A wall of bleeding hearts

Weeks ago, I reorganised the balcony and said that I was building a wall of bleeding hearts to keep out some of the traffic and get some privacy from (imaginary) prying neighbours. I am happy to share its growth thus far:

This plant definitely enjoys full-on sunlight. You can just see it straining to get more. I'm just really glad it's growing out and can't wait to see the wall complete!
