Here's four green ones that I've let grow based solely on leaf-shape. The first one has a Kentucky-shaped leaf and the occasional yellow dot. No surprise, there's a real Kentucky eight feet away from it. The second one is a named variety called "Fiesta". It has a bit of yellow, a lot if you put it in the sun, but here it gets very little direct sunlight. Number three sprouted up underneath a huge mass of "Yellow Banana". There's a bit of yellow, but not much. Right below it are three more seedlings that have grown in the past year. Last shot is a very old one - almost 10 years - and I think the first seedling that popped in the garden. It's shaped like "Fred Sanders", which never holds much color either, but it's over five feet tall.
