This section contains only those plants which are true water irises. There are many irises (such as Iris siberica varieties, and Iris ensata/Iris kaempferi varieties), which will tolerate moist soil but which will die if placed permanently in a pond. They are therefore not true pond irises and we do not feature them here.
Planting depths mentioned on these pages refer to the depth of water over the crown of the plant (the depth of water over the soil level). Having less water than this does not matter, as long as the soil is not allowed to dry out. In order to get the best growth and greatest number of flowers, we recommend that you plant your irises in a sunny spot and, if they are in a pot, fertilise them once a year. Please note that irises are toxic to people and animals if ingested.
