About
Corylus avellana Purple Umbrella ('Jm 251' PBR) is a compact deciduous tree that reaches approximately 2 meters in height. It features a straight trunk that supports its distinctive umbrella-shaped weeping form. In spring, the new foliage emerges in a dark purple hue, transitioning to red-purple and then reddish-green throughout the summer months. As autumn approaches, the leaves turn a dark yellow before they drop.
