The so-called Everblooming Roses include the Hybrid Tea and Pernetiana groups. They do not bloom all the time, but if kept healthy and growing steadily, one crop of flowers succeeds another at brief intervals.
Elli Hartmann. Hybrid Tea. (Welter, 1913.) Very large, pointed buds and full, well-shaped blooms of clear old-gold, developing lighter shades of pink and yellow; mildly fragrant. Growth remarkable; foliage especially good; hardy and persistent in blooming.
We have found this Rose to act differently in different locations. Some places it is exceedingly good and produces magnificent blooms, at others it balls very badly. But in general it is best in autumn everywhere.

"New Roses for the Garden" by Charles E. F. Gersdorff
Yellow Roses. These are my favorites; perhaps because good yellows are scarce. [...] Elli Hartmann (H. T.), from Welter, Germany, 1913, is a rich old gold in shade. It is distinct and fine, of medium to large size, giving an average amount of bloom which is very durable; in growth is vigorous and bushy.

M. Nicola Welter, rosiériste à Trier-Pallien, a mis au commerce au commencement de novembre 1912 : ELLI HARTMANN (Hybride de thé). Provient d'un croisement de Souvenir du Président Carnot, de Madame Mêlanie Soupert et de Maréchal Niel. Cette variété exposée à Muenchen- Bladbach, sous le numéro 5088, fut unanimement admirée. La plante a une tige droite aussi robuste que le plus fort des hybrides de thé, non grimpants. Le bouton fermé a la forme d'un oeuf; coloris saumon tacheté de carmin. Les fleurs sont grandes, bien remplies et ont une apparence majestueuse. Elles se tiennent constamment droites. La couleur rappelle beaucoup celle de Maréchal Niel : centre jaune vieil or. Les fleurs s'ouvrent bien et se conservent dans l'eau six à huit jours après la cueillette. Parfum exquis. Très précieuse comme fleur de serre, et aussi pour le plein air. Rose de luxe de tout premier choix, dédiée à la fillette d'un gland ami des roses de Grevenbroich.
