The easiest and most beautiful one I have experience with is " Red Cascade."
It' the first climber adapted for hanging baskets.
The cascades will reach several feet over the edge of the container.
The deep red--one inch flowers have a light fragrance & small leathery leaves.
It needs full sun all day and good circulation.
Canes can droop to the ground with flowers all the way down the stem.
Bloom repeat is fast...
Good in zones 5-11.
I think I'll plant one or two of these this year.
