If your dining room isn't lacking for light, why not take this tip from the pages of Skona Hem and replace a chandelier with a hanging plant?
To get the look, use a Victorian plant stand, or search for a round hanging pot rack that can be augmented with hanging pots. Try using these Ikea Asker pots ($6) for your hanging plants. You can simply hook them on the pot rack hooks, and let them drape at an angle. I'd try using vining plants like heartleaf philodendron or swiss cheese plant, though ivy would also look lovely as well.
Have you tried using plants as a centerpiece in a room?
