Thank you everyone
...seems like I was just panicking for no reason. The bud that was the most yellow cracked open today!!!! YAY!!!!
But I still don't understand the yellow? Even in tarev's pics above. No matter what color the bud is it turns yellow-ish when it's ready to go? How weird!
Oh and one more thing, I gave it a 'shot' of fertilizer 2 days ago...do you think that action maybe pushed it over the edge to open up?
I am adding one more pic as a thank you present of my Slc. Little Hazel which opened a second flower yesterday. There are 4 more to come on the same stem.
