Impressed Santolina Plant Care

Impressed Santolina (Santolina impressa) belongs to the Asteraceae family within the Santolina genus. Impressed Santolina is native to southwest Portugal specifically the area between Setúbal and Sines.

Impressed Santolina displays a low mounding shrub growth habit, reaching up to 1 ft tall with a spread of approximately 2 ft. Impressed Santolina produces small yellow button-like flowers.

Leaf size: approximately 1 inches.

Water a young or newly planted Impressed Santolina every 7–14 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.

Impressed Santolina thrives in full sun.

Santolina impressa tolerates temperatures of 50–80°F. Impressed Santolina prefers humidity levels of 30–60%.

Well-draining sandy soil with low fertility. Good drainage is essential for Impressed Santolina to prevent waterlogging, which leads to root rot and fungal issues.

Feed Impressed Santolina 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.

The PlantoScan app can remind you when to water and when to fertilize each plant.

Choose a spot with full sun and well-draining sandy soil with low fertility. Avoid low spots where water collects after rain.

Impressed Santolina 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.

Impressed Santolina can spread to about 2 ft (0.6 m) and reach about 1 ft (0 m) tall. Space plants about 2 ft (0.6 m) apart so mature crowns don't crowd each other, and plant at least half that distance from buildings, fences and paths.

Prune Impressed Santolina 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.

Impressed Santolina 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.

Impressed Santolina can be propagated through cuttings, division. Similar propagation techniques also apply to cotton lavender plant care, which shares the same genus.

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

Impressed Santolina grows outdoors in USDA Zone 12a. It survives winters down to planting zone 12a. Impressed Santolina is native to southwest Portugal specifically the area between Setúbal and Sines. In cooler regions, grow Impressed Santolina as a houseplant or bring it indoors before the first frost.
