greenhouse and arc hard to dislodge if 

 they once get a liold, as pansy plants hug 

 the ground. Aphis or no aphis, spray 

 the pansies with u good spray, knock- 

 ing the plants over so as to get at the 

 under side of the leaves; then spray 

 them from the opposite way. Such 

 spraying, with tobacco dust, will clean 

 the insects out. Give pansies a night 

 temperature of 40 to 50 degrees, with a 

 rise of 10 degrees in the daytime. 



KROESCHELLS IN MERGER. 



The Kroeschell Bros. Co., whose boil- 

 ers are used in many greenhouse estab- 

 lishments, and the Kroeschell Bros. Ice 

 Machine Co., of Chicago, have been 

 merged with the Brunswick Refrigerat- 

 ing Co., of New Brunswick, N. J., in a 

 new concern to be known as the 

 Brunswick-Kroeschell Co., with main 

 offices in New Brunswick. The direc- 

 tors of the companies have been in 

 meeting at New Brunswick this week to 

 settle the details of the merger and 

 elect the officers to head the new com- 

 pany. The directors of the Chicago 

 companies are Robert O. Butz, Arnold 

 H. Goelz, Charles H. Kroeschell and 

 Robert A. Kroeschell, while the direc- 

 tors of the Brunswick Refrigerating Co. 



are James W. Johnson, Robert W. John- 

 son, Sidney B. Carpenter, G. H. Wheeler 

 and Walter Jones. 



The manufacture of Kroeschell hot 

 water boilers will be carried on in Chi- 

 cago in a new and larger factory, to be 

 erected at Diversey boulevard and the 

 Chicago, Milwaukee & St. Paul railroad 

 tracks. The Kroeschell carbon an- 

 hydride ice machines will be manufac- 

 tured there also, while the factory at 

 New Brunswick, N. J., will continue 

 making the Brunswick anhydrous am- 

 monia machines. Thus will be united 

 the manufacturing and sales organiza- 

 tions of two of the most popular ice 

 machines in the florists' trade, both of 

 which were described at some length in 

 the article on "Ice Machines for Flo- 

 rists" in The Review of April 13, 1922. 

 The Kroeschell hot water boiler is so 

 widely used in greenhouses that the 

 trade is familiar with its outstanding 

 reputation. 



The Brunswick-Kroeschell Co. is in- 

 corporated with $1,250,000 of seven per 

 cent preferred stock and 30,000 shares 

 of common stock having no par value. 

 In the event of dissolution the preferred 

 stockholders are to receive $125 per 

 share before anything is paid to the 

 holders of the common stock.

PERENNIALS TO PLANT. 



More Suggestions. 



Last week appeared in this depart- 

 ment suggestions as to the sowing of 

 perennials for cutting, with instructions 

 for florists who have not hitherto in- 

 cluded these useful flowers among their 

 stock. If you have available space out- 

 doors, now is as good a time as ever 

 to make outdoor plantings. Not only 

 will you thus amplify your stock for 

 retailing, but you will provide a colorful 

 display that is sure to attract those who 

 see it. If you take orders for planting 

 home grounds — and every florist should 

 who can provide the force to do the 

 planting — you will gain many orders 

 by a plot of bright perennials. 



Campanulas. 



Tlic campanula family is a large one. 

 One valuable for pot culture or cutting 

 is C. Medium, better known as the Can- 

 terbury bell. This would have been bet- 

 ter if sown some time ago, in order to 

 secure strong flowering plants. The 

 Canterbury bells are biennials and the 

 singles are much better for florists than 

 the cup and saucer varieties. Another 

 beautiful campanula is persicifolia, now 

 coming into flower and persisting for 

 many weeks. In addition to the single 

 forms, there are semi-double white and 

 pale blue forms. This is a splendid per- 

 ennial for cutting. C. pyramidalis, the 

 chimney flower, is reliably hardy in well 

 drained land and blooms in August. It 

 also makes a magnificent specimen for 

 pot or tub culture in late summer. 

 Treatment should be similar to that 

 afforded C. Medium. In the way of 



smaller campanulas, the Carpathian 

 bellflower, carpatica, is already in 

 flower and will bloom until December. 

