What Does Poison Ivy Look Like
Poison ivy is a woody plant that can grow as a vine, shrub or ground cover. Its most famous feature is the phrase:
“Leaves of three, let it be.”
Each poison ivy leaf cluster has three leaflets attached to one stem. These leaflets are almond shaped with pointed tips. The edges may be smooth or slightly toothed.
Common visual signs include
- Three shiny green leaflets in spring and summer
- Reddish tinted leaves in early spring
- Bright red, orange or yellow leaves in fall
