I took a sidetrip and participated in a two-person plant rescue!
I have a good working relationship with some local developers. One in particular has a girlfriend who likes native plants. His girlfriend is sort of fru fru... she loves to be politically correct in social circles by being able to chat about using natives but her pretty finger nails prohibit her from actually digging them up or transplanting them. When I learned of her love for native plants, I offered to go over to one of his properties to see if there was anything she'd like. He gave me the address and I went over and e-mailed photos to them of what I found with identifications and where they would work best in their landscape. They asked me if there was anything I wanted over at the property. There were a few plants that interested me. They told me to please go and get the plants that I wanted and if it wouldn't be too much trouble... would I please dig up a few for the little woman. Of course that was fine. Later on they learned I was a member of a native plant society that has members who volunteer digging up plants to transplant on public lands. Some of this man's properties are so large that not only are there plenty of plants to dig up to transplant but there are plenty of plants for the volunteers to take home to use in their own landscapes. So there's the history on how I get advance notice from this particular developer. His girlfriend gives me a list of plants to look for and if they're there, I dig them up for her and in the process I can take as much as what I want from any area that won't be open space.
The property we went to today is slated to become single family residences, townhomes, condos, several playgrounds, outdoor activity areas with a central pool, and an "L" shaped strip mall. There will be no open space.
I don't normally find anything I am interested in at plant rescues but today I found two sedges that are of particular interest to me. One I can't identify but I've got a little voice that tells me it's desirable.
I also dug up some Osmorhiza claytoni (Sweet Cicely), and Thalictrum thalictroides (Rue Anemone) as well as a few misceallaneous.
