Growing along the corridor

What shall i do with the corridor space, and we have so much of them. Look left, look right :)

Besides the morning glory pot on the right, climbing its way up and subsequently to twill around the railings, creating a romantic entrance without the arch in future... ... what else can i grow out there?

The left corridor is mostly shady, catching some short hours of afternoon sun.

The right corridor is sunny, and rising with the sun.
