In this patch, I'm working towards a mix of violets (Viola sororia), nimblewill (Muhlenbergia schreberi), white avens (Geum canadense), and yellow woodsorrel (Oxalis stricta). There's also clover, chickweed, mock strawberry and others I'm weeding out. The shrub is an elderberry (Sambucus canadensis) which should get 10 feet wide. The top right corner is a mix of Philadelphia fleabane (Erigeron philadelphicus) and orange coneflower (Rudbeckia fulgida).
This is an urban area in the North American Eastern Temperate Forests. My yard is the lowest point of the street next to the storm drain, a "rain garden" for the block. Here, the violets thrive from deep shade to full sun. They are the host plant for fritillary butterflies.
Beautiful! Great work! Thanks for doing this and for sharing it with us here :)
