This was a disappointment. The plants were growing alright and blooming profusely, although they looked a mess because they were getting eaten to smithereens by Japanese beetles. Then they suddenly all wilted (the entire plant at once) and died. Not sure if it was the plant's fault or mine or just bad luck. They did have nice white blooms for a brief period (only about 2 weeks), but I found the foliage weedy and raggedy looking, the large blooms out of proportion with the dwarf plant, and the white a glaring toothpaste color. All in all not something I would plant in my garden again.

Mont Blanc is a compact lavatera. The dark green leaves are a complimentary backdrop for the pure white hibiscus-like flowers. These bloom in late summer here in Seward, Alaska.
