Kale, or leaf cabbage, refers to several varieties within the species Brassica oleracea. Many are beautiful ornamental kales that can serve dual purpose in an edible landscape, offering a variety of foliage colors and textures.
Want to grow kale indoors? Keep in a cool location and use lower-heat grow lights such as LEDs, HOT5 Fluorescents or CFLs, versus HID lamps. You can grow kale and related leafy crops under shorter light periods of 11-13 hours to discourage bolting, or grow them under longer photoperiods of 14 to 16 hours to boost production- but you'll need to harvest more quickly.
