Northern rock jasmine Plant Care

Northern rock jasmine (Androsace septentrionalis) belongs to the Primulaceae family within the Androsace genus. Northern rock jasmine is also known as Fairy cups, Bird's eye.

Northern 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. Northern 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 Northern 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.

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

Androsace septentrionalis tolerates temperatures of 50–75°F. Northern 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 Northern rock jasmine to prevent waterlogging, which leads to root rot and fungal issues.

Feed Northern 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.

Northern rock jasmine 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.

Northern 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 Northern 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.

Northern rock jasmine 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.

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

Northern 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.

Northern rock jasmine grows outdoors in USDA Zone 12a. It survives winters down to planting zone 12a. In cooler regions, grow Northern rock jasmine as a houseplant or bring it indoors before the first frost.
