Amazing Grace can be beautiful in warm, dry weather. Packed with petals and fantastic fragrance. However, in rainy, humid conditions, the blooms won't open. Foliage is beautiful. The plant I have is grafted onto fortuniana rootstock.

Mine are own-root and still struggle to open in humid conditions. They are wonderful if the weather conditions are just right and are always blooming though. I'm thinking of moving them to full sun (over 100 F common) instead of where they are with a few hours of shade break in the afternoon before getting sun again. It seems a shame to potentially fry the blooms but rotting unopened ones are a problem too! If I have time, they can be teased open if I catch them in time.

Excellent smell, size and petal count already on a small own root potted plant (that is less than a year old) from Heirloom. Has tripled its size rapidly; listed as a HT and Shrub in the Heirloom catalog.
Have high hopes for this one.

I love this rose but in my climate without high culture, and on it's own roots, it lacked as much vigor as I'd like and didn't repeat as well as some. I think it might be better budded but I never tried it to be sure.

I was gone for the month of May, but I fed it (magum rose food) right before I left, with orders to water heavily. That 100 degree May heat wave + the food and WATER must have kicked in. Amazing G sent up 3 canes, 3x bigger than the original mail order plant. The few flowers on the little plant before I left were huge and VERY fragrant. Pretty unusual to get good fragrance (& size) on a runt own root one gallon.
I am hoping its shrub category emerges. And supposedly thornless!!!!!
Fredric Mistral own root is bustin out all over it's own root 2 gallon pot as well . Do u have it. I assert that the French Romaticas perform in LA better than the Austins or the English Legends: Peter Mayle, Yves Piaget, Marco Polo and Caruso are all work horses with better cutting stems. I hear great things about FMistral as well.

I've heard good things about 'Frederic Mistral'. All in all my luck with Romanticas has been mixed but then it's been mixed period.

My roses make do with a third of the water they used to get and it makes a huge difference.

I'm sorry to say 'Amazing Grace' had thorns for me. If you get a smooth one I'd love to hear about it.

All seven of mine definitely have thorns also.

I have quite a few of these and so far, there have been plenty of blooms and very nice fragrance. But the blooms seem to shrivel in heat, don't always open in high humidity, and immediately shrivel up in the vase. Can anybody comment on whether this is just something that happens when they are new? Mine are all less than a year old, own-root, both in the pot and in sandy soil. Very vigorous otherwise.

Amazing Grace is a deep-cup bloom with many petals .. that means a HIGHER DEMAND for calcium and potassium. My Pink Peace as own-root fried in the heat & full-sun ... then I gave it sulfate of potash/gypsum AS SOLUBLE-FERTILIZER WEEKLY, and blooms no longer fry in the heat & last longer in the vase. Calcium makes petals solid. Potassium regulates water-osmotic pressure to force bud to open, and to move water UP the stem. Clay has more potassium & calcium than sand, thus it's easier to grow zillion-petals Austin roses in clay. There's a Texas A & M study that showed calcium helps plants to cope with heat.

Same with Wise Portia as own-root: blooms fried in the heat in partial shade !! It improved with Azomite (mostly calcium powder). Blooms had less petals as the bush aged, so I knew there's a depletion of calcium. I dug that up, put tons of gypsum (calcium sulfate) to break up my hard clay. This year, it gives TWICE more petals, very firm, and long-lasting in the vase. I also give it SOLUBLE sulfate of potash NPK 0-0-50 to balance out the calcium in the planting hole.

Thanks for much for the information! Do you think that since alfalfa is so high in calcium, the compost made from it should be sufficient?

Grass clippings at NPK 4-1-2 is cheaper and higher in nitrogen than alfalfa meal NPK 2-1-2. I planted 20 tomato plants this year, first year ever with grass clippings mixed in with soil. I'm very impressed: thicker stems, no wilting in hot sun (best ever in 2 decades of tomato crop).

But there's one plant that got pine-bark & sand in the planting hole, and it's wilting with tiny leaves .... too dry & low-nitrogen. University of CT documented the release of nitrogen of grass clipping is WITHIN A MONTH, so alfalfa is best as FRESH on top, rather that composted (nitrogen leaches out completely after 1 month).

The tomatoes with 1/2 fresh grass clippings mixed with 1/2 clay have the thickest stem & most fruits. That far surpass the year which I used 40 lbs. bag of alfalfa meal for my tomato (too many leaves & weak stems). However, I tested mixing fresh grass-clippings with bagged sand .. that didn't work for roses, thanks to the quick lime (pH 9) in the bagged sand, and perhaps roses can't handle the acidity of fresh grass-clippings like tomatoes. So I'll wait until 1 month for the grass-clippings to decompose, before planting my roses. Will let you know later.

Last year I TOPPED my 16 own-root roses (in pots) with alfalfa pellets .. that worked well. But this year I MIXED alfalfa pellets INTO potting soil for my 7 own-root roses received mid-May .. I did that 2 weeks before planting rose into the pots. THAT DIDN'T WORK WHATSOVER, The acidity of decayed organics stunt roots and leaves turned pale due to lack of oxygen. Alfalfa meal is quite dense & wet & sticky, so roots can't breathe. Organics is best on top, except for dry grass-clippings which worked great mix-into clay for tomatoes, but I'll wait 1 more month before planting roses into the ground with clay mixed with grass-clippings.

Excellent info, thank you so much!

I wish that they would list on the the bags of sand whether or not they have lime. I've had drastically different results with bagged sand after assuming that they were all the same-big mistake!

They also put nasty chemical quick lime in bagged-cow-manure to deodorize & kill weeds & but never list the ingredients !! William Morris, Darcy Bussell, and St. Cecilia all died thanks to bagged sand (with quick lime) mixed with my native clay, plus 5 other roses grafted-on-Dr.Huey. I spent 2 hours scraping off cow-manure since that stunt my tomatoes & and my roses turned pale with that chemical-quick-lime (pH over 9). Grass-clippings worked wonders to fluff-up compact clay, same with alfalfa-hay. I did mix alfalfa-hay (large strands) into clay one-month before planting, and Tchaikovsky broke out in 10 buds as 1st-year-own-root. LARGE chunky organics help to aerate clay for best root-growth. Alfalfa hay in planting hole works better than alfalfa meal since alfalfa-hay is less acidic & slower to decay.
