Hardiness: To Zone 3 (Winters as cold as -40 degrees F
Flowers: May, June, July, August, and September
Planting: Plant with 12” to 24” above the pot
Planting instructions: Soil used for planting should be damp. For hardy water lilies, the rhizome should be placed so that the growing point is directed toward the center and at a slight angle. Look for buds or "eyes," similar to what would be found on a potato to determine which end is the growing point. This is done so that it can grow across the center of the pot. After the rhizome is in place, cover it with soil so that the growing point is just barely above soil level.
