Corylus avellana ‘Contorta’, a deciduous plant, that twists itself into various shapes, therefore it can add an interesting sculptural accent to the rooftop garden.

The leaves of this plant are rather big for such a small shrub, which by the way can be up to 10 feet tall. However, this plant can be quite invasive so it is best to check the local gardening restrictions.
