standing water and deep roots

I live in South Florida and close to the beach area. I have a gradual flood plain that goes from 9 foot above sea-level to 1 foot above sea-level. The water is brackish underneath, because it has salt intrusion. I have grown hybrid teas for a long time, but when Hurricane Sandy came by we had salt intrusion up to the 5 foot level. This happened under Hurricane Andrew well, but the water stayed for only an after noon. Under Sandy it stayed for several days. Under Andrew I did not lose any of my plants, though it wash touch and go for awhile. Under Sandy I lost several.

I know that when the water comes up into my yard, their won't be much I can do about loosing plants. However, I plan on taking this opportunity of replacing plants with some of the old fashion antique roses, such as Heritage, Quietness, Sharifa Asma, Caldwell Pink, Cecile Brunner, and Duchesse de Brabant.

My main question is how deep do the roots on these larger rose go. I Only have standing water far between major hurricanes. But I am concerned about the water plain. I had all of my hybrids all the way down to about the two foot above sea-level, but those plants were a lot smaller than the OGR I hope to grow.

I can not have a raised bed, it is against city code, so I just need to know how long the roots are..... Thank you for your input. It is greatly appreciated.

Heritage, Quietness, and Sharifa Asma are lovely roses, but they are not "antiques." (More like "reproductions. -G-).

Some nurseries sell Austin roses on their own roots, but many sell them budded to rootstock -- just like any Hybrid Tea or Floribunda. The roots for budded Austin roses, then, will be the same as your HTs, because it is probably the same rootstock.

As to the real "antiques" -- the Old Garden Roses -- they are all different types of roses -- Chinas (which love Florida), Teas, Polyanthas, etc. These are most-commonly grown on their own roots.

You will have to ask this question of the nurseries from which you order, and it will probably be different for each sort of own-root rose.

c. 2004 we had flooding in a public garden where I was working on an Old Rose restoration project. a stream had diverted itself to cover an entire rosebed that was c. 40 feet long and 3 feet wide. For more than a month the rosebushes in that bed were standing in 3 to 4 inches of water.
What surprised me was how many roses survived and thrived.
Devoniensis' drowned and died, no surprise there, but
Two large plants of R. moschata and all the Noisettes in that bed, there were a few Blush Noisette' plants and a very large and beautiful 'St. Leonards' and several unlabeled pink bush Noisettes of which all retained all their leaves and bloomed normally that year, no sign of damage but a small amount of die-back on the cane tips.

The fact that these were large plants with large root systems may have contributed to their survival.

It wasn't brackish water, but I was surprised that any of the roses lived.

Lux.

May be you should try Peggy Martin rose.

Would any species or near species be satisfying? I've seen these tough (but beautiful) characters survive in abominable conditions. I'd hesitate to recommend the best for your climate since I've never lived anywhere in the vicinity, but local nurseries and FL forum members might be able to suggest a few good roses. Species are definitely antiques! Carol

For roses on their own roots, each variety has a different root structure, some shallow, some deep. For roses grafted on Fortuniana rootstock, as Florida-grown roses usually are, roots are shallow, reportedly no deeper than 16". But if you are gardening on a sand dune, they might go deeper.
