While you are out on the trails you are going to see so many different plants. But not all plants are friendly. Some plants should have a little sign on them saying “don’t touch me!” However, they don’t and because of this we need to know which are the plants we should give a wide berth and only look at them from afar. I often think why make plants that if I touch them will make me remember them for hours or days to come. That’s not very nice of them.
Most Common Plants:
Poison Ivy, Poison Oak, and Poison Sumac
These are the ones that most people know about and probably have had a run in while in the wild. These plants create an oil and when we touch them it irritates our skin, creates a rash, and becomes itchy. Fun fact almost everyone is allergic to these plants. If you are one of the lucky ones that isn’t, just keep that a secret.
Poison Ivy: has three leaflets on each leaf and grows as a bush or vine.
Poison Oak: has three leaflets on each leaf, with rounded tips, and grows like a shrub or vine.
Poison Sumac: leaves have clusters of seven to thirteen leaflets arranged in pairs and grows as a tree.
Stinging Nettle
These plants have small hairs on the leaves and stems that irritate the skin and produces the stinging sensation. When the hair that acts like needles touch you, they put acid into your skin which will cause small red stinging bumps. This acid is the same as ant bites.
Stinging Nettle: leaves are heart-shaped with serrated edges and tapered tips as a shrub.

Other Plants to Watch For:
