8 is a nice number!! I heard the same about aloe vera flowers as well. One of mine looked like it was going to flower last year and it grew a long thin stalk, I was very excited. Then nothing happened 🙁

I have seen them bloom in South Florida once before, it sounds like yours was going to as well! Maybe it was just 90% there and needed a bit more, so hopefully this year you'll see a bloom or more!
