I took this picture of a 18″ tall red flowering plant with thick stalk but thin cluster of red flowers. There were around 9 stalks on this hillside next to his house in Chester South Carolina. Really beautiful.
this is a beautiful introduced plant called Lycoris radiata, sometimes called Surprise lily, that flowers when the plant has no leaves. It is closely related to the Amaryllis.

I hope this helps!
