My rating would be between neutral and negative. For me it's a painfully slow grower and shy bloomer, producing only an occasional bloom in the summer when it's outside and none in the winter. It also seems more prone to whiteflies than some other hibiscus I grow. I only keep it because, admittedly, the occasional flower is spectacular.

Although I found this plant to be a slow to medium grower, the beauty of the bloom makes up for it's slow habit.. Here in zone 5b, it must be wintered over inside.
