The list below are plants that have all been found growing and thriving in the wild of the most coldest gardening regions. Many have hybrids that have been bred from them...these hybrids generally will be able to also grow in the same plant zones and survive the same long and bitter winters. Please do research them if you're unsure of their hardiness in your particular zone or region, and as always, with any seeds that you're unsure can be Winter Sown in your region save some seeds to start indoors.

Peren, sorry to mislead you... I probably looked at all of the same pictures you saw. I doubt if the temperature change would really cause that strange of a flower. i haven’t been able to find anything else similar. Might it be planted non-native? At least I found a new genus for me: pyxidanthera is terribly cute.
