'Manetti' rose References
p116 Griffith J. Buck. Iowa State College, Ames, Iowa. Varieties of Rose Understocks. R. Manettii. In the early part of the twentieth century this was second only to Canina in popularity. Today its use as a stock is practically restricted to greenhouse forcing roses. It produces a vigorous plant which tends to be short-lived. Although considered tender, it has lived through many Iowa winters without protection but has never carried enough wood to produce flowers. It blackspots readily. It is propagated by cuttage and may be grafted or budded with equal success.

The eternal Rose stock question was discussed with the foreman, and I was told that seedling briar gave best all-round results for dwarfs. Manetti is cheap to produce and easy to strike, but, strange to say, cannot be used for any variety having the least trace of yellow in its colouring, as if knocked they invariably come away at the union.
p134. R. Marion Hatton. Understocks in America. Manetti is used to a large extent for forcing Roses under glass, but few garden Roses are grown on this understock today. It produces too many suckers to be popular with our present public.

Mme. Edouard Herriot budded on 'Manetti' shows better growth and will give more blooms, especially on a well-established plant, than when budded on any other stock... Generally, the Pernetianas give poor results on 'Manetti'.
p. 55: Golden Emblem, still the best yellow rose in California, never does make a good union with 'Manetti', and usually dies out in two to three years, unless it makes its own roots above the union... While 'Manetti' is a fine understock for the darker Hybrid Teas... it is fast being raplaced by 'Japanese Multiflora' and 'Odorata'... ['Manetti'] has a nasty habit of throwing out roots from one side of the cutting only, and while it may be a fine plant it looks lopsided to the buyer and quite often has to be classed below No. 1 grade on this account. 'Manetti' also has a short season during which it may be budded; June is the best month, and after July the flow of sap stops almost completely, making it next to impossible to work...

[From an advertisement in the American Rose Annual 1926
, p. viii:] The newer shades in roses such as Coral, Old Gold, Saffron Yellow, Terra Cotta and Oriental Red are obtained by planting Pernetiana Roses
, and these roses are only a success
when budded upon Rosomanes Stock. This distinction is quite noticeable in the rose 'Los Angeles'
which proves a failure when budded upon any other stock... Our Hybrid Tea and Perpetual Roses are budded upon Multiflora
and Manetti Stock... [they note that in their catalog they
] do not pass along the description of the Hybridists as the roses grow in Europe but as they grow in our Nursery, always stating defects as well as merits...
p32-3 …..George Dickson …..a truly magnificent bloom shown by Messrs. Frank Cant & Co. It is indeed a wonderful flower, very large, full and perfect in shape. The bloom was cut from a “maiden” on briar cutting, although Mr. Frank Cant assured me they had equally good blooms on Manetti…..
p121-5 Walter Easlea: Some Reasons Why Roses Fail to Make Satisfactory Growth. ……Roses on the Manetti stock – Many growers, in order to produce large showy plants, bud certain of their Hybrid Teas on this stock. In some instances they do well, but, generally speaking, I would warn all my readers against that stock – at least for Hybrid Teas. I have seen pitiable failures entirely owing to this stock having been used, and more especially with some of the dark Hybrid Perpetuals that have thorny wood.
p127-1 Courtney Page, Vice-President, N.R.S. The Budding of Roses. In this country we practically rely on the Briar and Manetti stocks, but the Continental growers use also ……
p128-1 The Manetti stock is good for some of the H.P.’s and H.T.’s and has the happy knack of producing large plants the first year; but it is not a lasting stock, and should only be used for maiden plants. Its disadvantage is, that it will not move well, and unless the union of the stock and scion is planted a couple of inches or so below the ground the plant will die, consequently its use is rapidly declining.
p111-1 E. G. Hill. Roses in the United States. Nearly all our growers now prefer plants grafted on manetti for indoor work, as they produce a stronger growth, and are not liable to the root diseases of own-root stock; some of the yellow-flowered sorts, like ‘Perle des Jardins’ and ‘Sunburst’ and some others, have an inclination, as the season goes on, to canker at the union, but nearly all of our forcing varieties do admirably on Manetti.
p123-2 George M. Taylor, Rose Growing in Scotland. ….The Manetti, although it had been in England for twenty years, had at that time – I am writing of 1850 – scarcely reached Scotland.

"Hybrid Stock for Rose Propagation" (Paper read before the American Rose Society by Dr. W. Van Fleet)
We have hitherto accepted the stocks most approved by European growers as without question the most available, and for greenhouse commercial work the Manetti Rose of Hybrid China parentage, may always be most useful; but for outside planting both Manetti and Dog Brier have proven dismal failures under our climatic conditions.
The latter does not thrive at all, and the former, while vigorous enough, suckers badly and ceases growing too early after dry summers to encourage late blooms in those varieties disposed to autumnal flowering.
Manetti roots are very fibrous, forming a perfect mat in rich, moist soil; but they run shallow and are quickly affected by drought. They drink greedily soluble nourishment, but seem unable to extract much plant food from dry soil. The common experience with Roses worked on Manetti is that they are troublesome and short-lived, unless so planted as eventually to throw out an adequate root system of their own. The great majority of the imported budded Roses are discarded after blooming a season or two, and the remaining plants seldom develop into the strong, vigorous specimens we have a right to expect.

The Manetti Stock.— Often I have reason to wish that Signor Manetti of Naples had never been born or given his name to the wretched Rose stock that bears it, as among my blighted hopes is a wall of Marechal Niel Rose, the plants on which have remained "as they were" at first for the last five years; but this year beside one of them is in bloom the poor Manetti Rose, on which the Marechal was grafted, and, as the Tea Rose will not grow, the Manetti begins to take its place. In some soils and conditions, the Manetti may give some apparent advantages for the first year in making the plant grow rapidly, and perhaps giving one or two flowers to be cut off for a show, but afterwards it is all the other way ; the Rose fails on it. and Tea Roses do not grow on it at all. It is quite distinct in nature from them, and nurserymen who use the Manetti for Tea Roses do no good to their own art or to gardens. People ordering Tea Roses should be careful to order them never to be sent on Manetti stock. But even if they do so they may be disappointed, as the large growers have often to buy from others and so send out Tea Roses on the Manetti stock, an absolutely sure way to prevent the Roses growing or ever showing their extraordinary beauty.
Why do trade-growers do this sort of thing to the injury of their own art and the loss to the buyer who supports them? Unfortunately routine takes hold of every business and has taken deep hold of this to its real injury. Roses are not only propagated by the trade for the garden, but also for forcing, for sale, and for showing; and it is the quickest way to make a presentable growth that is taken. In various cases the plant is only wanted for one year, as when florists want to get strong blooms and throw the plants away afterwards. In this case the life of the plant does not matter, but to the private grower the result could not be worse.
