mandavilla vine

Hello, I'm a first time user and have a question about the mandavilla vine, I have had much luck with it on a trellis but would like to plant it in a flower box and have it hang over the box and down. Has anyone done this and will it look ok ? Thanks for any advise you can give.

 

Mandevilla is a climber... and needs support.... good luck if you try the cascade planter box.

 

Thanks I will need it !
