Thanks for your reply. I had already purchased a Glamis Castle when I posted the question about it. I have it in a pot also. So far it is doing ok, but it's not summer yet! I have several other austins also in pots. They are slow to bloom and do get leggy. I am trying to figure out if I want to take out more lawn for them or keep them on the patio in the pots.
Would like to know if there others that are having good results with roses in large pots. Thanks!

Great Century provides absolutely HUGE, exhibition quality flowers. Only have one, and it is a tad stingy with the blooms. Minimal fragrance (like its parent, Queen Elizabeth). Average to below average pest and blackspot problems. It's about 3' high 4ft wide. It's a keeper.

Heirloom is a very reliable bloomer, with a nice sweet fragrance. Blooms last usually 2-3 days in the garden or cut. A bit more susceptible to blackspot than average, no real pest problems. Have three planted by the water. They are about 4' tall.

If you are interested in another lavendar rose--I highly recommend Lagerfeld. Silvery lavendar, it is a long stem blooming machine with Knock Out fragrance. On Fortuniana stock, it towers (without staking) at 8', and about 3½' wide. It will show occasional blackspot, but is so prolific that just pulling off the affected leaves keeps it in check. Lagerfeld photo taken this morning.

Same here in South Florida. One day only for the stunning porcelain blooms, then kiss them goodbye.
