Fragrant Staircase Flower Plant Care

Fragrant Staircase Flower (Gustavia romeroi) belongs to the Lecythidaceae family within the Gustavia genus. Fragrant Staircase Flower is native to the Magdalena River Basin of Colombia.

Fragrant Staircase Flower displays a tall tree, canopy-forming growth habit, reaching up to 30 ft tall with a spread of approximately 15 ft. Fragrant Staircase Flower produces large, showy flowers in shades of white, pink, or purple.

Leaf size: approximately 12 inches.

Water a young or newly planted Fragrant Staircase Flower every 7–14 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.

Fragrant Staircase Flower thrives in filtered sunlight, partial shade. Avoid placing Fragrant Staircase Flower in direct, harsh sunlight for extended periods, as this can scorch the foliage.

Gustavia romeroi tolerates temperatures of 65–85°F. Fragrant Staircase Flower prefers humidity levels of 60–80%. A pebble tray or humidifier helps maintain adequate moisture around the plant.

Rich, well-draining soil with high organic content. Good drainage is essential for Fragrant Staircase Flower to prevent waterlogging, which leads to root rot and fungal issues.

Feed Fragrant Staircase Flower 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.

Choose a spot with filtered sunlight, partial shade and rich, well-draining soil with high organic content. Avoid low spots where water collects after rain.

Fragrant Staircase Flower is suited to USDA Zone 13b.

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.

Fragrant Staircase Flower can spread to about 15 ft (4.6 m) and reach about 30 ft (9 m) tall. Space plants about 15 ft (4.6 m) apart so mature crowns don't crowd each other, and plant at least half that distance from buildings, fences and paths.

Prune Fragrant Staircase Flower 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.

Fragrant Staircase Flower 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.

Fragrant Staircase Flower can be propagated through seeds, air layering. Similar propagation techniques also apply to heavenly bamboo plant care, which shares the same genus.
