It might just be resolution of the photos, but the pink tone of those petals are fantastic!!
Much better than some of the typical dull pink petals I've seen!
Well, as the green leaves in the photos do not have any hint of a reddish hue...might it not simply just be due to the fact, that the colours of these petals are f...... fabolously fantastic? Said with slightly hidden envy - and pardon my french! And please, allow for my utter ignorance of matters photographic!
The broad, rounded tips of some of the petals will have to make me read up on the differences between appletonianum and bullenianum, when I get home from work, later tonight!
Lastly, do you have any info on the parentage of the depicted plants?
