Cold = anything under 73. But for plants, when it starts going below 40 at night, it's time to bring them in. Been close, but hasn't happened yet. Yes, looks like buds are forming on many of the tips. Just took these pics of some of them. Cute little "I think I can" cutting: This one won't change colors (the foliage) but has some buds: This is really purple in person but look red in pics, I think you jinxed the pics, Toni! LOL J/K!: An example of how some just won't change foliage colors, I guess. They're in the same spot, in the same pot. Also more purple in person: This strange little cutting keeps making smaller and smaller leaves. It's the only one like it, many cuttings around in various places, though in the pic above, you can see the 'purple' plant just has smaller foliage. This cutting probably came from that plant, though I don't remember for sure by now.: Uploaded with ImageShack.com

Like most Cacti...it needs a cooler rest than you can find in most houses. Try about 50 degrees or even less. Dave Milwaukee

Thanks! Don, I must've been the one to change, because they were just the same. Especially the naïve one. We'd go to her parents house and the wife would say, John, cover up this part of the movie, obviously having watched it before we saw it. We were talking about all those who finally came out of the closet and she'd say, really? I didn't know. Except one. And she said, heck, even I knew he was! The one who we talked about the most... a once shy lady who has turned out to be one of the funniest and most outgoing women. HI-larious! We loved how confident she's become.
