I've been wanting a butzii cluster for a while now, but they're surprisingly hard to find. The first time I ordered one, they canceled on me due to lack of stock. Then I found a really big one with probably over 100 plants in it, but it was very expensive. I kinda wish I ordered it now, but at the time I was nervous about spending nearly $100 on just one cluster. Thankfully, I finally found one just before our trip, at a very reasonable price. I sent the seller a message asking them to hold off on shipping so it wouldn't arrive while we were gone, and they told me it was a good thing I ordered when I did, because I got their last one. It's here now, and I really like it.
Often when you buy a cluster, it comes with a wire attached for easy hanging. I have an ionantha cluster which came with a wire, but I'm not convinced it's a true cluster. I think they took several similarly-sized plants, held them together by the roots, and used the wire to create the appearance of a cluster. And that's fine. The new one's a true cluster, which I can tell because there's no wire. I was able to hang it up just by clipping some root to the shelf.
My friend Jayme gave me these awesome magnets when we saw him in Portland.
I've got my eye out for more clusters now. But I probably won't get any that are really expensive right away now that I've decided to do a monthly tattoo appointment. Of course that's what I say now, and it's subject to change.
