My Euphorbia infausta has had buds for at least a couple of months now (seriously). I'm waiting ever so patiently for them to open...and it looks like they will in succession. I watered my succulents yesterday and meant to pop back in to check on them about 15 minutes later to make sure none were standing in water. I forgot. This one had a wee bit of water in the saucer when I finally remembered. Here's hoping I don't find it deflated in a few days.
Update 07/23/11: Now that they are bigger, I'm kinda thinking that they are bud-shaped arms. I was looking forward to blooms...ah well, at least it's a happy plant.
