Gardeners' Notes:


On Jan 21, 2015, coriaceous from ROSLINDALE, MA wrote:

The Peggy Rockefeller Rose Garden at the New York Botanical Garden, where no fungicides are used, has rated this rose among its top performers.

Though the photos don't show this, the flower color is more accurately described as coral---a pink with orange tints.

This performs well as a shrub as well as a short climber. It is not a bush.

In Providence, RI, I find this rose is less generous with its rebloom than many recurrent roses.

Like most roses, this is adaptable to a wide range of soil pH, from 5.5 to 7.5.

"Seminole Wind" is the US trade name. "Rosarium Uetersen" (note spelling) is the German trade name. The cultivar name is 'KORtersen'.
