Quince—Chaenomeles spp.
Family Rosaceae (Rose family)

Plant Identification

Quince is an easy-to-grow deciduous shrub.  Some species grow wide while others are compact and grow low to the ground.  Young leaves are reddish, becoming shiny green when mature.  Single or double flowers are produced in colors such as pink, apricot, red, orange, coral, salmon, white or purple.  Blossoms attract birds.  Many plants are thorny.  Small fruit forms after bloom.

Optimum conditions for growth

Quince is pretty indestructible and often grown as hedges and barriers.  It does best in areas with full sun and can tolerate both extremely hot and cold temperatures.  It can grow well in light and heavy soil and requires moderate to heavy amounts of water.  Prune at bloom time to shape or limit growth.
