Found this on the property. One of these flowers has bloomed for over 24 hours. and its only about 40 F outside. The throat is white even if it looks green, had no choise but to take the pic against the light. Since I know a little of the property and who has lived here, this one have been selfseeding for over 15 years.
the leave are about 5 inch long and the flower 3 inch wide.
there is no chanse for me to dig it up because it grows in several 8ft tall snowberry bushes.
