Nelumbo nucifera, The President lotus

4th day flower.

             Lotus are an invasive, or you might say successful aquatic plant. Don't plant them in an earthen bottom pond unless you want a pond full of lotus. I've had them in my pond rooted in 8' of water, and from that point the runners can spread another 15 feet on the surface, literally covering the surface of a large pond in 5 or 7 years. This can be depressing if you want to fish. However, you will not be sad at bloom time. A field of blooming lotus commands the attention of Kings. As glorious a sight as any mountain range they are. Yes Sir.

If you by some chance let them get away, the best thing to do first could possibly be nothing. Lotus are heavy feeders and if you've had an influx of fertilizer in your water for some reason, the lotus will eat every bit of it and possibly starve themselves out. When the nutrients are gone the lotus count will definitely dwindle.

This is what happened in my pond some years ago when I planted azaleas all around it and fertilized them regularly. The run off from the sprinkler system drained in the pond. As soon as the azaleas took root and started growing on there own, I quit fertilizing them and the lotus are now 99% gone. These first lotus were the native American lotus ( Nelumbo lutea ), nucifera species, and Mrs. Perry D Slocum, quite a sight in summer. I've never had The President before this year (Pond Mega-store $40 )... It's a bit more red than other reds and the species plant. It's in a 30 gallon tub now with 6'' of topsoil and water. The open flower is 11 inches wide.
