I think you'd be better off (more sure of success), with some sort of
tropical vine, often grown as annuals in cooler climates, that would take
off and grow several feet in one season. If it's a morning wedding, you
could grow morning glories, for instance. In 3 months, if the weather's
warm, they can grow 12 feet or more. You could also grow scarlet runner
beans - they will climb 8 feet or so after 3 months. Hyacinth bean and
asarina are other possibilities of this type which will grow 10-15 feet
under the right conditions. Mandevilla can be spectacular if it's warm
enough. On the other hand, if your climate is cool enough, you could even
grow sweet pea vines for this purpose.

u...
in three months there will be a wedding in my garden. i'd like to have a
floral arch of some sort, and someone has suggested a climbing rose, as it
grows fast and flowers all through summer/early autumn.

does anyone have any advice regarding this idea? i'd love to make a real
arch rather than a fake one, so i'm considering buying climbing roses now
and hoping they'll grow around an arch if i provide one!

am i dreaming, or is this a possibility?

thank you, garden people
