First time posting, please forgive the clumsy format.
I have Sandia Isa, Cameo and Pam Howden growing this year.
Sandia Isa is a small plant relative to its neighbors, but it has produced lots of flowers so far on usable stems. SI is the short plant front right in the photo above. To its left is Cherubino, behind is Darin's Moon and Allie White.
Flowers are beautiful, almost ethereal.
Cameo is also a short plant, also producing many flowers but on much shorter stems (I didn't pinch the plant when it was young). Flowers seem to have more texture than Sandia Isa, and are a pale yellow. Cameo on left, Sandia Isa on right.
Pam Howden (purchased from Old House Dahlias), seems to be healthy. Started producing early and keeps on pumping out flowers with a very nice form. Not crazy about the colors though.
