I bought a place this year that has a 1/4 - 1/3 ac pond that could be close to 30 yr old. It is stocked with a nice variety of fish, but is almost devoid of submerged vegetation. I planted a couople dozen gorilla grass (wild celery) plants in early Oct., but even if these live, I need much more of something. Several varieties of mud plantain look potentially usefull for the pond margin and not a threat to become invasive, but I've been unalbe to find other submerged plants that are easily managed, available, suitable for SW MO, and maybe even easily established. I wonder if there are any desirable pond plants that can be propagated from seed. I would welcome any suggestions about plants I should consider or sources I should try.
