Thank you Hegar. Those glochids..I still remember them after all these years ( about 40 in fact) nearly impossible to remove and left my fingers a bit swollen for several days. I bought several Opuntias and was careless handling them but I learned fast! Even so, it would be tempting to have some of those Opuntias in your post, if they didn’t got so big . My windowsills are pretty crowded already.hegar wrote: ↑Tue May 25, 2021 2:43 am Yes, Mrs. Green, some Opuntia spp. do have large and showy flowers. Those plants overall are also quite easy to cultivate. However, therein lies the problem. The prickly pear will outgrow most other cacti. It does not help its reputation, that in addition to spines, that group of cacti also does have glochids.
I do not see any reason, why the Echinocereus poselgery would not grow and flower on a windowsill. The problem with that cactus is its growth habit, i.e. forming long. thin stems, which tend to grow into every direction possible. So it would make sense, to reign those stems in and forcing them to grow more upright. I was thinking of using a tomato cage or some other structure to do just that.

Great, I am tempted to order an E.poselgery , despite its unruly growth. As you say, it should be possible to ‘cage’ it, in some way.
