Dr. James Alexander Gamble.  The Rose Named ‘Liberty’. 
….The breeding promise of ’Liberty’ was recognised at once by the late E. G. Hill of Richmond, Indiana.  He bought the American rights soon after it was produced…..’Liberty’ is a brilliant, velvety crimson.  The Hills called their first bright scarlet improvement over ‘Liberty’, 'Richmond', to mark the place of its production.  The Montgomerys of Hadley, Massaschusetts, when they produced an even better, richer crimson ‘Richmond’, called it Hadley.   Dorner, to bring the glory of this rose line back to Indiana, called his glowing crimson rose ‘Hoosier Beauty’.  A few years later, the Verschurens of Holland, in order to have national credit for the deep bright red rose they produced from ‘Hadley’, called theirs ‘Etoile de Hollande’….. 
'Richmond' was by ‘Lady Battersea’, a daughter of ‘Liberty’ and ‘Liberty’ herself;  Hadley had as seed parents both ‘Liberty’ and ‘Richmond’, and ‘General MacArthur’ as her pollen parent;’  ‘Hoosier Beauty’ was by ‘Richmond’ and ‘Chateau de Clos Vougeot’ an outcross;  and ‘Etoile de Hollande’ was by ‘General MacArthur’ and ‘Hadley’…

Hadley (Garden)  One of the most popular reds, but its habit of "Blue-ing" when flowers are opening spoils the value of richly scented, full, shapely ruby-red blooms. Growth is variable; vigorous on some good rose soils, and most disappointing on others. Flowers are long-lasting, and where it thrives Hadley is still a strong favourite. Fragrant. Habit 3. (HT)

Hadley (H.T.) has very large well-shaped flowers of deep rich crimson, borne singly on good stems. Its drawbacks are that the flowers have a tendency to blue with age, and in certain districts the deep green foliage is subject to mildew. Waban Conservatories 1914. Deciduous. Vigorous Growth.

C'est ainsi, observent M. et Mme Landeau, que la variété Hadley, cette belle rose rouge intense qu'accompagne un feuillage brillant, intensifié par les pigments rouges dans le vert des feuilles, ne se plaît pas dans les sols humides. Sur les terrasses échelonnées de leur culture, cette variété pousse et foisonne comme du chiendent, alors que dans des établissements contigus, en contrebas, cette variété ne réussit pas. Elle se montre d'une sensibilité extrême aux affections cryptogamiques, dont on n'aurait pas raison malgré la multiplicité des traitements anticryptogamiques. Tandis que la majorité des variétés de roses demandent des arrosages copieux et des bassinages en pluie, Hadley s'y montre rebelle. Ailleurs, au contraire, le régime des arrosages de cette variété ne diffère pas de celui des autres. Cela dépend aussi de la température de l'eau; celle emmagasinée, chauffée par le soleil, dans les grands bassins est toujours préférable. Il est possible également que le porte-greffe exerce une influence.
