Also known as ‘Hall’s Giant’, the Giant in the name refers to the large-sized nuts and heavy bearing nature of this fruiting variety of cob nut, rather than its overall size. Corylus ‘Merveille De Bollwiller’ is actually a usefully compact variety, reaching only about 3m. It’s an old, late-season cultivar originating in France, that produces high yields of medium to large, glossy brown nuts. Although the nuts are not as large as some modern varieties they are noted for their excellent flavour. They are ready to harvest in October and can be eaten fresh or stored for later use. Attractive, pendulous yellow catkins hang from bare branches in late winter providing additional interest and an early source of food for pollinators. Partially self-fertile, Corylus ‘Merveille De Bollwiller’ produces the best crops when it has at least one different pollination partner including wild hazel. It is a good pollinator of other varieties. Height and spread: 3m (10ft).
