Thanks, you two. It had a tag when I got it. I'm sure there's a squirrel conspiracy around here to steal tags. Or it might be down inside the pot somewhere. I potted it up into 'way too big a pot when I first got it, so it didn't bloom for 2 years, until January, and since then it has now bloomed 3 times! But it's been in the same pot for 3 years, too. Sadly, I will have to break the pot to get it out, I suppose.
It has a lot more red in this bloom than the last spike of blooms had. I wonder if it's the dull, rainy weather this week that did it.
