Stefano Boeri's Vertical Forest Under Construction in Milan

I was so surprised and delighted to see one of these proposals actually getting built.
This Bosco Verticale (Vertical Forest) by Stefano Boeri is currently being built in Milan.  I really hope this project works and we see those trees thrive, but those planters make me nervous - they just seem too small don't they?
