can I pick your brains about Sports and Reversions?
I spent a wonderful afternoon with my sister and brother-in-law yesterday. They have a wonderful 8-year old multiple planting of White Sparrieshoops that sit slightly down the slope from their house and just outside a long expanse of window. These are all own root roses and nothing else has been planted where they are (in very deep and amended holes dug into a mountainside), but this year there are pink buds coming up on what look like suckers coming up near the base of two of them.
Upon coming home and doing a bit of research I see that White Sparrieshoop is a sport of Sparrieshoop. So, my question is, are these probably/possibly reversions to the original? My sister commented that the new opening blooms looked a lot like some Poulsen roses she had admired, and I also noted that Else Poulson is a parent of Sparrieshoop, so in my personal set of (very often totally wrong) assumptions, I am thinking what they are seeing are reversions, but....
What do you think?
