Corylus maxima 'PURPUREA' purple-leaved filbert

Filbert is a hazelnut species from S.E. Europe and S.W. Asia and exhibits a vigorously growing many-stemmed shrub with deciduous leaves. Purpurea is an old variety with deep maroon to near black leaves. They are 5-12 cm long, 4-10 cm wide, and during summer the colour of maturing leaves changes to dark green with burgundy hues, while new deep maroon leaves continue to grow at the ends of the branches.

From late winter appear showy, 5-10 cm long, male catkins in pale red to burnt pink colour, female catkins are only 1-3 cm. The plant is self-fertile. In late summer they are followed by elongated, edible nuts that you can only enjoy if the squirrels don't steal them all. Have you seen how fast they are? The nuts ripen in late September.

Purple-leaved filbert grows fast producing many canes from the roots, so rather than a shrub it can be called an impenetrable thicket with showy foliage. On the other hand, it cannot be considered weedy since all its canes grow from an enclosed space. Its size varies between 3 and 6 meters in height and width, so give it a deserved space. It is happy in a lawn and does not mind people trampling on its roots or mowing the grass above them.

It can be pruned almost anytime, but if you are growing it for fruit, cut it right after flowering not to lose the fruiting branches. Hazel is not demanding on the soil type. It grows almost everywhere, even in heavy and wet soils where it will exhibit slow growth and thinner branching. If you grow it for fruit, plant it in fertile, well-drained, preferably calcareous soil and provide a pollinator – another hazelnut nearby. For the deepest foliage colour place it in full sun. Fully hardy to about -34 °C.
