I have tons of the pink "naked ladies or surprise lilies" Last year I planted 4 of the red ones and they made it through our winter. The red is what I am looking for. We are going on a rescue of tons of the naked ladies in a week or 2. The house was torn down and the lady had tons of flowers. We have dug up lots of her(she died a year ago) flowers. They are bush hogging the area again, but waiting for us to save what we can.
