Not even sure what to write!
Wendy Bedrosian (Wellesley Hills, MA) 9/2/2017 8:23 AM
These flowers were so big, I called them Dr. Suess flowers. The stems were like thick celery stalks (stem sounded too dainty). And the stems were very very long! Unfortunately, despite being staked, it still got too heavy and toppled. I used 5 stakes to try to keep it upright and it is still leaning and Inthink the stalked cracked because it is droopy. The three blooms I clipped were incredible, though.
HUGE flowers
Linda Abbott (Ogden, UT) 1/6/2016 1:02 PM
The writeup says 12" flowers. We had several that were actually 16" across. The only thing you can do when you see one like this is laugh. You just have no other way to express your surprise and delight. The color is beautiful, and that alone should make this one outstanding, but 16" across??? Wow. Order early. This one sells out fast.
Stalk & flower over 7 ft.

Amazing. U won't believe the pics. Where can I send.
One of my favorites
K. Hauswald (Woodland, WA) 12/30/2013 9:43 AM
The first flush of blooms on this were absolutely huge! A great producer in my garden, gorgeous color, and nice long, strong stems. I got so many compliments on these. The flower form is beautiful and held on to the color well, even through a higher than normal heat wave. Plant stalk was very sturdy. A keeper in my garden.
