The Weekly Florists^ Review* 



JuMB 30, 1904. 



numbers literally thousands, still Queen 

 Victoria, or the old Whitleyi, stands 

 as one of the best varieties in white. 

 It is one of the popular sorts for the 

 florists, as it is an excellent keeper and 

 a very good shipper. It also keeps well 

 on the plant when used for garden work. 

 The tnle stock is of strong growth and 

 the flowers are of good size. They open 

 two days after Festiva maxima. The va- 

 riety Whitleyi was first described in Eng- 

 land in 1808. The name Queen Victoria 

 is a more modern appellation. 



Modele de Perfection is a pink peony 

 which lias been sold for some years at the 

 Peterson Nursery under this name. This 

 is not the same variety which is sold un- 

 der this name in Europe. Both are pink 

 but the characters are quite different. 

 This variety, however, is worthy of its 

 title. It is of one shade of pink through- 

 out the bloom. It is one of the so-called 

 pineapple centered varieties. The illus- 

 tration shows the broad guard petals, the 

 center 6f the expanded bloom being very 

 compact. It is a free bloomer, every stalk 

 running up to a flower bud and on young 

 plants the amount of bloom is noteworthy 

 Mr. Peterson is of the opinion that this 

 variety is identical with M. Jules Elio, 

 a pink variety sent out by Crousse in 

 1888, and other experts agree with him. 

 At best the diflferences in growth are very 

 slight and might easily be accounted for 

 by differences in the strength of the 

 plants from various sources. 



One of the Crousse varieties of 1880, 



which has proved of exceptional merit in 

 this country, is Madam GeiBsler, very 

 large, late, clear rose color. Tbe plants 

 grow to about tliirty-six inches in height 

 and the blooms are seven inches in diame- 

 ter when fully developed and about five 

 inches deep. 



The sale of plants and cut flowers has 

 increased wonderfully in the last few 

 years, the peony enjoying an era of popu- 

 larity heretofore unknown to this flower. 

 Of course large numbers of plants are 

 moved in the spring, but growers agree 

 that it is very much to be desired that 

 planting be done in the fall and Mr. 

 Peterson recommends that all planting be 

 done in September. He says that plants 

 divided and reset at that time will make 

 one-third more growth the next season 

 than if planted so late that root action 

 does not begin before frost. He thinks 

 this is a great drawback to European 

 importations, as most of them arrive so 

 late that it is impossible to get them 

 started well the same season and it takes 

 two years to find out what they really 

 can do. 



Certain complaints about the failure of 

 plants to bloom satisfactorily have led Mr. 

 •^"Peterson to make some experiments which 

 have convinced him that the seed follicles 

 should be removed from the plants after 

 the bloom has passed. Do not let thorn 

 stay on and wither or it will cut down 

 the amount of bloom the following sea- 

 son. This has been shown by careful 

 tests with plants growing side by side. 



PERLE DES JARDINS. 



This old favorite, wliicli has been some- 

 what neglected during tlie past few years, 

 has seemingly along with its sports, Sun- 

 rise and Sunset, begun to find favor with 

 the public again. A few years ago then; 

 was no rose growing estahlishnient of 

 any note but planted at least onc-Hfth 

 of their rose space to this variety and 

 those who could do it well found it a 

 profitable crop. The pla<-e- where it is 

 now grown in any such (juantities are 

 very few. not l>ecause it cannot be grown 

 as well, although I am convinced thiit 

 it has deteriorated in a measure, but 

 because there lias Iwen little or no call 

 for that color during the past year or 

 two. 



The larger growers finding Ihe mar- 

 ket for this color failing, gradually drop- 

 ped it. while some of the smaller grow- 

 ers still cling to it in a half hearted way 

 and its deterioration, if any. can be as- 

 cribed to neglect, both in the care and 



attention given to it in propagating an.l 

 growing. 



To grow this variety to perfection 

 great care must be exercised in the seloc- 

 lion of wood for cuttings, as in tiie 

 proper choice of wood lies the success <ir 

 failure to produce plants which while 

 giving a robust, vigorous growth will 

 also attain that firmness of foliage and 

 wood capaljle of producing large, well 

 developed buds of good color and form 

 and the smallest percentage of bull- 

 heads. 



