The Rorists' Review 



15 



Our Madonna, umbellatum, rubrum and 

 auratum lilies are in two beds, both of 

 which are affected, but the other beds 

 do not appear to have much, if any- 

 thing, the matter with them. I have 

 sprayed the lilies with Bordeaux mix- 

 ture, but it does no good. If the bulbs 

 were on gravel, would that cause the 

 trouble, or would too much rain do it? 

 We have not been troubled with this 

 befo|;^e. We shall greatly appreciate 

 any information you can give as to the 

 cause and the remedy. J. K. — Wis. 



BOSTON SWEET PEA SHOW. 



The annual sweet pea show in Horti- 

 cultural hall, Boston, July 10 and 11, 

 was smaller than usual and competitors 

 were few. The exhibits, however, were 

 of superb quality, the majority of the 

 flowers being produced on disbudded 

 plafits. The recent torrential rains had 

 ruined most of the local fl6wers; other- 

 wise the exhibition would have been a 

 grand one. In addition to sweet peas, 

 there were large displays of hardy 

 lilies, Japanese irises, herbaceous 

 Tj^ants, hollyhocks, etc. 

 ^ Awards in the principal sweet pea 

 classes were as follows: 



Twenty-five sprays, white — Edwin Jenkins, 

 Lenftx, Mass., first, with Constance Hinton; A. 

 J. Dorward, gardener to Mrs. T. J. Emery, New- 

 port, R. I., second, with Etta Dyke. 



Twenty-five sprays, crimson or scarltt — E. 

 Jenkins, first, with King Edward Spencer; A. J. 

 Dorward, second, with Debbie's Scarlet. 



Twenty-five sprays, carmine — E. Jenkins, first, 

 with Kosabelle; A. J. Dorward, second, with 

 John Ingman. 



Twenty-five sprays, yellow — E. Jenkins, first, 

 with Dobble's Cream; George Melvln, gardener 

 to Col. Cbas. Pfaff, second, with Primrose Spen- 

 cer. 



Twenty-five sprays, blue — E. Jenkins, first, 

 with Leslie Imber; A. J. Dorward, second, with 

 Alfred Watkins. 



Twenty-five sprays, blush — E. Jenkins, first, 

 with Lady Evelyn Eyrt'; A. J. Dorward, second,

Tv/enty-flve sprays, lavender — E. Jenkins, first,

 play of flowers from Mrs. E. M. Gill. 

 Farquhar & Co. received a silver medal 



for an imposing collection of herbaceous 

 plants. They also had a large table 

 of the new Lilium regale, or inyriophyl- 

 lum, awarded honorable mention. 

 Julius Heurlin received a first-class cer- 

 tificate for a new lilium, L. Philadel- 

 phium X L. bulbiferum, spikes carrying 

 twenty-four to thirty-two flowers and 

 buds each.

 medal for their fine group of herba- 

 ceous plants. W. N. Craig was awarded 

 a cultural certificate for Trachelium 

 caeruleum. George Melvln received a 

 silver medal for Odontoglossum Iseve. 

 There was a grand display of small 

 fruits and vegetables. As showing how 

 excellent competition was, there were 

 no less than thirty-six entries for fifty 

 pods of peas. J. O. Christensen won 

 for the best collection of twelve varie- 

 ties of vegetables. The Boston Myco- 

 logieal Club had a nice table of fungi. 



The next prize exhibition occurs Au- 

 gust 7 and 8. Special features will be 

 gladioli, phlox, tuberous begonias, 

 asters and annuals, with numerous 

 fruits and vegetables. 



DISEASE ON HABDY LILIES. 



I am sending you under separate 

 cover a specimen of our Madonna lily. 



The shoots of Lilium candiduiii, or 

 the Madonna lily, were badly diseased. 

 It is not at all unusual to find this 

 beautiful hardy white lily affected in 

 this way. The trouble is due less to 

 the soil than to atmospheric conditions. 

 All lilies dislike a gravelly soil, and 

 practically all prefer soil of good 

 depth. "Either peat or loam will grow 

 them successfully and the addition of 

 considerable sharp sand is a decided 

 benefit. All like good drainage. L. 

 candidum should be planted only four 

 inches deep; other sorts, like speciosum, 

 auratum, tigrinum, umbellatum, etc., do 

 better if covered eight to twelve 

 inches. The cooler and moister the 

 roots are, the better they will do. 



The disease on candidums, and to 

 some extent on other lilies, is due usu- 

 ally to hot, damp and sunless weather, 

 which is ideal for the development of 

 fungoid diseases. It is of little use to 

 spray after the disease Las appeared, 

 but if the plants are sprayed with Bor- 

 deaux once a week from the time they 

 appear above ground until the flower- 

 ing season, you can ward off the dis- 

 ease. This means considerable labor, 

 but prevention is better than cure. I 

 do not know whether you mulch your 

 lilies or not. If not, do so, and note 

 how much better they succeed. Rotted 

 leaves, old manure and cocoanut fiber 

 are all good for this purpose. C. W.

Bouvardias. 



Bouvardias will now be making a 

 good outdoor growth. They should 

 have a pinching not later than July 20, 

 and in the case of that finest of all 

 varieties, B. Ilumboldtii, it is well to 

 rub out a lot of the weaker shoots. All 

 then remaining will run up to fiower. 

 The major portion of these weak shoots 

 would come blind, anyway, and it is 

 far better to rub them out. Keep the 

 ground well cultivated about them and 

 be sure to bench or pot the plants be- 

 fore the night temperatures fall below 

 40 degrees. It does not need actual 

 freezing to kill the buds on bouvardias. 



Genistas. 



Genistas are now making rapid 

 growth. If they are wanted of sym- 

 metrical form, the shears must be used 

 on them once in two or three weeks. 

 There is a tendency to grow these 

 plants more naturally, and certainly 

 such plants appeal more to critical buy- 

 ers than the topiary-like, headed in 



plants which are usually seen. Be sure 

 the genistas are not allowed to suffer 

 from drought; they enjoy syringing 

 during hot weather. 



Show Pelargoniuics. 



As the show pelargoniums pass out 

 of flower, lay them on their sides out- 

 doors. If the weather proves excep- 

 tionally hot and dry they may need 

 a hosing over, but usuall}' this is not 

 necessary. They will become well rip- 

 ened up toward the end of August, 

 when they can be pruned back, and, 

 after new growth has started, can be 

 shaken out and repotted into much 

 smaller pots. 



Trachelivun Caeruleum. 



Trachelium caeruleum has proved to 

 be a useful jilant for summer flow- 

 ering. It is best treated as a biennial. 

 If seed is sown now and the plants are 

 kept potted along, they will flower next 

 .June and July in 6-inch or 7-inch pots, 

 or. if larger ones arc desired, even 

 small tubs may be used. The trache-
