What Is the Turnera?

Turnera (Turnera panamensis) belongs to the Passifloraceae family within the Turnera genus. Turnera is native to Central America and Northwestern Colombia.

Turnera displays a low spreading shrub growth habit, reaching up to 1.5 ft tall with a spread of approximately 2 ft. Turnera produces small, colorful, cup-shaped flowers.

Leaf size: approximately 3 inches.

How Often Should You Water a Turnera?

Water a young or newly planted Turnera 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.

What Soil Mix Works Best for a Turnera?

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

How Often Should You Fertilize a Turnera?

Feed Turnera 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.

Where Should You Plant a Turnera?

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.

Turnera 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.

How Far Apart Should You Plant a Turnera?

Turnera can spread to about 2 ft (0.6 m) and reach about 2 ft (0 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.

How Do You Prune a Turnera?

Prune Turnera 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.

How Do You Care for a Turnera in Winter?

Turnera 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.

How Do You Propagate a Turnera?

Turnera can be propagated through seeds, stem cuttings. Similar propagation techniques also apply to damiana plant care, which shares the same genus.

Is the Turnera Toxic to Pets and Children?

Pet safety not verified

The ASPCA does not list Turnera, so we can't confirm whether it is safe for cats and dogs. Keep pets from chewing it as a precaution.

This is a general caution, not veterinary or medical advice. If your pet ate a plant, contact your vet or animal poison control.

What Pests and Diseases Affect the Turnera?

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

What USDA Hardiness Zone Does the Turnera Need?

Turnera grows outdoors in USDA Zone 13a. It survives winters down to planting zone 13a. Turnera is native to Central America and Northwestern Colombia. In cooler regions, grow Turnera as a houseplant or bring it indoors before the first frost.
