Dennis, I wonder if your hippeastrum succumbed to something else? Or there were contributing factors besides cold. Mine have experienced light frost, a few degrees lower, and survived. Mine are all in pots as well. Shame, I don't like losing my hippies either. It's a crisp -27C (-16F) this morning, fortunately no wind.
