Margaret Furness, editor. “Ley’s Perpetual”
A rose of mystery: it was said to have been found by F. Ley in the U.K., before 1937, and introduced under this name by Sunningdale nursery in 1958. Other references say it is from before 1900, and was bred in Germany from Gloire de Dijon. The Vintage Gardens Book of Roses says it is a Tea-Noisette with much affinity to the Dijon group, with reliable re-bloom. Sweet Tea scent, described variously as moderate or outstanding.  At present only ‘Saumarez House’ and Ruston’s are recorded as growing it in Australia. Ross Roses have a stock plant, but no-one is listing it for sale.  Low-growing (with pruning) at Renmark, but said to reach 4.5m.  Cream in the bud, becoming light yellow. Blooms in flushes. Rounded leaves. Hooked prickles.

Still shrouded in mystery, little is known about the origin of this rose. Clearly a Tea-Noisette with much affinity to the Dijon group; flowers of strong Tea Scent, scrolled and very full, ivory cream in the bud, opening rich canary yellow.

LEY'S PERPETUAL. This rose was given to me by Mr. Wyatt, who for some time edited an excellent magazine called The Rose, which unfortunately ceased publication. A seedling from 'Gloire de Dijon', it has a great deal in common with that
