I don’t remember the name of this building.  However, these flowers are just between the Air and Space Museum and the unknown building.  The unknown building is between the Air and Space Museum and the “Castle” (Smithsonian Administration building).  All the flowers in this area are beautiful.  I hope to make it back when I have more than a few hours to spend exploring the National Mall.  I only took about 500 photos while I was there this time.  Definitely not enough to do this area justice.

If you look close enough, you can see the rain drops.
