Malus × robusta, called Siberian crab apple along with other members of its genus, is a hybrid species of flowering plant in the family Rosaceae.[1] It is the result of a cross between Malus baccata (Siberian crab apple) and Malus prunifolia (plum-leaved crab apple).[2] It is being studied for its resistance potential to fire blight.[3] Known for its attractive fruit that remain on the tree well into winter, its cultivar 'Red Sentinel' has gained the Royal Horticultural Society's Award of Garden Merit as an ornamental.[4]
