Whether you have a yard that’s been infested with poison hemlock or you are just looking for a new plant, you might be wondering which plants look like poison hemlock. Below is a list of plants that look like poison hemlock, including some of the signs and symptoms to look out for and how to keep your yard free from these dangerous plants.

It’s green in color

Often mistaken for a wild carrot, poison hemlock is a deadly invasive weed that can affect both humans and animals. Its name comes from the poisonous alkaloids found in the plant. It is not native to North America, but it is spreading rapidly across the country.

Poison hemlock is an erect biennial weed. It grows to a height of six to ten feet. The plant is native to North Africa, Europe, and Asia. It can be found growing in a variety of soil types. Depending on its growing conditions, it can have different concentrations of toxins.

Its leaves are glossy green and fern-like. They are divided into several layers and are serrated. They have a pungent smell when crushed.

Poison hemlock is native to western Asia, Europe, and northern Africa. It was introduced to North America in the 1800s as an ornamental plant. It has now spread across most of the United States. It is considered to be a noxious weed and is found on public lands and private property. It is especially toxic to livestock.

In the first growing season, poison hemlock produces a rosette of dark green leaves. In the second year, it produces white umbel flowers. The fruit is egg-shaped, two to three mm wide, and contains only one seed.

The seeds are oval shaped, light brown in color, and wavy ridged. The fruit contains the same toxins found in the leaves.

It has a fern-like shape

Originally from the Eurasia region, poison hemlock is now a widely spreading plant in North America. In fact, it is now native to almost all of the United States. It can be found in most Canadian provinces, and has naturalized in other areas.

Poison hemlock is a biennial plant, meaning that it comes back each year. It is found in wet areas, including rivers, creeks, and irrigation ditches. It can be dangerous to both humans and animals. In addition, it produces a musty, alkaloid-laden odor.

The first year, the plant forms a rosette of leaves. The second year, it forms a tall flowering stalk. The stems are hollow and hairless, and the leaves are hairless and fern-like.

The leaves range in size from eight to sixteen inches long. They are triangular in shape and divided into narrow segments. When crushed, they emit a rank odor.

The flowers of poison hemlock are white and appear in clusters on the stem. They resemble fennel and Queen Anne’s lace. The flower clusters are umbrella-shaped. They bloom in the late spring or early summer.

The fruit of poison hemlock is egg-shaped. The seeds are round, and lined with vertical wavy ribs. They can stay viable in the soil for up to three years.

Poison hemlock is toxic to humans and animals. Symptoms appear within twenty minutes to three hours of exposure. In addition, it is extremely toxic to the respiratory system.

It has a more rounded shape than Queen Anne’s Lace

Unlike Queen Anne’s Lace, Poison Hemlock is an edible plant, but is also deadly to animals. Both plants are members of the Apiaceae family and have similar appearances. Despite their similarities, you’ll need to know more to identify them.

Queen Anne’s Lace is a herbaceous plant that grows along the sides of highways and railroad tracks. It also grows along disturbed areas. The root is a thickened tuber. It is edible raw or cooked and has a pleasant carrot-like scent. The flowers of the plant are edible, but the seeds are highly poisonous. The flowers can be made into jelly.

The leaves of Queen Anne’s Lace are lanceolate, with rounded serrations at the tip. They are about 2 to 4 inches long and have hairs on the undersides. The stem is hairy. It is also known as the wild carrot.

The flowers of Queen Anne’s Lace are white and lacy. They bloom in the second year of growth. The flowers taste like honey. The head of the flower turns color when exposed to dyed water.

Poison Hemlock, on the other hand, grows up to ten feet high. It has purple blotches on the stem and leaves, and has an umbrella-shaped flower. It is in the carrot family and has purple spots on the stem. The flowers grow in clusters.

The stems of Queen Anne’s Lace have short hairs, while the stems of Poison Hemlock are smooth and hairless. The stems of both plants have purple spots, but Poison Hemlock has a more rounded shape.

It spreads via seeds

Known as hemlock, this biennial plant is native to Europe and North Africa. In the United States, it is a common invasive weed in pastures, roadsides, and fields.

Like other plants, poison hemlock is highly toxic to both humans and animals. When ingested, it can cause respiratory paralysis, muscle weakness, and dilated pupils. Symptoms usually appear within an hour.

Poison hemlock grows in moist soil and is usually found in sunny or partially shaded areas. It produces seeds that grow into many new plants.

To control poison hemlock, the United States Department of Agriculture (USDA) offers a variety of approaches. Some methods involve applying herbicides. While these methods are effective, they do not prevent the seeds from germinating.

Another method involves digging up poison hemlock plants. If the plant is in a rosette, you may need a shovel or trowel to remove the plant. However, if the plant is not in a rosette, you should avoid contact with the plant.

When you remove poison hemlock, you should wear protective clothing. Poison hemlock sap is toxic, and it can cause blisters, welts, and a painful rash.

To prevent poison hemlock from reproducing, it is best to begin control efforts early. When the plant is still young, it can be easily controlled. However, if the infestation has spread, it is too late for control.

Poison hemlock is a noxious weed and is deadly to humans, animals, and livestock. It spreads via seeds, water, and wildlife. It is a serious threat to public health, especially since it can be confused with other plants.

Symptoms of poison hemlock poisoning

Symptoms of poison hemlock poisoning include dilated pupils, trembling, dilation of the throat, respiratory paralysis, and weakness. The poison can enter the body through the nose, eyes, mouth, and lungs.

When an animal ingests poison hemlock, symptoms typically occur within two hours. If an animal’s kidneys are damaged, rhabdomyolisis may occur. If the animal’s respiratory system is damaged, it can die within one to three hours after exposure.

In one case, a 3-year-old border collie mix began chewing on water hemlock. She began to show signs of poisoning within an hour, including hypersalivation, tremor in the mouth, and ataxia.

In another case, a 6-year-old girl went to the emergency department with a burning sensation in her mouth. She also had a tremor in her hands, ataxia, and hypersalivation.

While there are no antidotes to poison hemlock, there are some treatments for less serious poisoning. A person who develops a less serious hemlock poisoning may benefit from early stimulants, such as a mineral oil tube inserted into the stomach. A veterinarian may also take a sample of blood and urinalysis to assess the patient’s biochemistry profile.

In most cases, a poison-hemlock ingestion is fatal. If an animal eats poison hemlock, the animal may develop fetal deformities or cleft palate. The animal may also have parasympathetic symptoms.

The first step in treating a poison-hemlock ingestion is removing the horse from the source of the poison. Once the horse is out of the plant, it is important to protect the remainder of the herd from further exposure.
