Transformational Gardening

Disclaimer: Foraging can be fun, rewarding and provide health benefits. As a novice forager, I will be sharing my foraging experiences. However, in order to be safe, always consult with local foraging experts and guidebooks before beginning foraging. Children should learn to forage safely by being guided by experienced adults. Never ingest anything unless you are certain of the identification and safety of the plant. Some plant species are inedible and some are poisonous.

American Elm (Ulmus americana): Images

Date Location Notes Images
May 22, 2012 Southeastern, New Hampshire I am still fairly weak in my knowledge of trees and find it challenging to identify trees that seem easy for others to learn. This one appears to be American Elm. Elm tree leaves have double-serrated teeth, meaning that the teeth have smaller teeth on them. The main teeth on these leaves are so large that you have to look closely to see the smaller teeth within the bigger teeth. Leaves are alternate and have uneven bases.

One of the most certain ways to tell the difference between American Elm and Slipper Elm (Ulmus rubra) is the lateral veins on the American Elm leaf blade do not fork (branch) until near the edge (margin) of the leaf. (In rare cases, one lateral vein may have a fork well before the edge on an American Elm leaf.) On a Slipper Elm leaf, the there will be at least two and sometimes many forks well before the edge of the leaf. In addition, Slipper Elm leaves tend to be rough on the top of the leaf and much more densely hairy on the back of the leaf. Buds and twigs on the American Elm tend to be brownish while twigs on the Slippery Elm are grayish and the buds are rusty brown to black. Finally, cutting a cross section of bark from American Elm will show an alternating pale and dark bands which are not seen in Slippery Elm bark.
