Crataegus monogyna 'Stricta' forms a more or less columnar tree with branches that hang down somewhat at a later age. Height up to 10 m, breadth up to 3 m. The lobed, deeply incised leaves are dark green and turn yellow in the autumn. Flower umbels appear in May with single white and sweetly scented florets. In the autumn the unremarkable, small, dull red fruits emerge. Because of its columnar growth this tree is suitable for narrow streets and small gardens. It does not stand up to wet soil. In dry summers its leaves can suffer from burn. Winter hardiness zone: 5a
