Does poison ivy grow on a vine?

Poison ivy plant growing on a vine.

Identifying poison ivy is an essential skill to develop whether you love the outdoors, work outside, or are an avid gardener. The poison ivy plant, while having the familiar characteristics of leaves of three, can look a bit different depending on the season and geography. Besides the fact that it has similar poisonous relatives that do not have this characteristic, poison ivy can also grow in deceiving ways.

What makes poison ivy and its relatives dangerous?

Poison ivy, poison sumac, and poison oak—three plants you’ll have to look out for when outdoors—contain oil that causes an allergic reaction that develops into a nasty rash. This rash lasts from days to weeks, sometimes needing special treatment. The oil is known as urushiol, and its structure includes molecules known as haptens, which bind to skin cells. Nothing happens to the affected skin cells, but your immune system will recognize it as a threat and start attacking it along with the cells surrounding it, attempting to stop what would have otherwise been a relatively harmless bond.

Identifying the dangerous plant

There is an old saying, “leaves of three, leave them be,” which is reasonably accurate. While following the expression will usually help you avoid poison oak or ivy, poison sumac grows with seven to fifteen leaves on long, red-colored stems. That said, even poison ivy can grow in ways that could deceive you. The following are the different ways the plant grows:

  • A single plant - This is usually what you look out for. This is how poison ivy grows before it spreads.
  • A shrub - Poison ivy can grow on top of itself, creating a bush or shrub-like appearance. Always be careful when walking through bushes.
  • As a vine - The plant crawls as a vine, sometimes covering the whole ground and sometimes as a wall of greenery.
  • Like tree leaves - There are times when the plant vine grows on trees, climbing up and branching all over, making it look like tree leaves.
