Plants That Look Like Poison Hemlock

Having to deal with poison hemlock in your yard is not a fun experience. It is extremely invasive, causing damage to your yard, as well as to your health. There are several plants that look like poison hemlock, but they are not actually poison.

Western Water Hemlock

Often mistaken for an edible plant, Water Hemlock is an extremely poisonous plant that can kill humans and animals. In addition to its deadly leaves and seeds, its toxic roots can kill horses, cows and cattle. The seeds can remain viable in the soil for three years or more.

Queen Anne’s Lace

Despite the similarities, there are a few differences between Queen Anne’s Lace plants and poison hemlock. For one thing, Queen Anne’s Lace isn’t a true native to North America. In fact, it was introduced to the United States by early European settlers. This makes it a weed, and it can be found in disturbed areas such as pastures.

The first step in identifying a plant is to look for its fuzzy stem. You can also look for a purple flower on the stem. If the stem has purple spots, then you know you have Poison Hemlock.

In addition to the obvious difference, you will also notice that the leaves of the two plants are different. The leaves of Queen Anne’s Lace have hair on them. However, the leaves of poison hemlock have no hair.

In addition, the flowers of Queen Anne’s Lace have a flat shape, whereas the flowers of poison hemlock are round. This makes it easier for you to tell the difference between the two.

You can also tell the difference between these plants by the color of the umbel. The umbel of Queen Anne’s Lace is reddish, and the center of the cluster is often a purplish or reddish flower. On the other hand, the umbel of poison hemlock has a flat shape, and the center of the cluster is usually a purple flower.

You should also look for the bracts, which are found at the base of the flower. These bracts are a cup-shaped nest that encircles the flower. They have a fern-like appearance.

The roots of Queen Anne’s Lace are edible, and they can be dried and ground into a fine powder. They aren’t very tasty, though. You can use them as a dye for your clothing. They are a good wildflower to pick for bouquets.

Wild parsnip

Despite its name, the wild parsnip is not a hemlock. It is actually a biennial plant that can grow up to 5 feet tall. It is native to Europe and Asia. It can also grow in Canada and other parts of the United States.

The flowers of the wild parsnip are yellow. They have five petals that are curved inward. They form an umbrella-shaped cluster. They are three to eight inches wide. The stalks of the flowers are short and rounded. They are commonly confused with Queen Anne’s Lace.

The seeds are large straw to light brown. They are round to oval, with narrow wings. They are usually eaten by small mammals.

The wild parsnip grows in areas with disturbed soils. They are common in the northern United States and southern Canada. They are regulated in Illinois, Wisconsin, and Tennessee.

The sap from the wild parsnip can cause blistering. This is caused by the toxin furanocoumarin, which is found in all parts of the plant. It can also cause phytophotodermatitis, which causes reddening of the skin. Symptoms start after 24 hours of exposure, but the severity of the blistering peaks after 48 to 72 hours.

The root of the wild parsnip is smooth and cylindrical. It produces an essential oil that contains a high percentage of Myristicine, a strong human hallucinogen. The wild parsnip is considered to be more aromatic than the domesticated version.

The leaves of the wild parsnip are generally pinnately compound with saw-toothed margins. The lower leaves have short stems.

The wild parsnip is thought to be an escapee from the parsnip originally under cultivation. It is a member of the Apiaceae family, which includes the carrots and angelica.

Wild carrot

Despite its name, the wild carrot looks very similar to the poison hemlock. Both belong to the Apiaceae family. This plant family includes several edible species and several deadly ones.

The wild carrot has fine leaves that are pinnately lobed. It grows on well-drained soils and in full sunlight. The stem is hollow, hairy and often reddish purple. The flowers are tiny and dainty.

The wild carrot is considered a Class C noxious weed. Although the wild carrot has been used for medicinal purposes, the FDA has not approved any products that contain wild carrot. It has been known to cause skin irritation and rashes. For sensitive individuals, it may also interfere with blood pressure control during surgery. It is recommended not to consume it during pregnancy.

The wild carrot is a biennial plant. In the second year, it produces an umbel of small white flowers. This is followed by another umbel the following year. The inflorescence grows on a tall stem. The flower clusters last till September.

The wild carrot is commonly found in the eastern part of the U.S. It can be found growing in cultivated fields and community gardens. However, it can be a nuisance to livestock. It has been known to taint the milk of cows.

The wild carrot is a useful plant for its ability to relieve gas and indigestion. It also has anti-inflammatory and diuretic properties. It can help in preventing kidney stones. Its seeds are also believed to have contraceptive and anti-fertility properties. It was brought to the US by early colonists. It is also a popular medicinal plant.

The wild carrot’s roots have an off-putting odor that resembles the smell of mouse urine. The sap of the wild carrot is also irritating to the skin. It is best to mow the plants before they go to seed to prevent them from spreading.
