My observations mirror those expressed by others. In this warm climate this bush will get very big with very long canes.
The flowers are huge and well filled with a warm soft pink. They are so big, in fact, that the canes tend to bend over if not restrained in some way - especially in the rain. Fragrance is very good - on a good day the fragrance will reach out and grab you in the garden. Foliage is pleasing. New growth is red maturing to a mid-dark green and generally in scale with the size of the flowers - though a little more size in the leaf might be desired for athetics.
The soil and water are definitely on the alkaline side - but it does not seem to bother this rose. Nor has it been seriouisly bothered by pests or fungus.
When bent over, the plant tends to break well along the cane. In areas where it gets so tall, it might be a good candidate to grow and train on a fence. The canes are probably not lax enough for pegging, but I'm thinking if you can get the canes trained down enough to have a good horizontal run it would be an impressive display.
This has only been the first year for this plant. It is a budded on multiflora - which often is not a good fit in my garden - but it has worked well for this plant. With so many petals, not sure I will have any pollen to work with, and it may not set hips either. I certainly hope there will be something to work with as there are so many good qualities you would want to work into a breeding program.
Gardening in central Texas, USA.
Another year down the road, and this is still a very robust grower. It's decided affinity for putting out long canes (well over my 6 foot frame) makes it a little lanky underneath. As mine is planted in a high bed, it is a definte case of great plant wrong place. The flowers would be best appreciated from the roof of my house!. I should also mention that this one can be seriously affected by chili thrips. If it stays cool enought to get the horticultural oils out it keeps them under control (just), but something to keep an eye on if they are a problem in your area.

I live in a hotter climate - Gujarat state of India and have similar observation. This rose gets the thrips very much. Grafted on multiflora. Probably the most thrips affected plant in the garden.

In zone 5, 'Savanna' has been a disappointment. Small, puny bush and scant blooms. I think she will be coming out this spring. I suspect she prefers warmer temps and possibly a looser soil.

Zone 4a, Wyoming. Sticky clay soil with a west facing garden.
I got Savannah two years ago from the Walmart clearance rack looking pretty much on death's door. It came back from the brink with a few blooms in a lovely color, but smothered in powdery mildew (it was the only rose in my garden with mildew even though it has a prime location and is less crowded than most roses in my garden). I wasn't thrilled.
It died back to the ground over the winter and I was sure it hadn't made it. But a while after the rest of the garden woke up, Savannah started to grow, and has reached a beautiful five feet tall with a steady supply of blooms all summer, not a ton at a time but never without blooms. The mildew hasn't made an appearance and the bush is a nice tidy shape, full, not gangly. So Savannah gets to stay in my garden and I don't really care if it dies back that much if it can recover the way it does. The blooms also last a long time in the vase, making Savannah a good option for gift bouquets.

First year with Savannah and I'm very impressed. Zone 8, no spray garden in Washington State with a drought. Overhead watering only, shaded in the morning and late afternoon, Huge, fragrant flowers and beautiful foliage. over 4' tall year one. Maybe the best foliage of the 300+ varieties in the garden.
