This State holds the largest underground water supply in the country. Not to mention, it also has more miles of river than any other region in the United States. This is perhaps why there is such a massive existence of flora and fauna, and forest resources in this particular region. Additionally, the abundance of water supply is also one of the main reasons why Nebraska is known as the tree planter’s State.
Today, there are around three acres of land in the State that is filled with trees. You can find over thirteen million trees in Nebraska. However, not all of these trees are safe. Considering the massive amount of trees in the State, there are also a considerable number of trees and plants here that are dangerous since they may carry poison.
It is essential for those visiting or living in the State to be aware of such plants in order to stay safe and avoid them. This guide takes a thorough look into Nebraska’s poisonous plants.
1. Death Camas (toxicoscordion venenosum)
This species of flowering plant is perhaps one of the most dangerous ones you can find in Nebraska. It is typically grown in drylands where water is scarce. The death camas, which are also known as meadow death camas, are completely toxic since all parts of the plant are poisonous to humans and animals alike. If both consume too much of the plant, it can be fatal for them.
2. Dwarf Milkweed (Asclepias speciosa)
These are yet another species of poisonous plants that grow on dry soils. You can also find the dwarf milkweed in meadows and waste areas. All species of this plant, whether with narrow or broad leaves, are considered to be dangerous. They contain toxic substances within them, which is why consumption by humans and animals can lead to a detrimental negative impact on the digestive, respiratory, and nervous systems. As a result, overconsumption of this plant can even lead to muscle tremors and seizures.
3. Lambert Crazyweed (Oxytropis lambertii)
Lambert’s crazyweed, which is also known as purple Locoweed, is a gorgeous flower plant found in Nebraska. You can mainly find it in the foothills of mountains. However, it should be noted that this plant is quite dangerous and should not be planted within or around homes. These plants can be poisonous at all times of the year, including when they are dried. Once consumed, they can impair your body’s cells. If a lactating female animal has consumed the plant, then the poisonous effects would also be passed down to the children through the milk.
4. Nebraska Lupine (Lupinus plattensis)
This gorgeous wildflower can be a great addition to your landscaping. Since it thrives in dry soils, the Nebraska lupine is grown throughout the State.

7. Riddell Groundsel (senecio riddellii)
These plants that have bright green leaves and yellow flowers can be pretty dangerous because they can poison cattle, horses, and sheep. In fact, all species of this plant can be poisonous to all types of cattle. Lactating or pregnant animals can also transfer the poisonous effects to their offspring, making this plant even more dangerous.
8. Arrowgrass (Triglochin Maritima)
This perennial plant grows in wet areas and meadows throughout Nebraska. Since they look similar to hay, people may cut them out for feeding livestock. However, this can be poisonous to them. Not all forms of Arrowgrass cause poisoning; only the ones with stunted growth tend to be poisonous. Cattle and sheep can be severely affected by this plant, which can be life-threatening to them. It can also lead to other side effects like diarrhea, increased salivation, convulsions, and coma.
9. Poison Sumac (Toxicodendron vernix)
This is a small tree or wooden shrub grown in swampy and wet parts of Nebraska. The plant is considered to be toxic and dangerous because it is more allergen than poison ivy. Hence, consumption or contact with the poison sumac can lead to itching, discomfort, and inflammation that persist for days. The poison sumac can be identified through its low height, bright green or orange leaves, small yellow-green flowers, and sometimes, whitish waxy droops that drop loosely from its stalks.
10. Prairie Larkspur (Delphinium carolinianum)
This is a beautiful, slender, and upright perennial that is found in various parts of the State. It typically features pale blue or white flowers, spurred flowers, and basal leaves. No part of the prairie Larkspur should be consumed because it is pretty dangerous and potentially life-threatening. Consumption of this plant can prove to be fatal to both animals and humans.

Larger and older species of this plant may be more dangerous since they can cause chronic toxicity.
12. Woolly Locoweed (astragalus mollissimus)
This is a perennial plant from the legume family. It originated in Colorado but can also be found on drylands in Nebraska. The Wooly Locoweed is particularly dangerous for livestock and cattle. Consumption of this plant can make these animals go ‘loco,’ which can also be fatal for them. However, this is only true for a select species of this plant. Others might not be this toxic.
13. Wisteria (Wisteria)
Wisteria is a poisonous plant, although the poisonous effects may vary. Severe poisoning is not common, but exposure to a few seeds can actually lead to detrimental results. For example, side effects of consumption of the Wisteria include diarrhea, oral burning, vomiting, and stomach pain. Other symptoms also include dizziness and confusion.
