Grow your own edible Ginger! This is a well known Asian cooking ingredient which can also be grown in the UK as a summer garden plant, for its tropical foliage and delicate, fragrant flowers. You can dig up the rhizome and "harvest" the ginger at any time for your cooking needs, or leave the plant to multiply and get bigger each year. Like all gingers, it is frost tender, so best that the rhizome is dug up and kept dry over winter or placed in a pot and kept inside growing or in a greenhouse. You can in the spring then divide the rhizome carefully to produce further plants.
