I finally was able to assess all of my ice plants. Not a good winter for them. It would appear that three are for sure gone. With another two only having the slightest bit of life. But I'll leave them for quite a while to see what happens.
However, on two of them I noticed seed pods. I carefully cut most of them off. Then I went in the house and opened them up. Wow, it was not easy to get the seeds out. And they are TINY! Perhaps I should have let them dry totally out for a few days. Oh well. I still was able to get lots of seeds. No idea if they will be viable. But heck I'll try. Also they are from hybrids. So even if they are viable no idea what I will get.
