Justicia carnea Jacobinia, Flamingo Plant, Brazilian-plume

Edward F. Gilman

Introduction

Jacobinia is an upright, evergreen shrub, 3 to 7 feet tall and wide, with large, 6 inch long, dark green leaves and upwardly facing plumes of tubular, slightly fragrant flower clusters in rose-purple, red, yellow, orange, apricot, or white (depending on the selection), which appear from early summer until fall. The plant cycles through 2 to 4 major flowering periods during the year, with few flowers in between. Many stems appear from the center of the plant and rise straight up for several feet before branching. The rapid growth and evergreen nature make jacobinia ideal for use as a foundation or mass planting. It may be used in various containers, or it may even be trained into an attractive espalier. Use it in front of a green shrubbery border to create a color accent throughout the warm months.

Use and Management

Rain and irrigation weigh the foliage down and cause the branches to spread out, sometimes touching the ground. This limits height growth and opens up the plant to allow light to enter the interior, stimulating growth from the lower stem and inner branches. It has a place in almost every garden in USDA hardiness zones 8b through 11.

Jacobinia should be grown on rich, well-drained soil that receives ample moisture in a location shaded from full-day sun. Although tender to frost, plants will grow back quickly in springtime in USDA hardiness zones 8 and 9. The only necessary pruning during the growing season should be limited to removal of dead flower heads or occasional pinching to stimulate branching. Since flowers form on new growth, prune early in the spring so flower display is not reduced. This increases the number of branches and flowers and creates an attractive, full plant. Older plants benefit from rejuvenation type pruning where most of the taller stems are cut back to a node close to the ground. If this is performed each year, plants should last for many years.

Propagation is by cuttings.

Pest and Diseases

Nematodes and spider mites. Caterpillars occasionally chew portions of the foliage, but these will not kill the plant.

No pests or diseases are of major concern.
