Splendid foxglove Plant Care

Splendid foxglove (Ourisia sessilifolia subsp. splendida) belongs to the Plantaginaceae family within the Ourisia genus. Splendid foxglove is native to high-elevation habitats in the South Island and Stewart Island of New Zealand. Splendid foxglove is also known as Magenta rock star.

Splendid foxglove displays a low rosette, spreading ground cover growth habit, reaching up to 0.5 ft tall with a spread of approximately 1 ft. Splendid foxglove produces small, tubular flowers in shades of pink, purple, or white.

Leaf size: approximately 2 inches.

Water a young or newly planted Splendid foxglove every 4–7 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.

Splendid foxglove thrives in partial shade to full shade. The optimal light range is 100–1,000 lux. Avoid placing Splendid foxglove in direct, harsh sunlight for extended periods, as this can scorch the foliage.

Ourisia sessilifolia subsp. splendida tolerates temperatures of 50–75°F. Splendid foxglove prefers humidity levels of 40–70%.

Well-draining, slightly acidic soil with good organic content. Good drainage is essential for Splendid foxglove to prevent waterlogging, which leads to root rot and fungal issues.

Feed Splendid 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 shade and well-draining, slightly acidic soil with good organic content. Avoid low spots where water collects after rain.

Splendid foxglove is suited to USDA Zone 7a – 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.

Splendid foxglove can spread to about 1 ft (0.3 m) and reach about 1 ft (0 m) tall. Space plants about 1 ft (0.3 m) apart so mature crowns don't crowd each other, and plant at least half that distance from buildings, fences and paths.

Prune Splendid 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.

Splendid 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.

Splendid foxglove can be propagated through seeds, division of clumps. Similar propagation techniques also apply to tufted foxglove plant care, which shares the same genus.

Splendid 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.
