This is so cool. I’ve had this Astrophytum coahuilense for 5 years and even though I got it with what looked like a flower bud, it never bloomed for me. My cacti have all been asked to bloom during bank holidays and weekends so I’m home to see it and they usually listen to me.
Astrophytum coahuilense looks almost like an Astrophytum myriostigma, but the “fur” grows closer together and it feels fluffier. It has no spines on its furry body, but the flower bud is both fluffy and spiny. It also grows super slowly. In the 5 years I’ve had it, it has only grown a couple of cm taller. Maybe because the little hairs block most of the sunlight.
Now what I’m trying to do is cross pollinate my Astrophytum coahuilense with my A. ornatum. I have no idea if it will work, but it’s a fun experiment. I found a cotton bud and mixed the pollen from the two flowers, making sure to hit the stigma in the process. I’ll make sure to update you if it worked.
