This is a rose from the yard that I liked. No label. Last fall, I cut three mature sticks and pushed them into the soil in a garden container. Two didn't root, but this one did. They had no special care, other than watering. (The white flower is a seed- grown, dwarf dahlia).
It was easy to dig it out of the container - I removed some of the side pieces first. I could dig deeply from the side.
After removing the rose plant, I rinsed off the soil. I wanted to plant it in potting soil, with a uniform consistency.
Then I planted the little rose bush in a container. The tender growth wilted a little, so I sniped that part and placed the plant in the cooler garage for the day.
