How deep do i put an iris louisiana knock out in my wader garden

Question

i just bought an iris louisiana knock out for my water garden and don't know deep the plant should be.

Answer 1

  just read that the roots could start rotting if they grow outward into deeper water and don't reach any soil to root in, so I'd plant it in a shallower area of you pond so the leaves will be above water while the rhizomes have plenty of room to spread horizontaly through the substrate.
