Note: The last species will grow best in a wetter habitat, a location with more soil moisture such as the ditch bottom. The 3 species labeled as having small seeds won’t grow if they get buried. One way to plant them would be to mix the seed in a bucket of sand and scatter it by hand on the soil surface towards the bottom of the ditch.
