Questions on Zephirine Droughin climbing roses:

• Can they thrive in the shade?

• If I place in the corner of a home, what is the best way to espalier them to create the appearance they are climbing a column? I do not want them to touch the side of the home. I could plant a post in the ground and let them climb that, or maybe I could plant four heavy-duty plastic pipes in the ground, building a larger circle pattern from those, and let the rose climb that. What will give the best aesthetic result?

• What is the largest size that is available mail-order to Northern California?

• In the photo below, what is the white rose that is being mixed with the pink Zephirine Droughin?
