In this post, we look at some of the poisonous wild flowers to be wary of when it comes to landscaping.

1. Angel’s trumpet

Angel’s trumpet is one of the seven species of flowering plants classified in the family,Solanaceae. Often referred to as Brugmansia, the plant is amongst the most toxic ornamental plants. Every part of the plant, including the flowers, leaves, seeds, and even the roots contain toxic alkaloids that are widely synthesized into modern medicinal compounds.

Angels trumpet grows quickly in a warm climate. If the plant has a fair amount of sun, it tends to produce blooms all summer long. Although the blooms can be quite attractive, Angel’s trumpet is not the right plant for your backyard, especially if you have kids or animals that might feed on the seeds or leaves.

2. Deadly Nightshade

Another deadly plant you should not think about planting in your backyard is the deadly nightshade. The perennial plant features long and thin branches, while the leaves are oval-shape. Deadly nightshade grows on stalks in an alternate pattern.

Deadly nightshade has attractive berries, but they are poisonous. If ingested, deadly nightshade could cause blurred vision, rashes, headaches, and slurred speech. Therefore, avoid growing deadly nightshade in your backyard, as the berries can be tempting to your kids and pets.
