About
Corylus maxima 'Gunslebert' is a sizable shrub that can reach up to 6 meters in height if left untrimmed. It features wide, textured leaves and produces yellow-brown catkins during late winter or early spring. In early to mid-autumn, it bears clusters of nuts enclosed in pale green husks. This filbert variety is known for its ability to yield large, flavorful nuts relatively early in its life, with improved production when cross-pollinated with another variety.
