The Gardeners' Chronicle and Agricultural Gazette, Volume 9, page 743 (Nov 24, 1849)

The history of the Manettii stock is as follows. Some 12 or 15 years since a Signor Crivelli, of Como, attracted by an article in Loudon’s “Gardeners' Magazine,” Wrote to me, offering to exchange some seedling Italian Roses for choice named varieties. I sent him a small collection, and in return received from him some seedling Roses; among them were Rosa indica grandiflora and Rosa indica Manettii, two very small plants. These he described as being hybrid China Roses, and most valuable Roses for stocks in the dry climate of Italy. I soon found that although so much alike in habit as scarcely to be distinguished, they differed most materially in this respect; the former could only be propagated by layers, while of the latter every cutting grew. I gradually increased my stock of the latter, and now propagate from 40,000 to 50,000 annually. As with all new articles in gardening, I had to buy some experience, for I found if I grew them in a rich soil and budded them at the usual period, the buds rotted; they appeared to be drowned in the superabundance of sap. At last I saw it was necessary to plant them in poor soils, and bud them in September.

I presume this stock has found favour in America, for last season I received an order from one house for 2000.

I am slightly confused; the description of this rose states, "thornless (or almost)", but some of the pictures and comments are of a very thorny rose.

I'm surprised to see that its bloom habit is described as "blooms in flushes throughout the season." We have several Manetti in the Sacramento Historic Rose Garden and all bloom only once.

I am surprised too. Although it has a rather long blooming period (and I am sure I have seen the odd bloom later), it basically is a once-flowerer. Thanks Anita.

I grow this rose and am surprised that it seems to have contributed nothing to the later race of Noisette roses. It is thornless, vigorous, and the flowers are just beautiful. For me, it has been very disease reistant in my organic garden with no spraying of even organic sprays. It grows very wide and low. It is currently 8-10 feet wide by no more than 2.5 feet high. The canes arch out, and being totally thornless in my garden, I've let it somewhat overgrow a path and I can walk right through the canes with ease. Does anyone have any thoughts on why this rose was never used for breeding and is it thought that the assumed parentage is indeed historically true. It might be fun to pollinate this one with some tea rose pollen and see what comes of it.

A thornless Manetti. Oh how I wish...... The rose we grow in Western Australia is certainly not thornless. It grabs me every time I mow past it. Lovely, but prickly. The W.A. is a different rose to the Manetti I have seen in California.

Cass's Californian picture in the Photos show thorns.

Peter Beales in his Roses, Harper Collins, 1992, page 342 says "well endowed with dark thorns."

Perhaps mine has been misidentified. I collected it from Civil War era cemetery and fielded the photos of it to people who are good at identifying old roses and they asked me if it was a once bloomer and if it had thorns. It was a once bloomer and had no thorns so was assured it was Manetti. They said if either was not the case, then they were not sure what it was. So I've labeled it Manetti. I guess I should look it up in one of the old rose advisors when I visit Ashdown Roses and Roses Unlimited in a few months, as I know I saw one or both of their offices filled with rose books and see what the they say about Manetti. What ever I have, its from pre 1865 likely, as all the graves in that area were from the 1840's -1860's, and the roses are likely orignal bushes and as I understand, Manetti had it's day as a common understock rose. Seems I have a mystery on my hands.

Bob, my Manetti came from the University of California, Davis, Foundation Plant Services, for what that's worth. It has distinctly reddish canes, it goes dormant well here in Zone 9, and it is well-armed with rather small, sharp, down-curved prickles. When Davis sends out budwood sticks of Manetti, they strip the prickles, but the reddish cane surface is still visible. By going dormant in my borderline Zone 8-9 garden, it demonstrates to me that it has some hardy rose genetics in there somewhere.
