SDC was a semi dormant for me in Hobe Sound. She sure performed her petals off I can tell you that!
Becky, take a look at my photo of her in my Hobe Sound garden -- get a load of all those buds! Note the date the photo was taken and then go down & read my comments in the comment section for the plant. She increased like rip too!
Funny, but up here I've had some dl's that went dormant over winter which are listed as semi evergreen.
Just goes to show you things aren't always written in stone. There are always subtle differences to consider - microclimates being only one of them.
