Some of the wildflowers need special treatment before they can reproduce. This is not the desired form of 'special treatment' for people, but some seeds germinate only if they first endure a few months outside in the cold. I sowed several seeds in these small containers, hoping they germinate in early Spring. One benefit is that I know where they are, rather than hiding among the many other wildflower seedlings. When they sprout I can nurture them until it is time to move them to a permanent spot.
