Leaf Taper to Stem

Be aware that all chest nuts 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 re unable to do so by means of a leaf and twig sample.

 

Pleass press one or two fresh leaves between cardboard with a 4-6 inch twig. Do no 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.
