Hardy in USDA Zones 9-11, shrimp plants can reach heights of up to five feet in ideal conditions. The flowers, which attract hummingbirds and butterflies, bloom throughout the year in tropical climates.

Cultivation and History

While not as economically significant as other plants, the shrimp plant has made its mark in the ornamental gardening scene. Named after Scottish gardener James Justice and botanist Townsend S. Brandegee, Justicia brandegeana has a rich history in horticulture.

Propagation methods for shrimp plants include stem cuttings, division, and transplanting, making it easy to acquire and grow these stunning shrubs in your garden.

From Stem Cuttings

Select healthy shoots in spring or summer for four- to six-inch cuttings.
Dip cut ends in rooting hormone and plant in a 50:50 mix of peat moss and perlite.
Keep the cuttings in indirect light and moist until roots develop.

Via Division

Divide large in-ground clumps or cramped container specimens in spring.
Separate roots and shoots of divided sections for transplanting.

Via Transplanting

Plant in well-draining, fertile soils with a pH of 6.0-7.0.
Space the plants one to five feet apart in full sun to partial shade.

How to Grow Shrimp Plants

Once you’ve planted your shrimp plants, it’s essential to provide them with the right care to ensure their health and vitality.

Climate and Exposure Needs

Ideal for USDA Zones 9-11, bring indoors in colder climates.
