Overflowing with bright blossoms, these chubby-cheeked planters are sure to elicit grins. The plants remain in their plastic containers inside the pumpkins, so no repotting is required. Cut a hole in the pumpkins' tops, and scoop out the flesh. Using a hole cutter or a drill, cut openings in the bottom for drainage. Fill pumpkins with potted flowers, such as chrysanthemums, and display in a sunny spot.
