Hi again..

I have 3 different kinds of rose bushes. Sorry, Oklahoma is the only
name i remember. I thought one was a Tropicana? Anyway, they started
out peach, dull pink, and red. Now they are about 6 shades. Thank
Goodness the bush retains it's original scent as they are all
different. And the color change doesn't annoy me, especially since i
have a brilliant deep pink one for the first time this week, but i am
just curious, is this the work of the bees and butterflies?
