Brassica oleracea 'White Peacock' White Peacock Flowering Kale1

Edward F. Gilman 2

Introduction

The 'White Peacock' ornamental cabbage has an open head with finely-divided foliage (Fig. 1). It does not make the tight head common on cabbages sold in the grocery store (Capitata group). Leaves on ornamental cabbage are edible but more showy than the Capitata group, and they are displayed in loose, showy rosettes. Fringed leaves are bluish-green with prominent, white veins.

Use and Management

Cabbage can be used reliably as a bedding plant in the fall and spring throughout the deep south. Some die back may occur in the coolest regions of the south and into north Florida in a very cold winter. It can be used throughout the winter in central and south Florida. When flowers begin to appear, it is time to remove the plants and replant with a more heat tolerant bedding plant. Propagation is by seed.

Pests and Diseases

Caterpillars can eat holes in the leaves. Although this does not kill the plant, it makes them unattractive.
