4 O'Clocks

We have some 4 O'Clocks flowering in the morning instead of at 4. This really shouldn't be a cause for concern but it would be really cool if I could get some flowers blooming like, and this isn't a pun.. ok it is, clockwork.
I know it's probably been done by plenty of people but I've never heard of or seen it done where a clock is made up of flowers that bloom in succession at the different hours. A real vegative biological clock. Ok maybe it would be a bocanical clock, whatever.
I remember my grandfather on my mom's side waiting until the wee hours for his night blooming flower to open. I really don't remember what it was except that it was a vine and it had a huge bloom on it. I was about 6 years old at the time so the hugeness could very well be relative to my size at the time. I can remember their cat seeming huge too. The claws on that thing were the most memorable since I got a closeup look at them one day after loosing a staring contest with it.
Well, clock or no clock they're still not flowering on "time".
