Inspired by Japanese Kokedama, these cone-shaped basket moss planters are very useful.

In nature, many forest and tropical plants achieve lush growth by climbing along tree trunks and attaching their roots to moss-covered bark. This helps recreate a similar environment, but in a hanging triangle planter, you can move around depending on the time of year. 

This one has an approximately 12-inch opening, the cone is about 15-inches long and the chain is 18 inches.
