Iochroma lehmannii Plant Care

Iochroma lehmannii (Iochroma lehmannii) belongs to the Solanaceae family within the Iochroma genus. Iochroma lehmannii is native to Ecuador, specifically in the Chimborazo Province in the High Andes.

Iochroma lehmannii displays an upright, branching shrub growth habit, reaching up to 5 ft tall with a spread of approximately 3 ft. Iochroma lehmannii produces tubular flowers in shades of purple, blue, or red.

Leaf size: approximately 6 inches.

Water a young or newly planted Iochroma lehmannii every 7–10 days, soaking the whole root zone, until it is established — usually one to two growing seasons. Established trees mainly need water during long dry spells. In a container, water whenever the top few centimetres of soil are dry.

Iochroma lehmannii thrives in full sun to partial shade.

Iochroma lehmannii tolerates temperatures of 50–80°F. Iochroma lehmannii prefers humidity levels of 40–70%.

Well-draining, fertile soil with added organic matter. Good drainage is essential for Iochroma lehmannii to prevent waterlogging, which leads to root rot and fungal issues.

Feed Iochroma lehmannii every 6 months during the growing season with a balanced, slow-release fertilizer at the rate on the label. Established trees 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.

The PlantoScan app can remind you when to water and when to fertilize each plant.

Choose a spot with full sun to partial shade and well-draining, fertile soil with added organic matter. Avoid low spots where water collects after rain.

Iochroma lehmannii is suited to USDA Zone 12a.

Plant container-grown or balled-and-burlapped trees in spring or early autumn, setting the root flare at soil level, and water well after planting.

Iochroma lehmannii can spread to about 3 ft (0.9 m) and reach about 5 ft (2 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 Iochroma lehmannii 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 tree in one year.

Iochroma lehmannii 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.

Iochroma lehmannii can be propagated through softwood cuttings, seeds. Similar propagation techniques also apply to tree iochroma plant care, which shares the same genus.

Iochroma lehmannii 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.

Iochroma lehmannii grows outdoors in USDA Zone 12a. It survives winters down to planting zone 12a. Iochroma lehmannii is native to Ecuador, specifically in the Chimborazo Province in the High Andes. In cooler regions, grow Iochroma lehmannii as a houseplant or bring it indoors before the first frost.
