PETER HENDERSON'S CATALOGUE. 81 



The steadily gro-wong taste and demand for fine Roses induces ns this year to give them the most prominent 

 place in our PLint Department. In Eoses, as in all other classes of plants -where there are a great number of 

 varieties, we ■will endeavor to offer only the best — discarding all but the finest and most distinct. We divide our 

 Tea, or ever-blooming Eoses, into three sections or series, graded according to their newness or scarcity. Series 

 1 comprises the newest varieties— all, however, of tested merit. Series 2 contains kinds that have been out 

 for some years, but whose great merit makes them still largely in demand. Series 3, or general collection, is a 

 list of the finest older varieties, many of which are equal to the newer kinds, and to many would be just as 

 satisfactory. Hybrid Perpetuals we place in only two classes — Series 1 and Series 2— because of their being 

 mere limited in the number of varieties. 



A GREAT ADVANTAGE. — yew York florists have a great advantage over others located elsewhere, be- 

 cause the facilities for the importation of novelties at this point are unequaled, and it is an acknowledged fact, 

 that the Eose-growing and general florist business is done on a larger scale and with greater perfection around 

 New York than in any other locality in the United States. Being the great centre of wealth of the country, its 

 exacting taste demands only the choicest, grown to the greatest perfection. 



SIZES. — We are the only extensive Eose-growers who offer Eoses in different sizes. This gives purchasers the 

 opportunity of procuring a plant of large size which will make a show at once, or smaller plants at prices 

 which place them within the reach of all. 



HOW WE GROW OUR ROSES. — Nearly every florist and Eose-grower in this country propagate 

 their entire stock in September and October. This compels them to force them along all winter so as to get 

 them of suf&cient size to sell in the spring. The effect of this forcing is shown when they are planted out in 

 the spring, by a feeble, sickly growth or total loss. We propagate our Eoses in June, July and August, which 

 enables us to grow them to a good size by fall, when we store them away in cold greenhouses until sold in 

 spring. Eoses thus treated have their natural season of "rest,'' and invariably do well when set out in 

 spring. 



TREATMENT WHEN RECEl V ED.— when Eoses or other plants are sent by mail, nearly aU the 

 soil is shaken off to lighten. If it is the season when they can be planted out doors, the ground should be 

 first well dug up and pulverized — the plants then set out should be well firmed about the root, copiously 

 watered once only when planted, shaded for two or three days when the sun is out; no further watering should 

 be done, but a mulch of moss, manure or leaves around the roots would be beneficial. When received (by 

 mail) at a season when they cannot be put out, they should be placed at first in as small pots as possible, 

 sparingly watered until they show signs of new growth. If by express the plants are usually in such condi- 

 tion as to require a size larger pot than they have been growing in. 



INSECTS. — The insects that principally infest the Eose are the Aphis or Green Fly, Eed Spider and Eose 

 Slug. The first can easily be destroyed, either by the application of tobacco water (about the color of strong 

 tea) or snuff; the Eed Spider by Cole's Insect Destroyer or frequent syringing with water. The Rose Slug 

 can be kept off by hand picking or an occasional dusting of the plants with powdered white hellebore. 



MILDEW. — This great scourge of Eoses under glass is easily checked by painting the hot-water pipes with 

 a wash of Sulphur once in two weeks ; or when plants are affected in the open ground UBe the prescription 

 given at page 140, in "Practical Floricvilture." 



DIFFERENT CLASSES OF ROSES. 



THEIR HARDINESS A>D GEJfERAL CHARACTERISTICS. 



MONTHLY OR ETER-BLOOMING.— These are undoubtedly the most satisfactory, as they bloom 

 continuously from the time they are set out until frost. They are not hardy, however, north of Maryland, 

 requiring a good covering of straw or leaves, which should be put on about December. This should not be 

 removed until all danger from severe frost is over in the spring. They should then be " cut " well back, which 

 keeps the plant shapely and induces stronger shoots. 



HYBRID PERPETUALS. — These are perfectly hardy, but do not bloom, as their name would indi- 

 cate, perpetually, as they only give one profuse bloom in June and an occasional bloom throughout the 

 Summer. 



HYBRID TEAS.-See page 83. 



NOISETTE or CLIMBING MONTHLY.— Of all Eoses these are the least hardy. They should 

 never be planted out of doors north of the Carolinas, although in the far South, where they wiU live out the year 

 round, they are grand. They are all well adapted for greenhouse culture in any climate. 



CLIMBING HARDY. — These need no description, as every one is familiar with the old-fashioned hardy 

 climbing Eoses that flower in June. 



MOSS. — Like the Hybrid Perpetuals they are perfectly hardy. Their exquisite beauty and fragrance make 

 them great favorites. Moss Eoses are always higher priced than any other Jdnd, being harder to propagate.
