Description

Flower Sprouts (Brassica oleracea), also widely known by the trade name Kalettes, is a modern open-pollinated hybrid innovation created by crossing classic Brussels sprouts with curly kale. Instead of producing tight, solid buttons, this plant forms stunning, open rosette-like mini heads along sturdy 24- to 36-inch stalks. The frilly rosettes feature vibrant green leaves with rich purple-magenta veining. Combining the sweet, nutty flavor of Brussels sprouts with the fresh texture of kale, Flower Sprouts offer a unique culinary treat—perfect for roasting, sauteing, stir-frying, or enjoying fresh in cold autumn salads.
