I recently came across this cute shop, Little Leaf, around 14th Street, DC. I loved the vibe of the whole shop and although the space was pretty small, I felt like I could stay there for a while. 

They, of course, had different plants you could take home, books about plants, small home decor, cards, and more. If you're ever around 14th Street and you're looking to buy new plants, you should definitely stop by this place. 

The store owners were warm and extremely knowledgable, so they'll be able to help you out if you have any questions about plants and will encourage you to browse and take photos.
