New Rose, Mrs. Potter Palmer, of Poehlmann Bros. G). 



be sold to almost anyone with an as- 

 surance that they will grow well. The 

 flowers are white, yellow, red and crim- 

 son and are produced for a long time. 

 Plant an inch deep and allow eight or 

 ten bulbs to a 6-ineh pan. Give full 

 sunshine all the time. 



There are few more beautiful bulbous 

 flowers than ixia and spiraziis. Their 

 graceful habit, with slender, gladiolus- 

 like leaves and spikes of star-shaped 

 flowers in a wide range of colors, is 



very attractive to critical flower buyers. 

 They succeed well in 6-inch pots or 

 pans, which should be well drained. 

 Keep them in a coldframe until Novem- 

 ber ; then place them in a cool, airy 

 house, well up to the light, where the 

 night temperature does not exceed 50 

 degrees. Water sparingly until growth 

 is well advanced, then more freely. The 

 best ixias are I. craterioides major and 

 1. rosea plena Wonder. Tritomas want 

 similar treatment to ixias. C. W. 



IN CARNATION HOUSE, 



Can a house be built 22x150 feet and 

 heated with hot water so that there will 

 be a difference of 10 degrees in the 

 length of the house? If this can be done, 

 would it be practical to grow a variety 

 of stock in it? I am thinking of roses 

 at one end and carnations at the other. 



J. A. F. 



It is neither satisfactory nor profit- 

 able to grow carnations and roses in the 

 same house and practically impossible 



to run such at a temperature to suit 

 both. The most practical way would be 

 to divide the house by a partition and 

 attach a few extra runs of pipe in the 

 rose section, sufficient to keep the tem- 

 perature up to the normal, 58 degrees 

 during zero weather. 



Some varieties of carnations can be 

 grown successfully at 45 to 48 degrees, 

 but we have no roses at present under 

 glass culture that can be grown prof- 

 itably lower than 56 to 58 degrees, and 

 as the amount of moisture in the atmos- 

 phere for roses is in excess of that re- 

 quired for carnations it will easily be 

 seen that the sections should be sep- 

 arated, both on account of temperature 

 and condition of atmosphere. Bibes. 



ROSE MRS. POTTER PALMER. 



In this week 's Eeview there appears 

 an illustration of the new rose, Mrs. 

 Potter Palmer, the photograph having 

 been made from a vase exhibited by the 

 E. Wienhoeber Co., Chicago, during the 

 autumn opening, the last days of Octo- 

 ber. This rose is to be introduced next 

 season by the Poehlmann Bros. Co. It 

 is a sport of Chatenay and has the char- 

 acteristics of that variety, save that the 

 color is a much deeper pink. The gen- 

 eral pubUe, as well as the trade, con- 

 siders the color a distinct improvement 

 on Chatenay, so that it is likely that in 

 a few years the old variety will have 

 largely given place to its deeper-colored 

 sport. The naming of the rose for Chi- 

 cago's society leader was an excellent 

 business stroke. The better class of 

 flower buyers in Chicago have been ask- 

 ing for the variety to such an extent 

 that the Poehlmann Bros. Co. has been 

 unable to supply the demand for the cut 

 flowers since the flower show exploita- 

 tion of the Mrs. Palmer rose began. 



MILDEW. 



I enclose several leaves of Maman 

 Cochet rose which you will note are dis- 

 eased. Please tell us what it is and what 

 to do for it. We have been treating it 

 as mildew. E. M. R. 



You are quite correct; the trouble is 

 mildew and if you had carried out in- 

 structions as recently given fully in 

 the Review you could not possibly have 

 this pest in your houses. It does not 

 matter what variety of roses you grow; 

 if you treat them right in all respects 

 you can, by the sulphur remedy, soon 

 clear your houses of mildew. 



This pest is the ordinary corollary of 

 keeping the stock coddle(i. By this 1 

 mean all kinds of treatment approach 

 ing greenhouse treatment — shading the 

 glass, moist atmosphere, want of ventila-
