Too many plants? If your porch space is on the smaller side, a three-tier garden screen (consisting of pairs of copper K-style gutters) helps to keep plants out of foot traffic, freeing up floor space and providing a decorative display.
This is a cool idea for an outdoor patio, porch, or deck. You can roll them down for privacy or when the sun is shining right in. It would look great if they were all closed at night and there was seating and soft lighting. - gazebo too
