Malus is a genus of about 30–55 species of small deciduous apple trees or shrubs in the family Rosaceae, including the domesticated orchard apple (M. pumila). The other species are generally known as crabapples, crab apples, crabs, or wild apples. The genus is native to the temperate zone of the Northern Hemisphere. Crabapples are popular as compact ornamental trees, providing blossom in Spring and colourful fruit in Autumn. The fruits often persist throughout Winter.
Numerous hybrid cultivars have been selected, of which 'Evereste' and 'Red Sentinel' have gained The Royal Horticultural Society's Award of Garden Merit. Crabapples are small and sour tasting, and visually resemble a small apple, particularly some apples known as the "Lady Apple", which is also known as Pomme d'Api, Lady's Finger, Wax Apple and Christmas Apple. The tree shown here is the hybrid Malus × scheideckeri 'Exzellenz Thiel'.
