Siberian rock jasmine Plant Care

Siberian rock jasmine (Androsace sarmentosa) belongs to the Primulaceae family within the Androsace genus. Siberian rock jasmine is native to the Himalayas and Tibet. Siberian rock jasmine is also known as Flowering wintergreen.

Siberian rock jasmine displays a low rosette, clumping habit growth habit, reaching up to 0.5 ft tall with a spread of approximately 0.5 ft. Siberian rock jasmine produces small, delicate flowers in shades of pink, white, or purple.

Leaf size: approximately 1.5 inches.

Water a young or newly planted Siberian rock jasmine 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.

Siberian rock jasmine thrives in bright indirect light. Avoid placing Siberian rock jasmine in direct, harsh sunlight for extended periods, as this can scorch the foliage.

Androsace sarmentosa tolerates temperatures of 50–75°F. Siberian rock jasmine prefers humidity levels of 40–60%.

Well-draining soil mix with high organic content, such as a mix of peat moss, perlite, and coarse sand. Good drainage is essential for Siberian rock jasmine to prevent waterlogging, which leads to root rot and fungal issues.

Feed Siberian rock jasmine 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 bright indirect light and well-draining soil mix with high organic content, such as a mix of peat moss, perlite, and coarse sand. Avoid low spots where water collects after rain.

Siberian rock jasmine is suited to USDA Zone 3a – 8b.

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.

Siberian rock jasmine can spread to about 1 ft (0.2 m) and reach about 1 ft (0 m) tall. Space plants about 1 ft (0.2 m) apart so mature crowns don't crowd each other, and plant at least half that distance from buildings, fences and paths.

Prune Siberian rock jasmine 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.

Siberian rock jasmine is hardy down to USDA zone 3a, 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.

Siberian rock jasmine can be propagated through seeds, division of clumps, or root cuttings. Similar propagation techniques also apply to alban androsace plant care, which shares the same genus.

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