Yes, Stan, more data is good.
I've noticed that although evergreen, my CVs enter a dormant period where no new foliage is growing. Or should I say, none that I've noticed. However, they look as lush and green as a fan producing new foliage.
Do you know approximately when that period starts and ends? When the new foliage starts to grow at the end of that period does the old foliage start to yellow and die?
The first sample evergreen appears to not be in that dormant period (I see smaller than mature size leaves in the centre of some of the fans) . On the other hand, the second sample evergreen seems to show that it was dormant at that time (all the leaves look mature size and there do not appear to be any short new leaves in the centre of the fans).
