Bog Plants - Water Iris
Irises are among the most favored of the bog plants. Their foliage is attractive and is good as a backdrop or as an adjunct to the other plants in the bog. Their flowers have an obvious appeal, being among the most exotic flowers in the hobby. They are useful as filtering agents in ponds and can be grown in any moist area.
Louisiana Iris can be planted along the ponds edge or directly in the water itself. They should be planted in shallow water, preferably in a container that is wider than it is deep, i.e., a kitty litter tray. In this way, the plant can spread as it wants to and is not as likely to overgrow the pot as it would be if it were planted in a tall, narrow container.
Iris pseudacorus, on the other hand, does just fine if started out in normal pot. It will quickly overgrow the pot and will act as a very effective filter if the water is made to flow through the extensive root system that develops. All of the water Irises do best if cut back and thinned out every two years, or so, and if the dead leaves are not allowed to accumulate.
