Lacistema robustum Plant Care

Lacistema robustum (Lacistema robustum) belongs to the Lacistemataceae family within the Lacistema genus. Lacistema robustum is native to Brazil.

Lacistema robustum displays a compact, bushy shrub growth habit, reaching up to 3 ft tall with a spread of approximately 2 ft. Lacistema robustum produces small, fragrant white flowers in clusters.

Leaf size: approximately 4 inches.

Water a young or newly planted Lacistema robustum 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.

Lacistema robustum thrives in partial shade to full sun.

Lacistema robustum tolerates temperatures of 60–80°F. Lacistema robustum prefers humidity levels of 50–70%. A pebble tray or humidifier helps maintain adequate moisture around the plant.

Well-draining, acidic soil mix with high organic content. Good drainage is essential for Lacistema robustum to prevent waterlogging, which leads to root rot and fungal issues.

Feed Lacistema robustum 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.

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

Choose a spot with partial shade to full sun and well-draining, acidic soil mix with high organic content. Avoid low spots where water collects after rain.

Lacistema robustum 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.

Lacistema robustum 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 Lacistema robustum 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.

Lacistema robustum 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.

Lacistema robustum can be propagated through seeds, stem cuttings. Similar propagation techniques also apply to lacistema lucidum plant care, which shares the same genus.

Lacistema robustum is susceptible to scale insects, spider mites, mealybugs. Inspect the foliage regularly, especially along leaf undersides and stems. Treat infestations promptly with insecticidal soap or neem oil to prevent spread.

Lacistema robustum grows outdoors in USDA Zone 13a. It survives winters down to planting zone 13a. Lacistema robustum is native to Brazil. In cooler regions, grow Lacistema robustum as a houseplant or bring it indoors before the first frost.
