Leaf Identification 101

Why is leaf identification important?

Leaf identification allows us to study the plants that inhabit our local environments and identify the uses and values of these plants. Because leaves are an easily observable part of the plant (similar to plants that flower or bear fruit), they give us quick access to a plant's health, climate, and other qualities.

People enjoy leaf identification for a number of reasons, such as its usefulness in foraging and gardening, and it can be used as a tool for educators teaching about conservation and environmentalism. Learning about leaves is also helpful for hikers and those who enjoy the outdoors as a way to avoid poisonous plants.

How to Identify Leaves

There are several things to consider when trying to identify leaves. We've broken it down into a few simple steps to make leaf indentification easier.

  1. Examine the shape of the leaf. Is it single (one leaf) or compound (made up of many smaller leaves)? Is it lobed (with peaks and valleys, like the shape of a hand) or unlobed? Are the edges smooth or toothed?
  2. Investigate the texture of the leaf. Is it broad and flat? Thin and scaly? These factors will help you identify what type of leaf you are looking at.
  3. Study the arrangements of the leaves on its stem. According to Bonnie L. Grant from Gardening Know How, "Some leaves grow opposite, some alternate, some in rosette forms and others in whorls...The arrangement gives part of the clue as to the species."
  4. Identify other important factors. You can also identify leaves by color and venation (the veins of the leaf). Some leaves, such as those with needle-like leaves such as conifers, have very distinct appearances.

How to Identify Poisonous Plants

You can protect yourself against poisonous plants by being aware of what they look like. (Good thing you have this helpful leaf identification chart to guide you!)

Most people who come into contact with poison ivy, poison oak, or poison sumac will develop an itchy red rash that can last for several weeks. Avoid direct contact with the leaves, stem, roots, or berries of these plants (even if a plant is dead).

If your shoes, clothing, pets, or tools come into contact with these poisonous plants, avoid touching them in the contaminated areas and wash them as soon as possible. If a contaminated object isn’t cleaned, you can still develop a rash from touching it years later!

If you have been in direct contact with a poisonous plant, wash the affected area as soon as possible. This can lessen the severity of the rash. Then try this poison ivy home remedy!

This is a brilliant little chart to have and is a great one to do with the kids as an adventure day out or to make it as a little competition with them. My Niece and Nephew had the best time doing this and seeking out the safe non poisonous ones

I am so glad to find this chart with the pictures of poison oak,posion ivy and sumac because we have a lot around our yard and I have to watch out for it when I garden and my grandkids play in the yard. These can be mistaken easily for good leaves. As a matter of fact my husband swore that a vine we had was kutzu but it is not.I took a picture on my phone of them so I know what to stay away from. Anyone else do the same?

This is a handy chart to learn and have around. It could also be used to create a fun game to play with the kids when camping or on a family outing. After looking over the chart, I assume not everyone reacts to the poisonous leaves. I came into close contact with all three as a child and never had a reaction of any kind.

This guide is so helpful! I know what poison ivy looks like but can never remember what poison oak or poison sumac looks like. Great if you live in a rural area!

Definitely needed before any camping or hiking trip!
