In all my time doing Photo of the Day, I don't think I've ever seen a picture of the outside of the U.S. Botanic Gardens, like this one by mosley.brian. Usually a lovely reflective night shot like this is the Kennedy Center, but we've been happy to see quite a few of our photographers head towards the gardens once the weather turns cold. It's open all year long and a fantastic way to get your dose of warm, flower fragrant fresh air during winter. In fact, they have extended hours until 8 p.m. every Tuesday and Thursday in December (except Christmas) with free musical performances.

Here's your last reminder to join us for a DCist Flickr photographers meet-up at Rocket Bar, this Sunday at 2 p.m. Hope to see you there!
