In the fall of 2020 a dozen volunteers sowed nearly two acres of parking lot margins at the University of Nebraska Medical Center in Omaha. We used over 50 species and broadcast some 200 seed per foot. Why so much per foot? Because most of the areas where killed lawn and / or on slopes. Erosion control blanket was placed over most of the two acres, and this spring we sowed in more grass and annuals.
It was very dry in May and most of June, so seed germination is not what it could have been. However, those seeds are still there in teh soil and 2022 isn't that far away. We'll do more seeding next spring where some areas are struggling, but in areas where density is good (see below), we should be ok as much is coming up in the cool shadow of both weeds and annual / biennial / perennial flowers. In time the composition will change, but right now -- today -- the mid-summer flush is on. Soon, many of the annuals and biennials will die and set seed, and next year more and more perennials will take over the flower show. Prairie up.
