What common garden plants can be used in an ornamental fish pond?

Question

I've discovered that Creeping Jenny and Peppermint do well in my pond. Aquatic plants (like Arum, water hyacinth, etc.) are so very expensive I'd like to find other "regular" plants that will do well grown in water. Any one had success with other common plants?

japanese iris in pots with just an inch of the soil out of the water.... watercress from the grocery store tucked in around the stones of the waterfall ... arrowhead plant from a creek nearby
