Cardoon

Cardoon

A very fun and dramatic perennial from the Mediterranean, Cardoons are fun and easy to grow. They work equally as well in the perennial border as they do in the veggie garden and their big, bold silvery foliage and gorgeous purple flowers create quite the show. The edible part of the cardoon is the very large leaf stalk that can be cut up and boiled to make it tender. When cooked the right way cardoons are incredibly delicious and add a unique texture to a dish. Hardy to about 15F. but in climates that get cooler than that you can easily grow it as an annual.
