I've always wondered what was used in creating rose standards, so thanks for that explanation, Zuzu!
Maybe I'm doing something wrong with them, but I've never been able to winter one over. The last several years, I've left them potted and brought them into the garage for the winter. Are there any zone 5/6 people here who leave them outside, either in planters or in the ground?
The ones I see around town are always in planters.
