Rose rosette disease resistant roses
I removed 3 knock out roses with RRD 2 seasons ago and want to replant roses this year. I have two questions. 1 Is there any other cultivated rose beside Top Gun by Weeks that has shown resistance? 2. I grow Tansy (tanacetum vulgare) in the same bed. Is there any data that points to Tansy as a harbinger of RRD?
