If you're near Princeton, do you have winters that aren't that cold or
winters like this one? My family in PA got 70 inches of snow this year,
9 inches last year.

There is a poster here who grows roses in pots in Zone 5, and he moves
them near the foundation for a bit of winter protection. I also don't
know just how winter hardy Fourth of July is. Maybe he will respond
about pot size as well

I live in a townhome & am ristricted in my gardening efforts. My
anniversary falls on the 4th of July & so I would like to grow it. I am
willing to have a huge pot on my patio, if its worth the effort.

Nice idea. How huge a pot, Venu? This is a rose that *can* be grown
upright , which might suit a pot, but it's genetics want it to produce
10 - 14 foot canes. - which grow in 3 dimensions. I'm just guessing it
would like about 1 cubic yard of soil to grow in, in optimal
conditions.

My limited experience growing large roses in pots is that they don't
perform to their potential, usually flowering less than they are
capable of, and being more sensitive to fluctuations in watering. I've
never seen a pot big enough for the largest roses.

If you don't have any piece of ground that you could cultivate for this
rose, you can try it in a pot to see if it performs well enough to
satisfy you. If you have really extreme winter conditions some time,
you might need to take heroic measures to keep the roots from freezing.
