shellbark hickory
shellbark hickory - Carya laciniosa
The nuts of the shellbark hickory are often eaten raw or baked in pies, similar to pecans. Due to the extreme palatability of the fruit, the shellbark hickory relies on animals for seed dispersal, with everything from foxes, deer, muskrats, and even wild turkeys seeking out their fat- and protein-rich fruits. Shellbark hickory can be difficult to distinguish from shagback hickory, but it is generally much larger, in overall size, buds, nuts, and leaves. Shagbark hickory is also much more common in Ontario.
Uncommon, but preferring valleys and rich moist soils, even where inundated for a short period of time. The shellbark hickory is rarely cultivated.
The shellbark hickory fruit is large, round and somewhat flattened. Its green husk is thick with a large thick shelled nut on the inside. The central stalk of the compound leaf often remains into winter after leaflets have fallen.
Twigs light orange and hairy. In regards to the bark of the shellbark hickory, the Latin term lacinia means “cut into shreds”, which in this case references the loose plates of bark that peel and hang from the mature tree.
