Also known as poor man's cardomom, this plant has highly aromatic leaves that smell just like the cardomom spice, and can be used instead. Like ginger, it will form large clumps up to 2 metres high, and is an excellent addition if you wish to create that tropical ambience in your garden. It gives off a wonderful spicy aroma if you brush the leaves. An easy care plant for a pot or in the conservatory.
