Maybe you will not find all ten of these poisonous plants growing in your garden, but I am sure that many will be there. So many of our common garden flowers and shrubs can cause serious harm if eaten so it is a good idea to be aware of which they are. I found this list of the top 10 poisonous garden plants on the Gardening Know How website.

Not to freak anyone out, but the garden can contain many surprising dangers. Some of our most common ornamental plants and wild volunteers are actually poisonous and have the capacity to be harmful to humans or our pets. It is important to be aware of the potential dangers in your garden to protect yourself and your family from accidents.
Here are the top 10 poisonous plants in or around the home:
1. Apple.

In the number one spot, we have the apple. Yep, you read correctly. Apples (and apricots as well) have extremely toxic seeds. Of course, you would have to eat more than an apple a day to receive any adverse effects, but they are listed as majorly toxic on the Poison Control?s plant list.
2. Delphinium.

Most of us are familiar with these perennials, which produce lovely blue flower spikes that tower over sweet basal rosettes of leaves. The delphinium plant has an extremely toxic diterpenoid alkaloids in all parts of the plant, however, and are dangerous to both domestic and wild animals, as well as humans.
3. Rhododendron.

Our third culprit is found in gardens across the nation. It is Rhododendron, a native plant that is found wild in many of our forests and clearings.
4. Oleander.

Oleander is primarily found in the warmer regions of the country, but it has the ability to cause death with very small doses ingested. This fatal beauty has long been a solution plant for unhappily married people over the centuries.
