Both are required in a stand for fruit production. The branches are grey and spiny with silvery-white leaves. Small yellowish flowers appear in spring before the leaves and attractive yellowish-orange berries follow. The berries remain on the tree through winter. Deer browse seabuckthorn and the fruit is an important source of winter food for pheasants and other game birds.
Siberian crabapple is a vigorous, winter and drought hardy tree.
It was introduced into Canada, and it is well adapted to a wide range of soils and climatic conditions. The tree has a large spreading crown and may reach a height of 7 to 9 metres given favorable conditions. White showy flowers are produced in early spring and the tree bears small, berrylike red or yellow fruit later in the season. Siberian crabapple is susceptible to fire blight and does not compete well with weeds. The dense growth form of the Siberian crabapple provides high quality cover for roosting, loafing and nesting birds.
