Fleshy leaves, long woody stems
I'd be grateful if you could help me identify this plant which I photographed hanging down from a balcony in London. It was at least two metres long, with bright green fleshy leaves and brownish woody long stems.
It was in a bright south-facing balcony, and I have also seen it on my holidays in Spain and Gibraltar. I would want to have it identified so I can buy one for myself:).
