I just purchased six 6-7 foot bald cypress trees from a nursery website, they should arrive in about a week. I'll post pictures, if anyone is interested. Although the taller young trees were more expensive, the benefits of being able to plant them at any time and any location (including a shallow area of the pond) without having to worry so much about frequent care... justified the purchase. I really do hope to get some knees, Rainman. I'll bet they would (eventually) make great habitat for fish.

Also, willows have been completely removed from consideration. Apparently the droppings can be toxic in the water and adult trees drink 50 gallons of water a day!
