Hello! If you could kindly take a moment to select your state we can instantly remove any listed invasive illegal plants in that state from view Thank you!
A few species and crosses of Iris can be grown in shallow water, along creek embankments, in wet soil. Iris that can be submerged in up to 4 inches below water are Louisiana Iris cultivars, laevigata Iris cultivars, pseudatata iris, & flag Irises. Pseudatata iris, a new cross of species also is fine with being submerged a few inches. The very beautiful Japanese ensata iris varieties love moist boggy soil but won't tolerate submersion more than 2 months a year. Divide your pond Iris in the fall for low to no mortality. All of our iris except laevigata varieties can grow outside the pond if watered a few times per week.
