Chaenomeles is a genus of three species of deciduous spiny shrubs, usually 1 – 3 m tall, in the family Rosaceae. They are native to Southeast Asia. Although all quince species have flowers, gardeners often refer to these species as "flowering quince", since Chaenomeles are grown ornamentally for their flowers, not for their fruits. These plants have also been called "Japanese quince"; however all do produce apple-like, rather bitter fruit.

Used a lot in bonsai growing, sometimes as individual specimens but more often as clumps, often used as companion plants. They grow fairly readily from seed but are usually acquired by splitting original clumps, ensuring that there is at least a reasonable amount of root on the piece you are breaking off. This method can be used on the shoots that appear on the main root system.

They grow freely but branches appear unpredictably not to a standard shape; they are best developed as informal plants or small clumps. Prune back after flowering to the nearest bud; if there are no buds do not cut back or you will lose the branch.

Not susceptible to many pests or diseases but bacterial Fireblight can sometimes be a problem; the flowers and shoots wither and dieback - if untreated it can kill the plant but usually it responds to cutting back the affected part, removing and burning.
