I love your bush, so gorgeous !! Is your Gruss an Coberg OWN-ROOT or Grafted-on-Dr.Huey? What's the best soil for it (clay, loamy, or sandy)? Does it need rain water to bloom well? Also can it take partial shade or full-sun is needed? How do you like the scent? I lost $$$ on roses dying through my zone 5a winter, so I always check for the vigor of own-root, before buying. THANK YOU. G. an C. is hardy for zone 5b.

This plant is own-root. The soil here is gravelly clay-loam that tests neutral but some areas of the backyard show alkaline salt-blooms in low-rain years. I think this is a variety that is likely to do best in full sun (what it gets here) and it is irrigated weekly (slow, deep watering) during the summer dry months. The scent is very good, like narcissus and one of the reasons I bought it. It is susceptible to whatever our variety of black spot is, but conditions that allow that only occur for a few weeks in early spring in some years, so not a deal-breaker here. Otherwise, extremely healthy and, yes, strong on its own roots.

Thank you for your reply. Your clay-loam is the best, I admire your garden-pictures, love those big rose bushes !! I'm making a "wafting fragrant garden" bed, and I'm waiting for Burlington nursery on the availability of OWN-ROOT Gruss an Coberg.
