Comments: Native Perennial Cherokee Co. At the first hard freeze, even though the plant has gone to seed and looks dead, the roots are still active. The sap freezes, splits open the stem and forms these "frost-flowers."

Very interesting and quite unique.

Is this plant growing in your yard? I am fascinated by it.

Tell us more about it, How tall? How big are the flowers?

I like unique plants have never seen or heard about this plant.

I like the last picture especially Amid, it looks so delicate, like thin satin ribbons. It's hard to believe it's frozen. Very interesting, thank you!! :D :D
