Plants Poisonous to Koi

[ChrisC]

Can anyone refer me to a list (if it exists) of plants poisonous to koi which should not be planted anywhere near a pond?

I am planning my greenhouse pond and want to avoid preventable mistakes.....

Toxic Plants

One pollutant area that is often overlooked by pond keepers has to do with the plants in the pond or those that are part of the landscaping around (and over) the pond. The seeds of most plants can swell and plug up the digestive tract of the Koi.
