So here is what I did. I compiled a list of all poisonous plants. My thinking is that if you have a pond, small children and pets, fish, dogs or cats, then you need to be aware of plants that are fatal/toxic/poisonous in, near, around your pond or landscaped yard.

I am very interested in this topic personally, so what I would like you to do is if you have first hand knowledge, that by eating a plant that your fish died, email me. I will be keeping a list of plants on hand and some time in the future I will update this list.

Here is a classic example of what I am talking about. Tomato plants are listed as the leaves being poisonous. I kept a tomato plant in my pond, last year as an experiment. My fish kept the leaves chewed off and we enjoyed the tomatoes that grew in the pond. I have to believe tomato plant leaves are not poisonous to fish while they are poisonous to humans. I have also kept some of the water plants that are listed as being poisonous in my pond over the years. Cardinal flower, Taro, and Calla in my pond are just a few that are on the list of being poisonous. While I have not seen my fish eat the roots of these plants, the roots are readily available for them to eat should they so desire. I have not found them to be harmful to my fish.

So here is the list. If you do not see a particular plant on this list, the omission DOES NOT necessarily indicate the plant is not poisonous.
