I found the shots of the yellow varigated one.

Looking good; I do not see any Black Knight in the photos but the first couple of pictures are the tall growing C. Intrigue (small peach blooms). I am guessing the green leaf orange is C. Orange Beauty. Of course you know the C. Tropicanna with the large orange bloom. The striped green leaf yellow flowering canna is best known as C. Striped Beauty. Not sure about the peach blooming green leaf, but "may" be C. Apricot Ice or C. Apricot Dream.

Thanks Kent,

I know, I couldn't find a pic I took of my black knight. It is finally really taking off so, I'll take pics in morning before the sun hits them. My Tropicana finally has a inflo on it also. I kept it in the pot too long, same with the black knight and they are behind the others that were already in the ground.

Just took some new shots this morning. And you'll notice the leaf roller damage on some but I almost have them under control. Hate those suckers, YUCK. I hand kill them every morning.

Pattie, I believe your green leaf yellow canna is commonly labeled in the U.S. as C. ÂRichard WallaceÂ. This is not the "valid" name. It was renamed here many years ago and has remained attached to this cultivar here. In your area, the leaf roller is a big problem, best of luck. Kent
