Rose Mrs. Pierpont Morgan. For two years we grew a small house of the rose heading this note. It was not a great favorite, for some unaccountable reason, with the city retail florists. We do not encourage retail trade here on our own place, catering exclusively to the wholesale trade. Some persons will drop in, however, occasionally wanting flowers, and because the dealers in Philadelphia did not take very kindly to Morgan, this was the rose offered to retail customers. So well did it please them that we secured orders for delivery at regular intervals— twice a week. In addition to its other good qualities it is an excellent keeper. These customers frequently remarked that the flowers when three or four days old were still in good condition, and when the fresh ones were delivered the older ones were forwarded and presented with evident great pleasure to some less fortunate person who did not have flowers often. For this reason, if for no other, Mrs. Pierpont Morgan ought to be grown to a greater extent than it appears to be, especially in the smaller towns where a florist is a 
combination of grower and retailer.

Mrs Pierpont Morgan, presented in the accompanying engraving, is perhaps the most distinct rose of modern introduction. The fact that it is of American origin is worthy of special note, as hitherto almost all of the best-known varieties of this "queen of flowers" have been of French origin, with more recently a few raised by careful hybridizing in the nurseries of one or two English growers. The rose, like the chrysanthemum and other much-cultivated flowers, has a strong tendency to "sport"; that is to say, it is likely, from some unknown cause, to develop in one special bud some feature which has never before been seen in the variety. It may be a new form of growth in some special part, or perhaps, and most commonly, a distinct coloring. It is to such a sport that we owe the possession of the Mrs Pierpont Morgan rose. The parent of this variety is the well-known and deservedly popular Madame Cusin, and its relationship is patent to anyone acquainted with both, but the new comer differs in several respects. Its color, a clear bright cerise, with a trace of pale yellow at the base of each petal, is more decided and heavier than that of Madame Cusin; in general growth greater vigor is displayed, and the individual blooms attain a size of from four to five inches across, on the average, with petals of good substance and well-scented, which latter cannot be said for all recent introductions. As will be seen in our illustration, the build of the bloom is light and graceful, the reflexing of the petals assisting much to this effect, making it a valuable decorative rose. All these points, together with the good length of stem attainable, assist to place this rose in the front rank of popular sorts, and indeed it is aleardy being largely grown for the cut-flower trade in New York and elsewhere. Although quite distinct from its parent, it is withal somewhat similar to that in its finest condition, and in consequence, the nomenclature on the market is not rigidly followed, and sometimes the one variety is substituted for the other. This variety belongs to the tea-scented section, and is of easy cultivation by ordinary methods, but of course is not hardy out of doors in the north any more than any other Teas. It blooms freely, and last but not least, the color is one that shows up well under an artificial light. Mr John N. May, whose fame as a rosarian is well known, is to be credited with having introduced Mrs Pierpont Morgan to the notice of the public, he having secured the novelty by purchase from H. Miles of New Jersey, in whose place the sport appeared, on a plant of Madame Cusin.

Mistress Pierpont Morgan. — Rose thé. Cette nouveauté qui nous arrive d'Amérique est issue d'un croisement de la rose thé Madame Cusin .... Mistress Pierpont Morgan est d'une croissance vigoureuse, d'un beau feuillage vert foncé et très sain. Les fleurs en sont très grandes, atteignant parfois 0 m. 12 de diamètre, les pétales larges jaunes à la base ombré de rouge cerise, ces deux couleurs s'harmonisent merveilleusement. La floraison est très abondante, et les fleurs ont l'avantage de se conserver longtemps sans faner lorsque la plante est cultivée sous verre. Reste à savoir si on plein air, elle aura le même avantage, car on a déjà constaté que dehors, la fleur n'était pas du tout érectée, mais au contraire très penchée, tandis qu'eu culture chauffée elle se tient très droite.

Mrs. Pierpont Morgan. - Rose tea. This novelty that comes to us from America comes from a cross of the tea rose Mrs. Cusin .... Mistress Pierpont Morgan is a vigorous growth, a beautiful dark green foliage and very healthy. The flowers are very large, sometimes reaching 0 m. 12 in diameter, the large yellow petals at the base shaded with cherry red, these two colors harmonize wonderfully. Flowering is very abundant, and the flowers have the advantage of being preserved for a long time without fading when the plant is cultivated under glass. It remains to be seen whether it is open air, it will have the same advantage, because it has already been found that outside, the flower was not at all erect, but on the contrary very leaning, while heated culture she stands very straight.
