Atlas Daisy Plant Care

Atlas Daisy (Rhodanthemum hosmariense) belongs to the Asteraceae family within the Rhodanthemum genus. Atlas Daisy is native to the Atlas Mountains of Morocco. Atlas Daisy is also known as Chrysanthemum hosmariense, Chrysanthemum maresii, Leucanthemum hosmariense.

Atlas Daisy displays a low rosette, spreading ground cover growth habit, reaching up to 0.5 ft tall with a spread of approximately 1.5 ft. Atlas Daisy produces daisy-like flowers in shades of pink, white, or purple.

Leaf size: approximately 2 inches.

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

Atlas Daisy thrives in full sun to partial shade.

Rhodanthemum hosmariense tolerates temperatures of 50–75°F. Atlas Daisy prefers humidity levels of 40–60%.

Well-draining sandy loam with added organic matter for moisture retention. Good drainage is essential for Atlas Daisy to prevent waterlogging, which leads to root rot and fungal issues.

Feed Atlas Daisy every 6 months during the growing season with a balanced, slow-release fertilizer at the rate on the label. Established shrubs 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 sandy loam with added organic matter for moisture retention. Avoid low spots where water collects after rain.

Atlas Daisy is suited to USDA Zone 12a.

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

Atlas Daisy can spread to about 2 ft (0.5 m) and reach about 1 ft (0 m) tall. Space plants about 2 ft (0.5 m) apart so mature crowns don't crowd each other, and plant at least half that distance from buildings, fences and paths.

Prune Atlas Daisy 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 shrub in one year.

Atlas Daisy 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.

Atlas Daisy can be propagated through seeds, division of clumps.

Atlas Daisy grows outdoors in USDA Zone 12a. It survives winters down to planting zone 12a. Atlas Daisy is native to the Atlas Mountains of Morocco. In cooler regions, grow Atlas Daisy as a houseplant or bring it indoors before the first frost.
