The two sides of the leaf may or may not be symmetrical. Leaves may be red or green, shiny or dull. The plants may have flower buds, flowers, or berries in dense clusters close to the vine.
According to the American Skin Association, as many as 50 million Americans have a poison ivy reaction each year. Urushiol sticks to skin, clothing, fur, gardening tools, and other surfaces when it comes into contact with them.
Washing the oil off your skin immediately after contact may prevent a rash from developing. Soap and water is effective, as are commercial poison ivy washes, but the key in either case is to wash the oil off quickly, before the allergic reaction begins. Following contact — or even potential contact — with poison ivy, you should also wash your clothing and footwear and any gear or equipment that could have touched the poison ivy plant.
Poison ivy loses its leaves in the winter and grows new ones in the spring. Young poison ivy leaves often start out dark red and shiny, then gradually turn green and less shiny over time. In addition to leaves, the poison ivy plant may grow clusters of small, green of flower buds in spring.
In summer most poison ivy leaves are green, although new leaves may still appear reddish at first, and the leaf edges and stems of the plant sometimes stay red.
Poison ivy vines often take over an area, crowding out other plants and creating a carpet of poison ivy. It can also weave itself in among other plants, sometimes covering an entire field of grasses or other low plants.
And it can create a wall of foliage on fences, abandoned buildings, or sunny rock outcroppings. Individuals who choose to wear shorts, short sleeves, or sandals outdoors in hot weather should look carefully before touching or walking through any greenery. Similarly, hikers and other outdoorspeople should stay on trails and be extra careful when stepping off the trail to heed the call of nature. Poison ivy is one of the first plants to change color in the fall, and its leaves can turn a brilliant red, yellow, or orange.
They can still give you a rash, just like green poison ivy leaves. In winter, poison ivy loses its leaves, but it can still cause a rash if you touch the hairy vines that remain.
Its leaves are pointed at the tip and grow in groups of three. In spring, the leaves are green, while in fall they turn reddish-orange. The plant also has small clusters of white berries, which it drops to reseed itself and grow larger.
These berries can be seen starting in spring all the way through to the end of winter. The problem with poison ivy is that it's very adaptable and grows in various ways, making it difficult to identify. That's why you should look for leaves that grow in clusters of three, which is the most defining characteristic of this plant.
Though most people think of it as a vine that grows upwards, clinging to a variety of surfaces, mainly because it does have "ivy" in the name, the fact is that poison ivy can also grow as a bush or even a single plant.
So, when attempting to identify poison ivy, make sure to look for three leaves with pointy tips that are loosely connected on each stem. The middle leaf tends to have a small stem, while the two side leaves grow off the vine. When looking from above, the leaves are a dark, waxy green, while from below they appear a light, fuzzy green. The waxiness makes the leaves appear shiny, but this isn't always an indicator as they can seem dull after rain. Most importantly, don't touch poison ivy when trying to identify it.
If in doubt, it's best to steer clear because getting just a little of the plant's oil on you can cause a very unpleasant rash. Ideally, you were successful in recognizing poison ivy and managed to avoid it, but this is not always possible. So, if you did come in contact with poison ivy, your best option is to use a cold compress on the affected area.
Calamine lotion, hydrocortisone cream or antihistamines can also be used to stop the itching. If the rash is on your face, close to your eyes, or covers a significant area of your body, visit one of our Urgent Care centers in the Greater Augusta County area.
Some individuals will have a more severe allergic reaction, in which case you may need emergency care immediately. Like poison ivy, poison oak can grow as a shrub or a climbing vine, and its leaves also grow in groups of three off the stem. Unlike poison ivy, though, the edges of the leaves have a wavy appearance and, as the name indicates, they look somewhat like oak leaves.
The tops of the leaves are usually glossy green, but they can be yellow, red or brown depending on the season and how healthy the plant is. The underside of the leaves appear more velvety and feature a lighter green color.
