I have a couple cacti in bud right now, but this one is the closest to blooming. This is Echinopsis subdenudata, a first bloomer for me, and one of the flower buds is getting hugely tall! It's a night-blooming species, and I'm thinking that tonight or tomorrow may be the night.
Also of note today is my Hoya subcalva cutting that I got off eBay in July. It rooted within the first week after I stuck it in the pot (yay!) and then pretty much sat there looking exactly the same for two months.
But yesterday, I noticed that there is a new growth starting! Hurrah!
