Eriolarynx australis Plant Care

Eriolarynx australis (Eriolarynx australis) belongs to the Solanaceae family within the Eriolarynx genus. Eriolarynx australis is native to Bolivia and northwest Argentina.

Eriolarynx australis displays a compact, mounding shrub growth habit, reaching up to 2.5 ft tall with a spread of approximately 3 ft. Eriolarynx australis produces small, trumpet-shaped flowers in shades of purple and white.

Leaf size: approximately 4 inches.

Water a young or newly planted Eriolarynx australis 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.

Eriolarynx australis thrives in full sun to partial shade.

Eriolarynx australis tolerates temperatures of 60–80°F. Eriolarynx australis prefers humidity levels of 40–60%.

Well-draining, loamy soil with added compost for nutrients. Good drainage is essential for Eriolarynx australis to prevent waterlogging, which leads to root rot and fungal issues.

Feed Eriolarynx australis 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, loamy soil with added compost for nutrients. Avoid low spots where water collects after rain.

Eriolarynx australis 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.

Eriolarynx australis can spread to about 3 ft (0.9 m) and reach about 3 ft (1 m) tall. Space plants about 3 ft (0.9 m) apart so mature crowns don't crowd each other, and plant at least half that distance from buildings, fences and paths.

Prune Eriolarynx australis 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.

Eriolarynx australis 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.

Eriolarynx australis can be propagated through stem cuttings, division, air layering.

Eriolarynx australis is susceptible to aphids, whiteflies, spider mites. Inspect the foliage regularly, especially along leaf undersides and stems. Treat infestations promptly with insecticidal soap or neem oil to prevent spread.

Eriolarynx australis grows outdoors in USDA Zone 13a. It survives winters down to planting zone 13a. Eriolarynx australis is native to Bolivia and northwest Argentina. In cooler regions, grow Eriolarynx australis as a houseplant or bring it indoors before the first frost.
