Definitly avoid the lotus. Someone planted them in a 380 acre lake near me, and now it is nearly unfishable. The plants can grow to depths of 16-18' and spread like wildfire. In the last 5 years the lotus have covered almost 60% of the lake.

I'll start treating my wife as good as my dog when she starts retrieving ducks.
