Leo, Those are 2 good reasons. I've seen them poke up their heads, then wait for weeks after a snow storm to be seen again and be just fine. They were here on the property when we arrived 24 years ago and I have moved them everywhere ( in green or dried up bulbs forgotten in a container) , and shared 100s of them. Mine have now been in flower for a month. The bees and butterflies love them. They remind me of my childhood, picking a bunch with my Dad for my Mom. Shucks! Thats enough out of any bulb for me. jyl tuck yale bc
