We are in Zone 5 in SW Ontario. Third year for the elephant ears. Have
green and purple.

Mine are planted in mesh baskets with rocks holding them in place. When the
roots really get going some of the rocks can be removed to make room for the
roots and base to expand. They are placed not far from the bottom of the
water fall and not fertilized. The roots extend out the mesh and use
available nutrients in the pond water. Last summer they grew massive and it
wasn't that great a summer. Also shady where mine are. When expecting bad
thunder storms with winds I drop deeper in the pond or lay them down.

In the fall I either move to a large pot of water and grow as a house plant
all winter or let them dry up. I needed to split one last year so let it
dry up; divided it; and restarted it about January. Don't put out until
danger of frost is past.
