One of our Christmas traditions is to go to the Seasons Greenings exhibit at the National Botanic Gardens. The exhibit features model trains winding their way around structures created from plant materials. Every year there is a different theme. We’ve seen round the world (very cool because it was lots of places we’d studied including Petra and the Pyramids) and a fairytale world. This year the theme was World’s Fair. Every year they also have on display iconic Washington DC buildings and monuments.
The cactus photo doesn’t really fit with the others, I know, but I just thought it was a wild and crazy plant.
And for those who are crafty and green-thumbed, a link to a cool DIY Christmas ornament idea that we got from a Botanic Gardens visit.
