This is a guess but I have heard of this happening as a reaction to too much fertilizer and this can be a problem associated with miracle grow. I'll forward a few articles you might be interested in:

Otherwise, I really have no idea. I'll ask around and get back if I hear something that fits. Good luck.

Brittany,
How often are you watering?? Aztec Gold is a variety that seems to do better with more water. Are they in pots or in the ground? What is your fertilizing schedule like and what kind are you using? Also- is this a newly rooted cutting?

Newly rooted cutting... haven't fertilized yet... watering with water from my pond... watering about once a week... hmm... I haven't used miracle gro on it yet since it's only been rooted for a couple months (maybe)... could it also be due to young roots... it just can't support flower production yet?? Just a thought...
Brittany

Yeah Brittany you just answered your own question. It is very common that newly rooted cuttings simply cannot handle the energy needs to bloom properly. As the roots grow, it will. This may happen this season.

Good luck,
Tony

*sigh*... thanks... I was assuming that...

Jim Little's book suggests that too much water during rooting can cause flowers to drop before opening. One more thing to think about.

I even had some open... I thought that it may be a combination of sudden heat (I think we went from 94 to 110 within a week) and young roots... who knows... I atleast saw a couple flowers and one of them had 6 petals, so I thought that was cool...

Here is a wierd California Sally to check out Brittany. It only produced 10 such flowers and then was back to normal.

That's incredible... I had just gotten my Jim Little book and found something in there about anomalies... I mean, it was in the cards :)
