Recently we donated plants including wetland rushes and sedges, herbaceous perennials, and many flowering bulbs to a greenroof project at Oregon State University through the Crop and Soil Science Department.  We assisted in the planting day, and have been back a few times to check on progress.  Our plants have been used in other greenroofs before.  To learn more about this project check out the local news’ link and video of the students building the structure.  Soon there will be a website dedicated to tracking the differences between the classic half of the roof versus the greenroof.  Once this is up and going we will have a new post with a link.
