Ulex densus Plant Care

Ulex densus (Ulex densus) belongs to the Fabaceae family within the Ulex genus. Ulex densus is native to Portugal.

Ulex densus displays a spiny, upright shrub growth habit, reaching up to 4 ft tall with a spread of approximately 3 ft. Ulex densus produces bright yellow pea-like flowers.

Leaf size: approximately 1.5 inches.

Water a young or newly planted Ulex densus 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.

Ulex densus thrives in full sun.

Ulex densus tolerates temperatures of 50–80°F. Ulex densus prefers humidity levels of 40–60%.

Well-draining sandy soil with added organic matter for nutrients. Good drainage is essential for Ulex densus to prevent waterlogging, which leads to root rot and fungal issues.

Feed Ulex densus 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 and well-draining sandy soil with added organic matter for nutrients. Avoid low spots where water collects after rain.

Ulex densus 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.

Ulex densus can spread to about 3 ft (0.9 m) and reach about 4 ft (1 m) tall. Space plants about 3 ft (0.9 m) apart so mature crowns don't crowd each other, and plant at least half that distance from buildings, fences and paths.

Prune Ulex densus 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.

Ulex densus 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.

Ulex densus can be propagated through seeds. Similar propagation techniques also apply to gorse plant care, which shares the same genus.

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

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