Native to North America, the Pond Cypress is a monoecious plant (having stamens and pistils in separate flowers on the same plant) with a blooming period of three months and grows inflorescence round.  The Pond Cypress favors sunshine, warmth and humidity, nevertheless it is highly adaptive even to cold, arid and waterlogged conditions.  It is therefore suitable to grow in swamps.  Its base is surrounded by cypress knees, which are roots that emerge from water and ground.  The timber is highly rot resistant, and thus a good material for shipbuilding and bridges.
