Also known as Canna, this familiar ornamental plant is a common sight in UK bedding schemes but did you know its starchy roots have been cultivated for thousands of years as a major crop? Much like potatoes, these tasty rhizomes can be boiled, roasted or baked, used in soups, mashed, or even in gnocchi! Have you ever watched a flamboyant TV chef lovingly wrap a fish parcel with an exotic banana leaf? Well, canna leaves are a perfect citrus scented substitute.
