Does anyone think it is likely that I can train a climbing hydrangea to grow on the ground around the circumference of my 12' round pool (circumference is ~37.5')? I am wondering if I can place stakes to train the path. Assuming I could, is there any reason that I would not want to do this?

Is growing one on a chain link fence a good idea?

Also, is growing a climbing hydrangea on a pergola (20'x10') a good idea? I thought I could grow it up one column, across the "roof" beams and down the other column.

Thanks!
