It is still too early to do now, but will go one year and ready for the water several times a day during the summer.

Is it sunny?

Plants that could be hung above:
Sweet potato vine (ornamental)
Vinca Vine
Petunias
Bacopa
Moss Rose (Portulaca)
behind Verbena

where in the shadows:
Ivy
Impatiens
the new vinca vine


I think it would be a pot deep enough to plant perennials.
