Asparagus

Asparagus is a perennial vegetable that can keep producing up to 20 years and is grown differently from other vegetables. Early shoots emerging from the ground with the thickest stems are harvested during Spring. Later shoots is left to grow, eventually producing a mass of feathery foliage which is left to grow and replenish energy to the underground crown until it dies back in Winter. Grows best in areas which have cold winters.
