Gardeners' Notes:

The ARS Encyclopedia (first American Edition, 2003) cites this rose as likely the most popular hybrid tea grown at the time of its introduction. The flowers are large, fully double, globular, nod a bit and are quite fragrant.

Bought Mdm. Carolyn Testout because it's reported to be tough as nails and is not agressive. Wanted something that didn't require much care and wouldn't overwhelm a small arbor. Ordered this plant two years ago, bare root, on its own rootstock from Vintage Gardens in Sebastopol. I'm extremely pleased with this rose.Blooms heavily in May and then repeats throughout the summer until fall. Nice fragrance.
