Like poison oak, poison sumac grows like a shrub or small tree. Poison oak grows like a shrub with leaves atop longer, upright stems. Poison ivy grows like a vine along the ground or up the sides of trees or structures. The growth habits of poison ivy and oak are different. Also, for poison ivy and oak, the juncture where the leaflet joins at the stem is often reddish. The difference with poison oak is the teeth appear rounded, more like a rounded or bulbous common oak leaf meanwhile, poison ivy teeth edges appear more pointy. They have teeth along the edges of the leaf. Each leaf (or, in this case, leaflet) is 2 to 8 inches long and 1 to 5 inches wide. They each look like they have three leaves per stem. Poison ivy and poison oak are more alike than poison sumac. When working around poison ivy, it's essential to wear gloves (wash the gloves and your clothes separately afterward from your other laundry) so that any residue you came in contact with isn't transmitted to your food, face, pets, other people, or any other surfaces.
It is possible to eradicate poison ivy safely, whether organically (manually) or with herbicides, but you must take extreme precautions, which might take several attempts. You should remove poison ivy from your property, so you don't accidentally make contact with it while gardening. The significant difference is box elder leaves, however, are arranged opposite each other, not alternating like poison ivy. Also, Virginia creeper vines are much less hairy than poison ivy vines.Īt first glance, box elder ( Acer negundo) seedlings grow as three leaflets, which can look like poison ivy. Similarly, both plants have a reddish center where the leaflets join. The difference between Virginia creeper and poison ivy is that it often grows in groupings of five leaflets. Virginia creeper ( Parthenocissus quinquefolia) is commonly mistaken for poison ivy since it's another vine that often grows in the same places. Poison ivy is not fussy about sun and soil conditions, which is one reason why it is such a successful weed. But it could be invasive in regions to which it has been introduced. Poison ivy is native to the eastern United States and eastern Canada therefore, by definition, it can't be considered invasive there, even though it spreads aggressively even in that region.
