Brassica oleracea

Common Name:
Wild Cabbage (includes cultivated varieties such as Broccoli, Cauliflower, Kale, Brussels Sprouts, and Cabbage)

Description:
Brassica oleracea is a highly versatile and widely cultivated plant species, from which many popular vegetable varieties originate, including cabbage, broccoli, cauliflower, kale, Brussels sprouts, and collard greens. This biennial or perennial plant is known for its thick, waxy leaves and ability to withstand cool temperatures. Different cultivated forms exhibit various growth habits, including tight leafy heads (cabbage), edible flower clusters (broccoli and cauliflower), and small leafy rosettes (Brussels sprouts).

It thrives in well-drained, fertile soil with consistent moisture and benefits from full sun exposure. Regular feeding with organic matter or balanced fertilisers will support healthy growth and maximise yields. Some varieties are more tolerant of frost, while others prefer milder conditions. Brassica oleracea is an essential plant for vegetable gardens, providing nutritious, vitamin-rich produce throughout the growing season.
