Hemerocallis 'Thelma Perry'



Add to wishlist Remove from wishlist
Antique hybrid nearly lost to cultivation but thanks to Jim Fox, we can keep this going. Jim visited Graham Stuart Thomas at his home in England and Graham handed Jim his spade and insisted he dig a piece. As if God himself spoke, Jim obeyed. This is the kind of provenance that makes the Keno brothers animated on Antiques Roadshow. Narrow elegant yellow flowers and fragrant in the evening, this is such a nice change from the huge modern hybrids as it retains a nice species look which we gravitate towards. It is important to keep these heirloom plants going as many of Perry's introduction are now lost to cultivation. Hybridized by Amos Perry who was one of England's first two Daylily breeders and he registered 'Thelma Perry' in 1925 as a hybrid with H. thunbergii as the pod parent and H. citrina as the pollen parent.
