A really attractive way to display a selection of small pot plants.
Try fragrant plants such as french geraniums and pelargoniums, or herbs or lavenders.
Site the ladder near to a house wall to let the air be gently perfumed with the scent of these fragrant plants.
For a gorgeous display try using the blue and white Delft style plant pots with pink or red pelargoniums.
Alternatively try the ladder with a selection of little plants such as sempervivums in vintage terracotta plant pots.
