Parietaria coriacea subsp. attenuifolia Plant Care

Parietaria coriacea subsp. attenuifolia (Haumaniastrum coriaceum subsp. attenuifolium) belongs to the Lamiaceae family within the Haumaniastrum genus. Parietaria coriacea subsp. attenuifolia is native to Spain, Italy, Greece.

Parietaria coriacea subsp. attenuifolia displays a low spreading ground cover growth habit, reaching up to 0.5 ft tall with a spread of approximately 1.5 ft. Parietaria coriacea subsp. attenuifolia produces small tubular purple flowers in clusters.

Leaf size: approximately 2 inches.

Water a young or newly planted Parietaria coriacea subsp. attenuifolia 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.

Parietaria coriacea subsp. attenuifolia thrives in partial to full shade. The optimal light range is 100–500 lux. Avoid placing Parietaria coriacea subsp. attenuifolia in direct, harsh sunlight for extended periods, as this can scorch the foliage.

Haumaniastrum coriaceum subsp. attenuifolium tolerates temperatures of 60–75°F. Parietaria coriacea subsp. attenuifolia prefers humidity levels of 40–60%.

Well-draining loamy soil with added organic matter for moisture retention. Good drainage is essential for Parietaria coriacea subsp. attenuifolia to prevent waterlogging, which leads to root rot and fungal issues.

Feed Parietaria coriacea subsp. attenuifolia 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 to full shade and well-draining loamy soil with added organic matter for moisture retention. Avoid low spots where water collects after rain.

Parietaria coriacea subsp. attenuifolia is suited to USDA Zone 13a.

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.

Parietaria coriacea subsp. attenuifolia can spread to about 2 ft (0.5 m) and reach about 1 ft (0 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 Parietaria coriacea subsp. attenuifolia 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.

Parietaria coriacea subsp. attenuifolia is frost-tender (hardy to USDA zone 13). In colder areas grow it in a container and move it to a bright, frost-free place before the first frost.

Parietaria coriacea subsp. attenuifolia can be propagated through stem cuttings, division. Similar propagation techniques also apply to green ripple peperomia plant care, which shares the same genus.

Parietaria coriacea subsp. attenuifolia grows outdoors in USDA Zone 13a. It survives winters down to planting zone 13a. Parietaria coriacea subsp. attenuifolia is native to Spain, Italy, Greece. In cooler regions, grow Parietaria coriacea subsp. attenuifolia as a houseplant or bring it indoors before the first frost.
