i have a plant that i can't identify. it has dark green folige with a very distinct purple running through out the leaf more pronounced on the underside. the leaves are saw-toothed but not sharp. the leaves are not thick, more like an outside plant than a house plant. the plant i got the leaf from was huge and the leaves were easily six to eight inches long at the base shoter as you went up the plant.i was told it was silver dine or tine but have not been able to find it under either name. can you help me identify this plant?
