This Plant is a Hardy Amaryllis, we in England grow them in a pot at Christmas time in our Homes. This one's a Hardy Amaryllis and I grow it in the Garden all year round, it stands 4feet high and the same across, it also produces lots of blooms.
What an amazing shot of this hardy plant. I only know the reddish ones in a pot. You really seem to have something of everything that is beautiful growing in your garden. Fav
