Eel grass success has variables: variety or species of Vallisneria used, location, amount of other competing species, how it is planted, type of winter it endures, if waterfowl or bottom rooting fish are present to uproot new plants and keep it from establishing. The native standard species Vallisneria americana (native) is the most durable, most tolerant, and tallest species of the genus. I no longer prefer it due to fairly fast spread and tall growth habit of up to 6ft tall. I prefer the shorter varieties although many of them are adapted to more warm winter water with a reduced amount of ice cover.
