Desert Alyssum Plant Care

Desert Alyssum (Alyssum desertorum) belongs to the Brassicaceae family within the Alyssum genus. Desert Alyssum is native to Europe, North Africa and Asia, and.

Desert Alyssum displays a low spreading ground cover growth habit, reaching up to 0.5 ft tall with a spread of approximately 1.5 ft. Desert Alyssum produces small clusters of tiny, fragrant white, pink, or purple flowers.

Leaf size: approximately 1 inches.

Water a young or newly planted Desert Alyssum every 3–7 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.

Desert Alyssum thrives in full sun to partial shade.

Alyssum desertorum tolerates temperatures of 50–75°F. Desert Alyssum prefers humidity levels of 40–70%.

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

Feed Desert Alyssum every 4 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. Avoid low spots where water collects after rain.

Desert Alyssum is suited to USDA Zone 4a – 9b.

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.

Desert Alyssum 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 Desert Alyssum 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.

Desert Alyssum is hardy down to USDA zone 4a, so once established it can stay outdoors through winter in that zone and warmer ones.

Water deeply in late autumn before the ground freezes, and spread a 5–8 cm (2–3 in) layer of mulch over the root zone, keeping it away from the trunk.

Young and container-grown shrubs need extra protection: roots in a pot freeze much more easily than roots in the ground.

Desert Alyssum can be propagated through seeds. Similar propagation techniques also apply to alyssum pulvinare plant care, which shares the same genus.

Desert Alyssum is susceptible to aphids, cabbage worms, flea beetles. Inspect the foliage regularly, especially along leaf undersides and stems. Treat infestations promptly with insecticidal soap or neem oil to prevent spread.
