Want unique, tough planters that don't look like everyone else's? Go to a brick supplier, get some clay chimney flue liners, and let the creativity flow.
They're generally less expensive than terra-cotta pots, ranging in price from $7 to $15. You can paint them, too. When you're ready to plant, fill the liners with gravel for drainage and that way, they won't crack when they freeze. Leave about eight inches open at the top to add potting soil. You can also set plastic pots on top of the flue liners. Later, you'll be able to bring the containers indoors.
