Gene, I'm in zone 6 here in Pittsburgh, PA. Most people who never saw a tri-color is amazed at how beautiful it is looking thru the leaves towards the sun. Seems the light just makes the leaves sparkle. I collected about 20 seeds due to the squirrels getting there before me. I tried to eat one, taste bad. Like chewing on bark. I plan to try my luck growing them. I figure they got to freeze first before sprouting.
