[From The Practical Book of Outdoor Rose Growing
, by George C. Thomas, p. 38:] they are budded or grafted on strong briar and other stocks from two and one-half to four feet from the ground... they do require winter protection in colder areas... [p. 39:] an attractive effect is produced by allowing the trailing shoots [of climbers, for instance
] to grow downwards, more or less like the weeping willow tree, and these are called weeping standards... It is believed that Teas are especially prolific when grown in this manner.
[From Fifty Favourite Roses, by Michael Gibson, p. 16:] Ballerina makes an absolutely first-rate standard rose, forming an excellent head, much better than that of many hybrid teas or floribunda roses...
[From A Year of Roses, by Stephen Scanniello, pp. 146-147:] Tree roses, also called standard roses, are often displayed to their best advantage when planted in containers... Tree roses come in heights anywhere from two feet high (most common with miniature roses) to over six feet. There are two forms of standard roses available. One if the common form of a long stem supporting a bushy display of roses, sort of like a large lollipop. The other is a weeping standard, the only style I think worth using.
Tree roses are created by attaching three buds of a rose cultivar to a long straight stem of another rose. The most common stem stock to use is an unnamed rugosa rose variety. Other roses have been used for creating standards, but the rugosa seems to be the strongest, surviving the longest.
[From The Rose Garden>, by William Paul, p. 72: Some people like standard, or tree, roses, some people don't... Paul weighs in on the side that likes them and discusses it at length in his book...]
[From Roses: An Illustrated Encyclopaedia & Grower's Handbook of Species Roses, Old Roses & Modern Roses, Shrub Roses & Climbers, by Peter Beales, p. 108: As standards,] Orange is a popular colour, but in colder areas roses of this shade are best avoided since they tend to be less hardy than those of other colours.
[Frpm The Makers of Heavenly Roses, p. 24: breeder, Jean Sisley, hated standard roses] which he ironically called 'broomsticks'.
