Urushiol is found in the leaves, stems, and roots of poison ivy, oak, and sumac plants. You can even get a rash even in the winter so learning to identify these plants in all seasons is so important.
Learning to identify the poison ivy, oak, and sumac will help you avoid it. You can learn to identify these plants by their features and the areas where they grow.
1. Poison Ivy
The poison ivy is a shrub that shoots into a vine in growth. It has has a pointed tip in its smooth or notched leaves.
Poison ivy changes leaf colors through the changes of the seasons. It is green in the summer with green or yellow flowers and clusters of greenish to white berries.
In the springtime, the young leaves are reddish which turn red or yellow-orange in the fall. In winter, it sheds off its leaves but the roots and vines can still give you a bad rash.
The defining feature of the poison ivy though is its leaves forming in clusters of three with the middle leaf larger the leaves on the sides.
Be warned, “Leaves of three, leave them be,” is an old saying which rings true of poison ivy. Although there are other plants with leaves of three clusters, it’s better to be on the safe side.
You see, even the poison oak comes with leaves clustered in three. So just be wary of all plants which come in three leaves to be safe.
Poison ivy symptoms include itching, blisters, and redness. You may also have difficulty in breathing if you inhale the smoke from burning poison ivy.
2. Poison Oak
The poison oak is a woody shrub growing to about three feet tall, but also grows into a vine. It commonly grows throughout the country except in desert areas.
Again, the poison oak, much like the poison ivy also has leaves clustered in three. And like the poison ivy, there are some varieties with leaves clustered in five to seven, too.
Its distinct feature though is a scalloped, wavy form only less defined than oak tree leaves. But, while poison ivy leaves have notched sides with pointed tips, poison oak’s are smooth and rounded, also with pointed tips.
Poison oak is deciduous or loses its leaves during winter. In spring, it’s leaves are bright green, turning yellow-green or a shade of pink in the summer then turns yellow to brown during autumn.
Symptoms or a poison oak reaction include itchiness, redness, and swelling.
3. Poison Sumac
Poison sumac grows as a tall shrub or a small tree, growing to about 20 feet tall. Its distinct feature is elongated leaves, usually in clusters or pairing of 7 to 13 leaves.
You can find them growing in wet soil or swampy areas. That’s why the poison sumac is common in the midwest parts of the North and Southeast where the humidity is high.
Poison sumac also changes color throughout the seasons. In the springtime, it is bright orange in color, dark green in summer, and turns red-orange during autumn.
Other distinct features are the clusters or fruits it bears. It has also clusters of greenish-yellow flowers growing in the summer.
Poison sumac allergies are even worse than poison oak and poison ivy rash. Poison sumac rash symptoms include a burning sensation and watery blisters.
