Bald Cypress Knees Jigsaw Puzzle

Part brainteaser, part assemble-it-yourself art, this challenging, nature-themed puzzle is great for improving muscle memory.

The cypress knees on this Bald Cypress tree look like small mountains or rock formations. Like many things in nature, they are more than just a cosmetic feature -- it's been hypothesized that cypress knees aid with oxygenation of the roots and/or serve an anchoring purpose in swamps.
