Caucasian Mountain Avens Plant Care

Caucasian Mountain Avens (Dryas caucasica) belongs to the Rosaceae family within the Dryas genus.

Caucasian Mountain Avens displays a low spreading shrub growth habit, reaching up to 1.5 ft tall with a spread of approximately 2 ft. Caucasian Mountain Avens produces showy white or yellow flowers with five petals.

Leaf size: approximately 2.5 inches.

Water a young or newly planted Caucasian Mountain Avens 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.

Caucasian Mountain Avens thrives in full sun to partial shade.

Dryas caucasica tolerates temperatures of 50–75°F. Caucasian Mountain Avens prefers humidity levels of 40–60%.

Well-draining, acidic soil with high organic content. Good drainage is essential for Caucasian Mountain Avens to prevent waterlogging, which leads to root rot and fungal issues.

Feed Caucasian Mountain Avens 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 to partial shade and well-draining, acidic soil with high organic content. Avoid low spots where water collects after rain.

Caucasian Mountain Avens 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.

Caucasian Mountain Avens can spread to about 2 ft (0.6 m) and reach about 2 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 Caucasian Mountain Avens 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.

Caucasian Mountain Avens 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.

Caucasian Mountain Avens can be propagated through seeds, division of clumps. Similar propagation techniques also apply to mountain avens plant care, which shares the same genus.
