Bill Warriner, a floribunda, was a Zary-Warriner collaborative effort. Helpmefind lists the introduction year as 1997, but a few years ago I ran into my 1995 invoice from J&P for this rose, so be sure to always take all of that HMF information with a grain of salt.
It was planted in full sun, but my neighbors subsequently let an ugly scrub oak seedlling grow into a big ugly scrub oak tree, so now it's pretty much in full shade. In spite of that, it blooms constantly and abundantly.
