Mimosa pigra: complete guide

Overview

Mimosa pigra, also known as bashful plant, sensitive plant, or black mimosa, is a fascinating tropical shrub from America. This plant is renowned for its unique characteristic: the leaves close upon touch or disturbance. The plant bears bright pink pom-pom flowers throughout the warm season.

Appearance and bloom

The plant grows to 1-2 meters tall and forms a spreading, branchy shrub. The leaves are doubly pinnate and extremely sensitive to touch and temperature changes. Upon touching they fold immediately. Bright pink pom-pom-like flowers appear during warm months. Subsequently hairy pod-shaped fruits develop.

Ideal location

Mimosa pigra thrives best in full sun with at least 6-8 hours of direct sunlight. Warmth is essential - in temperate climates it is usually grown in pots on sunny windowsills. Protected locations prevent leaf damage from wind.

Soil

Well-draining, slightly acidic to neutral soil is favorable. Add sand to heavy clay soils. The plant tolerates diverse soil types.

Watering

Regular, even moisture is required, especially during active growth. Do not let the soil dry out completely. In winter water less.

Pruning

Pruning is not essential, but it can help maintain a more compact form. After blooming you may remove spent flowers.

Maintenance calendar

Spring: Plant resumes growth, regular water and warm climate needed. Summer: Full growth, flowering appears, water weekly. Fall: Growth slows, less water. Winter: Minimal maintenance, cool preferences encourage dormancy.

Winter hardiness

Mimosa pigra is not winter-hardy and can only overwinter outdoors in USDA zones 9-12. In cold areas it is grown as an annual or kept indoors.

Companion plants

Perfect as an exotic houseplant or in tropical gardens with other heat-loving species.
