Here are two of the puddleduck’s favorites in a mix at a special price. They are similar as they both have hard seeds that can be submerged but they last into the winter without sprouting or rotting. When flooded, the ducks will forage through the wet straw to find the seed that has shattered from the seed head. This mix is easy to grow and produces a ton of seed. The ducks will always leave plenty of seed so it will volunteer year after year.
