I really love this elegant plant! It puts on a beautiful show for months in my garden. The variegated leaves are attractive all summer and it has been in bloom since late August and still going in October, when hardly anything is in bloom here in zone 5. Everyone who sees it asks me the name, since it is a show stopper!
Weak growth and eventual death in very hot and humid climates. Ordered several from two different companies and none survived. Very weak plants. Have grown the regular obedient plant without problems for years. May be a great plant in different circumstances, but not in my very hot and humid climate in central MS.

I like this PLANT a lot...It does tend to lean over a bit (from being TOP HEAVY w/ Flowers) but I don't mind staking it with some 1/2" PVC......and with the leaves being green and white the PVC Blends in well. PLUS I go for almost anything Variegated & Late Flowering.
We all need more COLOR in our Gardens in late Summer / Early Fall and this PLANT Sure helps add color.
It's another "KEEPER" in my Garden
