Very pretty - no wonder you're asking. The common name I easily remember is Ganges Primrose; botanical name is asystasia gangetica.

There is also another variegated form, but the leaves are smooth rather than quilted. I've had both, but as potted plants on the lanai; having read that they were "invasive" I didn't want to plant them in the garden.

Merci beaucoup!
