mature crowns don't crowd each other, and plant at least half that distance from buildings, fences and paths.

Prune California Christmas Bush while it is dormant in late winter: first remove dead, damaged and crossing branches, then thin lightly for shape.

If it flowers in spring, prune right after flowering instead so you don't remove next year's buds. Never take off more than about a quarter of the tree in one year.

California Christmas Bush is frost-tender (hardy to USDA zone 12). In colder areas grow it in a container and move it to a bright, frost-free place before the first frost.

California Christmas Bush can be propagated through softwood cuttings, seeds.
