Setcreasea pallida Purple Heart, Purple Queen1

Edward F. Gilman2

Introduction

This sprawling, evergreen ground cover produces deep purple foliage and stems when grown in full sun (Fig.1). The rather brittle stems, a foot or more high, have a tendency to flop over, creating a trailing effect that lends itself nicely to informal planting beds, rock gardens, or containers. It also cascades nicely over retaining walls and does well in a hanging basket. The rather inconspicuous, three-petalled, pale pink, one-inch flowers are produced from the tips of stems and last only one morning.

Use and Management

Growing in full sun to partial shade, purple heart thrives in a wide variety of soils. In north Florida, frost may kill back the tops, but in warm weather in the spring the plants recover quickly. Set plants on 12-inch centers for quick cover. Plants should be well-watered until established and then will only require attention during periods of extended drought.
Propagation is by stem cuttings, which root easily.

Pests and Diseases

No pests or diseases of major concern. Mites and chewing insects may occasionally cause injury.
