When I was spending a lot of time in Washington, DC about six years ago, they hadn't yet completed the World War II Memorial. Now they have. Click on images for larger versions.
I've never seen these before this year. If my notes from New York are correct, this is from Peru and is called Pachystachys lutea.
I strolled up the National Mall and made it to the gardens behind the Smithsonian Castle before it started to rain.
I'm here for another few months so I'm sure I will revisit many places such as the Air and Space museums and the National Zoo.
