Hedypnois annua Plant Care

Hedypnois annua (Hyoseris mauritanica) belongs to the Asteraceae family within the Hyoseris genus. Hedypnois annua is native to the Mediterranean Region and neighboring areas from Canary Islands to Iran, and naturalized in Australia and in parts of the Americas. Hedypnois annua is also known as Hedypnois coronopifolia, Hedypnois crepidiformis, Hedypnois cretica.

Hedypnois annua displays a low rosette, spreading growth habit, reaching up to 0.5 ft tall with a spread of approximately 1 ft. Hedypnois annua produces small yellow daisy-like flowers in clusters.

Leaf size: approximately 3 inches.

Water a young or newly planted Hedypnois annua 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.

Hedypnois annua thrives in full sun to partial shade.

Hyoseris mauritanica tolerates temperatures of 50–75°F. Hedypnois annua prefers humidity levels of 40–60%.

Well-draining sandy soil mix with organic matter. Good drainage is essential for Hedypnois annua to prevent waterlogging, which leads to root rot and fungal issues.

Feed Hedypnois annua 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 soil mix with organic matter. Avoid low spots where water collects after rain.

Hedypnois annua 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.

Hedypnois annua can spread to about 1 ft (0.3 m) and reach about 1 ft (0 m) tall. Space plants about 1 ft (0.3 m) apart so mature crowns don't crowd each other, and plant at least half that distance from buildings, fences and paths.

Prune Hedypnois annua 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.

Hedypnois annua 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.

Hedypnois annua can be propagated through seeds.

Hedypnois annua is susceptible to aphids, whiteflies, spider mites. Inspect the foliage regularly, especially along leaf undersides and stems. Treat infestations promptly with insecticidal soap or neem oil to prevent spread.

Hedypnois annua grows outdoors in USDA Zone 12a. It survives winters down to planting zone 12a. Hedypnois annua is native to the Mediterranean Region and neighboring areas from Canary Islands to Iran, and naturalized in Australia and in parts of the Americas. In cooler regions, grow Hedypnois annua as a houseplant or bring it indoors before the first frost.
