Picture from last year.
seems that if they get sunlight they do turn nice and red, fruit growing in shade only have a bit of hue, a few are green.
I have to say, I really liked this variety, productive, pretty and taste great at least in our climate owner was not around this year during expo for me to get access. or scion. this tree is in a private collection. I did plant a seed last year, that is growing very well, but do not believe its a poly.
