Some plants have an extremely attractive appearance but are potentially dangerous.
1. The giant hollyhock tree
The giant tree has long, deeply split leaves that can grow up to 1.5m wide. The stems are bright green with dark spots all around. Its flowers are usually white or bluish-white, blooming in clusters like an umbrella.
When accidentally touching the sap from the leaves and exposed to sunlight, it is easy to leave painful blisters on the skin. If the sap accidentally gets into the eyes, it can cause permanent blindness. Often, this plant is mistaken for a wild carrot plant and you should be careful if you see this plant.
2. Beach apple tree
This plant has glossy green leaves, yellow flowers, and green or yellow-green fruit. At first glance, this fruit looks a lot like an apple, but all parts of the tree contain toxins and when its milky sap comes in contact with the skin, it can cause atopic dermatitis.
3. Poison oak tree
Poison oak contains an oil called urushiol, which is extremely toxic. If you come into direct contact with this substance or through animals or certain objects with oil, it can cause blisters, itchy bumps.
Poison oak leaves are easily confused with white oak and the two trees often grow side by side. For easy identification, poison oak leaves usually grow in clusters of 3, while white oak trees will grow single leaves.
4. Poison gardenia
Touching this plant can cause a rash and itching that lasts for weeks. So, just to be safe, you can tell it from the shape of the stem and leaves. The leaves of the plant have seasonal changes in color, elongated like feathers. In early spring, poison ivy leaves are bright orange, then turn dark green and red-orange in autumn.
In addition, there is another type of gardenia that is not poisonous at all. You can tell them apart from the shape of the fruit on the tree. Poisonous plants will have green berries and harmless plants will have crimson berries.
5. The “gentle” tree
Don’t be fooled by its name and slim form. Contact with this plant can cause intense itching and sharp pain. Some people have a strong reaction that will lead to skin discoloration within a few days. You can recognize this plant by its features: long stem, three serrated leaves, white flowers that bloom throughout spring and summer.
6. Gympie – Gympie
These large heart-shaped leaves have serrated margins. In addition, its trunk, fruit, and branches are also covered with stinging hairs. After touching this plant, you will experience an immediate itching sensation, followed by a burning sensation that lasts several days, even months.
7. Stinging nettle
The leaves and stems of the stinging nettle have many small hairs, exuding an allergic reaction when touched. Its leaves are soft, green in color, and clusters of flowers grow densely around the stem.
8. Poison ivy
The leaves, stems, and roots of poison ivy produce a resin that causes a rash, itching, and discomfort. In the spring, the leaves of this plant are red, in the summer they are green and in the fall they are bright yellow or red.
You can sometimes see poison ivy growing among the black raspberries. So, be careful when you see this plant.
