I've been really surprised by this roof. I expected sedums to be green and quite boring, but the various sedum varieties have been blinding us with colour for over a month.
There's such a wide variety in their basic form, even when they're just green, but this really comes out when they flower. The yellow star-shaped flowers are just starting to fade, but the clustered pink flowers on their red stalks are taking over.
If you look at a Google Earth view of this area, it's one of the least green parts of London. Hence, it's quite poor in biodiversity. So I'm really happy to see the green roof crawling with bumblebees like this guy...
Finally, here's a close-up showing some of the colours and textures of the different sedum varieties.
