I live on the outer banks of North Carolina we have had a very cold and icy winter here. This plant I grew from seeds several years ago, this one has been outside in cold windy, icy, freezing weather. It started to bloom in early March and is still in bloom. It did not have any freeze or wind damage. I do not remember its name, it has survived a most awful winter, if any anyone can tell me what it is I would be grateful , it is white but also has had blue and pink colors on other plants.
