Talk:Rosa 'Korschwill'

Notability question
@Jan Arvid Götesson, and anyone else who has an interest, I'm having trouble confirming the Notability of this cultivar. When I did a search in Google books I only found two short mentions of it. Do you have any other sources that would show that it is a particularly important or well known rose cultivar? 🌿 Mt B o t a n y (talk) 02:08, 25 February 2024 (UTC)


 * ADR - Allgemeine Deutsche Rosenneuheitenprüfung is set up by the Federal Government of Germany, the Association of German Nurseries, and test gardens.
 * The Federal Government of Germany says: “Value properties such as frost hardiness, flowering behavior and leaf health are tested over the course of 3 years without the use of pesticides. New roses that are resistant to disease based on testing and have a high decorative value receive the ADR quality mark. To date, over 2,000 varieties have been tested by ADR, of which over 200 varieties have been awarded the coveted ADR designation. The current ADR variety list now contains 192 varieties.” (Current list is a bit shorter according to ADR)
 * So KORschwill belongs to a select group of cultivars.
 * Peter E. Kukielski wrote in 2015: “‘Black Forest Rose’ has only been around for a few years but it has already established itself as one of the most disease-resistant roses, which is exceptional for a red rose.” The full page in Peter Kukielski’s book is more than a mention.
