they just look like seed. i don’t know that they are. little black things. around the horned stuff.
Maybe what I’ve seen isn’t what you’re trying to direct me to. The things I see just look like tiny, flaky black bits of ‘debris’ from the spines, from the cutting (?)
I’ll have to look closer the next time I cut one. I don’t live where it could grow, but I might get one to sprout over the summer.
