A little further back in time, flowering plants grow:
After the pioneer species stabilize the sand, flowering plants establish themselves. These aren't dune builders themselves, but with little bluestem grass, sand cherries, and hop trees, these yellow puccoons can help to hold the dune together once the soil is suitable, forming the second stage of succession on the sand dune. Dead plants also add nutrients to the soil. Several endangered species, including the pitcher's thistle, like to grow on the dunes as well. A few marram grass rhizomes are exposed here.
