Asparagus is one of the best options for cold-climate gardeners interested in growing perennial vegetables. Most people – and mainstream plant retailers – have never heard of the perennial vegetables that grow in cold climates. You might be hard pressed to find American groundnut tubers or Good King Henry seeds but it’s easy to find asparagus cultivars and accompanying recipes and friends to use them up. Plus, asparagus prefers cooler climates and will continue to produce an abundance of delicious spears for up to 30 years.
