I now think the "mystery plant" might be Schreiner's SWEET SERENADE (2011). It's listed in Joe's catalog, whereas SWEET SEDUCTION is not. SWEET SERENADE is very pretty and I think I might be able to identify it next spring if/when it blooms if that's what it is. Every year Joe gives me recent plants from other hybridizers as gifts in addition to his own plants, so I'm used to getting newer Schreiner and Keppel rhizomes from him.
