Hovea impressinerva Plant Care

Hovea impressinerva (Hovea impressinerva) belongs to the Fabaceae family within the Hovea genus. Hovea impressinerva is native to south-eastern continental Australia.

Hovea impressinerva displays an upright shrub growth habit, reaching up to 3 ft tall with a spread of approximately 2 ft. Hovea impressinerva produces showy pea-like flowers in shades of blue, purple, or pink.

Leaf size: approximately 4 inches.

Water a young or newly planted Hovea impressinerva 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.

Hovea impressinerva thrives in full sun to partial shade.

Hovea impressinerva tolerates temperatures of 50–80°F. Hovea impressinerva prefers humidity levels of 40–70%.

Well-draining sandy loam with added organic matter. Good drainage is essential for Hovea impressinerva to prevent waterlogging, which leads to root rot and fungal issues.

Feed Hovea impressinerva 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 sandy loam with added organic matter. Avoid low spots where water collects after rain.

Hovea impressinerva 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.

Hovea impressinerva can spread to about 2 ft (0.6 m) and reach about 3 ft (1 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 Hovea impressinerva 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.

Hovea impressinerva 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.

Hovea impressinerva can be propagated through seeds, cuttings. Similar propagation techniques also apply to purple hovea plant care, which shares the same genus.

Hovea impressinerva grows outdoors in USDA Zone 12a. It survives winters down to planting zone 12a. Hovea impressinerva is native to south-eastern continental Australia. In cooler regions, grow Hovea impressinerva as a houseplant or bring it indoors before the first frost.
