Narrowleaf Groundcherry Plant Care

Narrowleaf Groundcherry (Physalis angustifolia) belongs to the Solanaceae family within the Physalis genus. Narrowleaf Groundcherry is native to the Gulf Coast shoreline of the Southeastern United States. Narrowleaf Groundcherry is also known as Coastal Groundcherry.

Narrowleaf Groundcherry displays an upright, spreading shrub growth habit, reaching up to 2 ft tall with a spread of approximately 3 ft. Narrowleaf Groundcherry produces small, lantern-like orange or yellow blooms.

Leaf size: approximately 4 inches.

Water a young or newly planted Narrowleaf Groundcherry 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.

Narrowleaf Groundcherry thrives in full sun to partial shade.

Physalis angustifolia tolerates temperatures of 60–80°F. Narrowleaf Groundcherry prefers humidity levels of 40–60%.

Well-draining, fertile soil with a slightly acidic pH. Good drainage is essential for Narrowleaf Groundcherry to prevent waterlogging, which leads to root rot and fungal issues.

Feed Narrowleaf Groundcherry 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, fertile soil with a slightly acidic pH. Avoid low spots where water collects after rain.

Narrowleaf Groundcherry 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.

Narrowleaf Groundcherry can spread to about 3 ft (0.9 m) and reach about 2 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 Narrowleaf Groundcherry 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.

Narrowleaf Groundcherry 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.

Narrowleaf Groundcherry can be propagated through seeds, division of rhizomes. Similar propagation techniques also apply to chinese lantern plant plant care, which shares the same genus.

Narrowleaf Groundcherry 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.

Narrowleaf Groundcherry grows outdoors in USDA Zone 13a. It survives winters down to planting zone 13a. Narrowleaf Groundcherry is native to the Gulf Coast shoreline of the Southeastern United States. In cooler regions, grow Narrowleaf Groundcherry as a houseplant or bring it indoors before the first frost.
