Kale is a popular vegetable and a member of the cabbage family. It is a cruciferous vegetable. There are many different types of kale. The leaves can be green or purple, and have either a smooth or curly shape.
Kale (Brassica oleracea) is a leafy vegetable in the Brassica or cole crop family. It is usually grouped into the cooking greens category with collards, mustard, and Swiss chard, but it is actually more of a non-heading cabbage. The leaves grow from a central stem that elongates as it grows. Kale is a powerhouse of nutrients. The plants can be quite ornamental, with leaves that can be curly or tagged, purple or shades of green. It is considered a cool-season vegetable and can handle some frost, when mature. Kale is easy to grow from seeds (much easier than cabbage), either directly seeded into the soil or started indoors and then transplanted. It can be grown as a cut and come again vegetable, so a few plants may be all you need.
