I ditto what Polly said. I know several people who grow glads. I had a cousin who was president of the Utah Glad Society. He grew 1000's to sell. He grew 100's of varieties. They returned if it was a mild winter and he didn't dig. Some years if a person fails to dig their glads they will come back the next year. Other harder winters they will not. I have another cousin who orders expensive bulbs form a small hybridizer...new hybrids. He told me the other day that some years if he fails to dig them they come back, some not. "Hardy Glads" have smaller simpler flowers. Just my opinion....
