I can't not see this dude as being a centimeter tall

Looks like Rishi Sunak on a blade of grass.

I legit thought this was a shitpost, that's wild

Oh no, the tiny naked man is real? I thought he was made up, like the tooth fairy, mummies, and Dwaine "The Rock" Johnson.

I planted some of this in a suburban backyard in Houston.

In five years it rivaled the height of nearby trees.

A hard frost will kill the culms, but you'll get new ones sprouting up in the spring. They grow like crazy, we had one culm put on eight inches of height in one day. =D
