Iceberg
The Iceberg rose is a beautiful, bushy shrub with abundant white or near-white flowers. No fragrance or very slight fragrance. As far as we can tell from available sources, the Iceberg rose was either created by Kordes Roses or is a descendant of a Kordes Iceberg rose. Iceberg is sometimes listed as a shrub rose and sometimes as a floribunda. These different designations seem to refer to the same variety. In any case, the Iceberg rose is a wonderful landscape rose that can be grouped to create an impressive white border.
Iceberg also comes in climbing and tree varieties and can sometimes be found at big box home improvement stores.
