Paul, your Alfresco lured me into this thread.
Mine just finished it's 8th bloom for me and it was truly beautiful.
I got it along with some others as a gift in November; by Christmas week, it was head and shoulders above the others, until Rozetta and Candy Floss bloomed.
Here's Alfresco:
Candy Floss:
Here's Rozetta:
Behind Rozetta is Harlequin, also very lovely, white with a faint pink edge, like an outline.
I've had a couple of reds over the years, but this is the first time to have whites or pastels.
I think I am well and truly hooked.
Looking at yours and others on this forum, I know I am.
Beautiful plants.
