I'd give the tall planter a go. I have several not too tall climbing roses in pots, but they are 50cms deep and 50cms in diameter. I have 2 in a trough, but it also is 50cms deep and 100cms long, 45cms wide. When I fill the pots I mix manure, compost and earth in the bottom half and top up with compost. They will need regular feeding with rose fertiliser and lots of watering.
Here is "The Pilgrim", a David Austin Rose, about 4 years old.
And Malvern Hills and Phyllis Bide, about 6 years old.
