There are lots of balconies in Barcelona--there doesn't seem to be a lot of central A/C or dryers, so folks need their homes to be breezeways and need somewhere to hang their clothes to dry. A side benefit of balconies? A place to keep plants! Many folks have only Epiprenmum aureum, various Ficus or Dracaena, and the like, but this balcony had a stunning drape of Sedum morganianum and a crazy Agave--or maybe Aloe?
Here's a closeup.
I saw this Saintpaulia on a bench in the artists' district of Barri Gotic.
On the balcony below the apartment we're staying in was this large-leafed Cyclamen, I think. This photo is cropped and zoomed in--I might have to try a shot with my real camera!
