How do you know if a plant in your garden is poison sumac?
SarahChristensen
1. Look for poison sumac in very moist or flooded soils such as marshes or wooded swamps. If the surrounding area is relatively dry, you can be sure that the plant you are examining is not poison sumac.
2. Measure the plant. Fully mature, its height will range between 6 and 20 feet (2 - 6 m
3. Look for branches all along the trunk. Poison sumac can be considered either a woody shrub or a small tree. It produces branches at all heights along its trunk, resulting in an overall form that is full and rounded
4. Look for a pinnate leaf structure. This means that each stem contains 2 parallel rows of leaves on either side with a single leaf at the end. These pinnate structures will contain between 7 and 13 leaves
5. Look at the oval or oblong shape of the leaves, tapering to a fine point at the tip. The leaf edges will have a very subtle undulation. They should also have an upward orientation, with the axis angled towards the tip of the stem.
6. Measure the length of the leaves. Leaves typically range between 2 and 4 inches (5 - 10 cm) in length.
7. Look for bright green or bright red leaves. Poison sumac leaves are bright green throughout the warmer months, turning to a bright red in the fall before falling away in the winter.
8. Look for a smooth, matte appearance and texture on the leaves. The leaves are usually hairless on both sides, but sometimes have a fuzzy layer of very small hairs on the underside.
9. Observe the stems and branches of the plant. The stems of the poison sumac are hairless and smooth. They typically have a dark brown color, flecked with even darker spots.
10. Look for white or greenish-white berries hanging in clusters. The poison sumac produces berries that are very similar to those produced by poison ivy or poison oak. The berries are quite small. They appear in spring and typically last through the beginning of winter, when they will dry up and fall away.
11. Look for small, greenish-yellow flowers. Poison sumac flowers are, like the fruit, very similar to those of poison ivy and poison oak.

Is poison sumac contagious?

How does poison ivy rash start out?
Typically several hours to about a day after contact with the poison ivy plant (the leaves or the vine) or oil from the plant. Note that you can get a poison ivy rash if someone who is not sensitive touches the plant and then gets urushiol (the oil that causes a reaction in some people to poison ivy, poison oak, or poison sumac) on your skin. You can even get a poison ivy rash from petting your dog or cat after it has brushed up against a poison ivy plant. Also note that the vines and the leaves can contain urushiol long after the plant has died, and burning poison ivy foliage can release the urushiol into the air, potentially causing a poison ivy rash on the inside of your lungs. If you know that you have come in contact with poison ivy but have not yet developed the rash, you may be able to prevent or reduce the rash by washing in cold water with special soap that binds to the urushiol. However, washing in warm or hot water will spread the urushiol across a larger area of skin.

Does poison sumac grow in pa?
Very uncommonly in bogs and wetlands (mostly a Southern tree). A botany professor at West Virginia University told me he has looked for it for years in both PA and WV and has never found it. I would be skeptical of most people who claim to know its whereabouts.
