Looking for the Madison Rose, my granddaughter Madison passed away November 18, 2022. Yes, her name was Madison. I want to plant the rose in my small garden, I am in Zone 6b. If anyone knows where I can purchase ,please let me know, as far as I know this is the only flower named Madison that will survive in Zone 6b. Thank you

I'm so sorry to hear of your loss.

According to this website:
https://www.helpmefind.com/ros...
It was introduced in 1986 but then re-introduced in 1996 as 'Bayernland Cover' (and a couple other names).

Here it is in our DataBase with Bayernland Cover as one of four cultivar names:
Rose (Rosa 'Madison')
Maybe you will have better luck with one of the other names?
