Creeping plants or ideas for my raised water flower bed

[thisisallen]

Hello ,1st post, and not particularly knowledgeable with plants. But I've grown very fond of my pond, and recently I extended the pond and added this raised water flower bed.

My intention will be to fill it with plants (I still have a good filter, but I'm using lot of anoxic baskets in there to help filtration).

I was wondering if anyone would help me with a suggestion of something I could plant in the raised bed, that could eventually grow over the top, and perhaps fall over the sides of the waterfall/spillover.

Any suggestions welcome!

I like Parrots Feather and it likes to trail and is a very pretty plant.
