View prices and availability
Small tree with a spherical crown up to 5 -6 m in height and width. Annual pruning keeps the crown compact. If it is not clipped, the tree develops an umbellate crown. Then it can sometimes attain a height of up to 8 m and develop a characteristic manner of growth. 'Umbraculifera' is always grafted on a stem, at heights between 1.80 m and 2.50 m. The branches do not have any thorns. The green leaves are smaller than those of the species, as are the leaf segments. Leafs out late and keeps its leaves long into the autumn. Does not produce flowers and grows well in light, calcareous soil. Winter hardiness zone: 5a
