Ellwanger......did raise a seedling of ‘General Jacqueminot’ in 1885 called ‘Marshall P. Wilder’, the best of his productions. The rose was named for a former president of the Massachusetts Horticultural Society who specialized in hybridizing and growing camellias. A red rose, according to a number of critics very similar to ‘Alfred Colomb’ only better, ‘Marshall P. Wilder’ was still in commerce in 1999. Horticultural editor Marlea Graham asked in 2004, “Is it possible that some of the superior ‘Wilder’ roses are still being sold today as ‘Colomb’?” Yes, it is wholly possible.

780. Marshall P. Wilder, vigorous, Hybrid Remontant. Ellwanger & Barry, 1884. Raised from the seed of Gen. Jacqueminot. It is of vigorous growth, with healthy foliage, flowers large, semi-globular, full, well-formed; color, cherry-carmine, much like a light-colored Marie Baumann, or a shade deeper than Marie Rady, and very fragrant. In wood, foliage, and form of flower, it resembles Alfred Colomb, but the seedling excels that famous variety in vigor, hardiness and freedom of bloom. It continues to bloom profusely long after the other Remontants are out of flower. In brief, it may be described as an improved Alfred Colomb.

Hybrid Perpetual Roses.
Genial Marshall P. Wilder, the author and lecturer, for whom this Rose was named, naturally took a great deal of delight in the flower that bore his name. The variety was developed in 1885, and by bearing the name of a widely-known man, came into instant notice. Then the bright scarlet-crimson color and strong, penetrating fragrance made it immensely popular. The flowers are full, round and extra-large and come freely over a long season. The plant grows vigorously. Marshall P. Wilder Rose somewhat resembles the Alfred Colomb, for which it is sometimes mistaken. Like all Roses of character, the plants well repay the care and attention bestowed upon them, yet they are hardy enough to withstand neglect that would ruin less robust sorts. Whatever else you cultivate in the way of Roses, you should have a few of this distinctly American production that so becomingly honors a noted lover of Roses and other flowering plants. Some Roses are just "flowers"- to be planted and looked at- but this Rose is one to be studied, loved and made a companion during the blooming season.
