Displaying your plants is half the battle.
I use a number of tricks to maximize space.
hang pots from a bracket on the window (helps that I have 150 year old windows)
I hang pots from my curtain rods:
I even put hooks in the window frame to hang pots from:
I also hang up to four 4 inch pots on a 6 inch pots and I also hang 4 inch pots on other 4 inch pots...3 deep to make a cascading effect.
How do you display your houseplants?
