This stoop looks so happy with the potted flowers blooming. I suppose I could do this on my stoop as well. My former downstairs neighbors had a potted plant on the stoop for a while (despite the lease stating that was a no-no), and it was quite pleasant. Then the plant died, and then they moved away. I don't think it was related.
Maybe I'll invest in some happy potted flowers. I'll start taking bets as to how long it will take for my toddler to destroy them.
