Seven months of rooftop outdoor growing: a big before-and-after comparison of succulents

I happened to have a few free days, so I tossed all these space-hogging big guys onto a friend's rooftop. First, to free up space for switching to other plants; second, I wanted to run an experiment and see exactly how Sedum would respond under completely hands-off, no-cover, no-shade, no-fertilizer, no-pesticide extensive outdoor growing conditions. (Thanks to yzjn911 for the material)

Let's start with the ones that have comparisons. The leaf cuttings of Olivia and Little Hibiscus have both grown a lot

Opu. Before I sent it over, it was still pretty plump

It seems it just picked up some color, but the stem has gotten much thicker

Silly Big Guy Dongyun. This one is interesting, I dug up photos from when I first bought it two years ago

Later, a photo of it wildly throwing flower spikes in the vegetable planting tub

How it looks now
