A couple of weeks ago, Dr. Richard Sutton, professor of agronomy and horticulture at University of Nebraska-Lincoln, sent us an email to see if we'd like to try out a few different prairie plants on the green roof. It's part of a larger research project (see their website here) trailing three species' survivability and persistence through dry periods, cold, and varying "soil" depths.

About a month ago I planted 29 Castilleja seedlings, 19 of which are Castilleja sessiliflora and 10 are Castilleja integra. Each Paintbrush was paired with one of three different host plants: Fringed sage (Artemisia frigida), Firecracker Penstemon (Penstemon eatonii), and Rocky Mountain Penstemon (P. strictus).

As you may know, a number of the plants on the Berry Prairie were grown from seed, specifically for use on the green roof. Starting wildflowers from seed can be as easy as throwing them on the soil. More often, however, it takes careful and strategic processes that range from refrigeration to scratching to freezing to burning. The post below gives an overview of the many ways we germinate seeds, including as it relates to Jenna's Indian Paintbrush project.
