Carian Foxglove Plant Care

Carian Foxglove (Digitalis cariensis) belongs to the Plantaginaceae family within the Digitalis genus. Carian Foxglove is native to southwestern to southern Turkey.

Carian Foxglove displays an upright, spiky rosette growth habit, reaching up to 3 ft tall with a spread of approximately 1.5 ft. Carian Foxglove produces tall spikes of tubular flowers in shades of pink, purple, white, or yellow.

Leaf size: approximately 6 inches.

Water a young or newly planted Carian Foxglove 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.

Carian Foxglove thrives in partial shade to full sun.

Digitalis cariensis tolerates temperatures of 50–75°F. Carian Foxglove prefers humidity levels of 40–70%.

Well-draining, fertile soil with added compost or peat moss. Good drainage is essential for Carian Foxglove to prevent waterlogging, which leads to root rot and fungal issues.

Feed Carian Foxglove 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 partial shade to full sun and well-draining, fertile soil with added compost or peat moss. Avoid low spots where water collects after rain.

Carian Foxglove is suited to USDA Zone 7a – 9b.

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.

Carian Foxglove can spread to about 2 ft (0.5 m) and reach about 3 ft (1 m) tall. Space plants about 2 ft (0.5 m) apart so mature crowns don't crowd each other, and plant at least half that distance from buildings, fences and paths.

Prune Carian Foxglove 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.

Carian Foxglove is hardy down to USDA zone 7a, 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.

Carian Foxglove can be propagated through seeds. Similar propagation techniques also apply to rusty foxglove plant care, which shares the same genus.

Carian Foxglove is susceptible to aphids, slugs, snails. Inspect the foliage regularly, especially along leaf undersides and stems. Treat infestations promptly with insecticidal soap or neem oil to prevent spread.

Carian Foxglove grows outdoors in USDA Zone 7a – 9b. It survives winters down to planting zone 7a. Carian Foxglove is native to southwestern to southern Turkey.
