I have ferns that have "volunteered" all over my pond. When the roots get
into the water, the fish eat them. It's a real giggle to watch Big Red
with
a mouthful of root tugging for all she's worth to break it loose, then
swim
all over the pond defending her "prize".

I planted a few kinds of mint around the ugly edge of my VF. That stuff had
roots 4 feet long into the filter by mid summer. If you fill it with water,
they will come.
