Chestnut Comparison Chart

Leaf taper to stemstraightcurvedcurvedcurvedstraightBe aware that all chestnuts can cross-pollinate, so that the chestnut you are trying to identify may actually be a mix of two or more different types of chestnuts, known as a hybrid.

We can attempt to identify your chestnut, if you are unable to do so, by means of a leaf and twig sample.

Please press one or two fresh leaves between cardboard with a 4-6 inch twig. Do not use plastic unless it is perforated or the leaves will mold. Crushed and bent leaves will not be in good enough condition to positively analyze.
