Bengal Clock Vine
This plant is in the same family as Miconia, and is also considered invasive, however it does not cause near the amount of destruction as Miconia. It is visually different from Miconia by having much smaller, solid colored leaves, and only growing up to 3′ tall, as a sprawling shrub. Clidemia also differs by the tiny hairs on the leaves.
