corner gallery wall - without the specially made corner frames. Would need to be on a corner that is in an open area; this would be really overbearing in a tight hallway. But in the right space it could look amazing. Very art gallery.
Bamboo - dramatic specimen plant when grown in a large container (where it can't spread). It makes a perfect, fast-growing screen. 20 feet or more. Full sun and moist, but well-drained soil. Grows well in a container.
