Annual Impatiens as Pond Plants

I have really enjoyed the blooming impatiens in the pond. I purchase several very sick looking clearance priced annual impatiens late this summer and simply rinsed the dirt off of the roots and placed them directly into the pond and tucked them next to rocks to hold them in place. They quickly perked up and are now blooming like crazy. I will do this again next year- what an easy way to add color to the pond.