To eliminate this propensity to pro- 

 duce bull-heads the wood selected for 

 propagating should be that close-jointe !, 

 firm and well ripened blind wood taken 

 from as near the top of the bush .ns 

 possible, where it has been exposed to 

 sunlight and air. For years during the 

 time this rose was in favor, I tried the 

 experiment of propagating from flower 

 stems, using from one to three eyes and 

 followed up the practice year after year, 

 as the theory was then highly commended, 

 with the view of getting rid of bull- 

 heads. On carefully comparing the re- 

 sults I found that these plants pro- 

 duced thirty-five per cent more bull 

 lieads than the T>Iants from blind 

 wood cuttings. Where the plants 



showed aJtendency to throw bull-head* 

 1 found/it a profitable plan to remove 

 the ercfwn bud and use a lateral instead. 



The soil that seemed to best suit this 

 class of rose was a stiff, fibrous clay with 

 very little manure added. Manure con- 

 taining a large proportion of nitrogen 

 seemed to encourage that rankness of 

 growth favorable to the production of 

 bull-heads, whilst bone meal, lime or 

 wood ashes had the effect of producing 

 a firrtier texture of foliage and harder 

 wood more suited for the development 

 of perfectly formed flowers of a rich 

 color. 



The temperature at which this variety 

 does its best is 62° nights, running to 

 75° or 80° during' bright sunshine. To 

 secure the best results in color and keep- 

 ing qualities care must be taken not to 

 overfeed, especially wi,th liquid manure 

 during the winter months. 



lieing of a softer nature than most 

 roses the buds should be cut close, es- 

 pecially if they have to be shipped a dis- 

 tance, and care should be taken to leave 

 at least three fully developed eyes so 

 that a future crop may be assured. 



If this color becomes as great n favor- 

 ite in the future as it has been in the 

 past we may expect some new varieties 

 on the market, as I am infornied that 

 there are a few seedlings which in point 

 of merit are away ahead of the Perle, and 

 which are maintaining stable character- 

 istics. lllBES. 



PIPING FOR HOT WATER. 



We have an oflSce 12x12 feet; adjoia- 

 ing this is a house 18x48 running east 

 and west; running north and south from 

 this are two houses, one 15x45, the other 

 16x100. The boiler is under the house 

 next the ofiice, but we are thinking of 

 putting in a new hot water boiler and 

 locating it in a pit at least six feet deep 

 at the south end of the long housCj about 

 130 feet from the office. We shall use 

 2-inch pipe mostly. In the house 18x4S 

 we want 50 degrees when it is 15 below 

 zero outdoors; in the house 16x45, 55 de- 

 grees, and in the house 16x100, 53 de- 

 grees. How many linear feet of l^^- 

 inch and 2-inch pipe make a square foot 

 of radiation! Please give the rules for 

 obtaining the amount of radiation which 

 will be required in a house of given di- 

 mensions when the temperature needed 

 and the coldest outdoor temperature are 

 stated. J.' W. M. 



It is not an easy thing to give the 

 rules for computing the heat require- 

 ments for houses with different exposures 

 and situations, which are to be piped 

 with pipe of various sizes. In the first 

 place the piping is based upon the area 

 of the roof and sides of the house which 

 are exposed, the amount of piping de- 

 pending upon the temperature to be main- 

 tained during severe weather. While the 

 area of standard pipe is always the same, 

 Ihe constants for determining the radia- 

 tion needed differ for the temperature 

 required, depending upon the heat used, 

 whether hot water or steam, as well as 

 upon the pressure. It is therefore, quite 

 impracticable to give all the tables ani 

 method by which these factors are deter- 

 mined. The constants used have been 

 worked out by mechanical engineers anil 

 by careful experimental tests in the 

 greenhouse. 



Without, therefore, endeavoi;ing to ex- 

 plain further the method by which con- 

 clusions have been arrived at, I will state 

 that your boiler, which is the keynote of
