According to https://www.chambleeroses.com/order.php?id=143 , this miniature was bred by Ralph Moore in 1977. It went on clearance at https://www.antiqueroseemporium.com/roses/2211/rise-n-shine , Bob got it for me for my birthday (mid-June), I stuck it in the ground, and then I left town for a month. Here it is, six weeks later, a couple days ago, flanked by crabgrass.
After a month that contained about 29 days of rain, it should be defoliated by black spot. It is unscathed. It has not bloomed much yet, but things take time to be established. I’ll keep you posted.
