It'd be pretty funny if this was bred from Old Blush x White Pet, making it a fairly direct name translation.
Edit: To clarify, I made this comment because it was shown in a study to be more closely related to Noisettes than typical Chinas or Wichurana types. Specifically, Champney's, Blush, and Manetti noisette types. White Pet is half noisette and half Rosa sempervirens (as far as we understand), which could account for the unique foliage compared to wichurana-type polyanthas and the closer genetic testing to noisette roses.
Although the Old Blush part would more likely be off. It is more closely related to tea/chinas than chinas/red chinas.
The study is already in the references for Pink Pet (in commerce), so no need to dig too deep.
I just wanted to confirm that as a second year grafted plant it is probably 4.5' tall. It sent up huge basals in the spring, blooming later than others only to be eaten by deer. However, that did not deter it and it's COVERED in blooms once again. I'll be planting another two in this difficult bed at the foot of a hill with marginal sun ASAP! Also, I'm perplexed as to why noone smells any scent on this rose. While dead-heading I was wondering what had such a wonderful fresh fragrance when PP was the only thing in bloom. It turns out it was her!!!! The scent to my nose is strong clove. I wish I knew which group of roses is known for this; I've read it some where.
In the Columbus Park of Roses during a three-week drought that followed a harsh winter with continuing freeze-thaw late into the spring, Pink Pet was the healthiest rose in mid July, completely covered in blooms. I would change its size however, as it was easily five and a half to 6 feet tall and double in width. This is in zone 5 to 6 in Columbus, Ohio. I was shocked as I had planned to use my three as front of the border bushes.
Yes. It was definitely at least five and a half feet tall. I wish I had taken a picture but I don't actually live in Columbus, I was just there to see the garden. I'm unsure what to say for width as I did not try to peer through the thicket to see if it was more than one plant. However, they normally do not plant multiples. I cannot stress how huge healthy and floriferous this plant was amongst a sea of puny leafless bushes in their historical Rose section. It was just about the best looking Rose in the entire Garden of 1200 bushes.
