Here are a few pics, as promised, from our latest trip to the US Botanic Garden. My absolute favorite time to visit is in winter because as we discovered last year, it's maybe the warmest spot in DC. It really does feel like walking into a warm tropical jungle or a hot desert, depending on the room, which is like heaven when it's 20 degrees outside. Plus, it's so nice to see vibrant, blooming flowers in the dead of winter. It's like a little pick-me-up when you're tired of everything being brown and grey outside.
Anyway, if you are currently feeling winter blues, I highly recommend seeking out any type of conservatory or botanical garden in your area. You won't regret it. :)