 The flowers are blue or white in color, 

 large and cup-shaped. As the plant 

 onlj' grows eight or ten inches high, it 

 is a fine subject for borderings or rock- 

 eries. Some other interesting cam- 

 panulas are C. rotundifolia, bluebell of 

 Scotland; C. Priscilla, the Alpine hare- 

 bell,' a dwarf -flowering, dainty gem; C. 

 Trachelium, Coventry bell, and C. ra- 

 punculoides, with showy blue, tubular, 

 bell-shaped flowers on stems three to 

 four feet in height. 



AquUeglas. 

 The aquilegias, or columbines, have a 

 grace and dainty beauty all their own. 

 Especially is this true of the long- 

 spurred hybrids, which come in many 

 beautiful shades, such as blue, lavender, 

 pink, orange and white. A. chrysantha, 

 a golden yellow variety from the moun- 

 tains of California, is a true perennial 

 which will last for many years. On the 

 other hand, such beautiful sorts as 

 cferulea, the Rocky Mountain colum- 

 bine, and haylodgensis, hybrids from 

 cffirulea, arc less reliable and usually 

 gradually disappear after the second 

 or third year, so that it is well to sow 

 some seeds each year in order to keep up 

 a stock. For aquilegias sown now, it is 

 the best plan to transplant them into 

 frames and carry them over winter in 

 these, as they are of slower growth than 

 a number of other perennials. 



Dianthus. 



There are some splendid forms of 

 dianthus in full beauty this month. Of 

 these D. barbatus, the sweet williamj is 



fine for cutting. Pink Beauty is of a 

 fine salmon pink color. Other separate 

 colors are to be had, but many prefer 

 mixtures of color. The various forms • 

 of D. plumarius, better known as the 

 pheasant-eyed pinks, are of easy culture 

 and are free bloomers. All carry flowers 

 of a rich, spicy odor. Propagation may 

 be effected by seeds, layers or cuttings. 

 D. deltoides, a small-flowering variety 

 of a rich pink color, makes a superb 

 bordering plant. It also comes in pure 

 white and rosy red shades. 



Pyrethrums. 



Single pyrethrums are splendid for 

 cutting and often come in most useful 

 for Memorial day. The single hybrids 

 of P. roseum are hardy and come quick- 

 ly from seed. A small proportion only 

 of doubles will come from seed, and 

 those once secured should be increased 

 by division of the roots in August. The 

 giant daisy, P. uliginosum, is of a vigor- 

 ous habit and one of our best late sum- 

 mer-blooming perennials, a splendid sub- 

 ject for cutting and one of which every 

 florist should have a few clumps. In or- 

 der to keep it in the best condition, the 

 plants should be divided and replanted 

 once in three years. 



Eryngiums. 



Many amateurs are charmed by the 

 striking, round, metallic-blue flowers of 

 the eryngiums, or sea hollies. The flow- 

 ers are sometimes cut and dried in the 

 same way as everlastings, for winter 

 use. E. planum and E. amethystinum 

 are both good varieties. They attain a 

 height of four feet and flower in July, 

 August and September. Propagation 

 from seed is easy. 



Viola Comuta. 



Among all the low-growing and per- 

 sistent-blooming hardy flowering plants, 

 Viola cornuta, the true tufted pansy, 

 easily holds first place. In northern lati- 

 tudes of this country it blooms from 

 early May until December and proves 

 thoroughly hardy if its location is well 

 drained. The original form carries light 

 blue flowers, but the rich violet blue, 

 v. cornuta atropurpurea, is the finest 

 form. There is also a pure white va- 

 riety. Propagation is best accomplished 

 by division or cuttings. In order to se- 

 cure the best cuttings, cut one or two 

 plants back hard and they will soon 

 throw up a swarm of nice, succulent cut- 

 tings. The flowers of the true cornuta 

 resemble large violets and must not be 

 confounded with those of the larger- 

 flowered bedding varieties. Seeds of V. 

 cornuta are freely produced, but can- 

 not be depended upon to come true. 

 However, cuttings are produced in such 

 abundance and the plants are so easily 

 divided that propagation is a simple 

 matter. 



Lupines. 



The hardy lupines, forms of L. poly- 

 phyllus, are splendid for cutting and 

 come more quickly than almost any 

 other perennial from seed. Pure white, 

 blue and pink colors are obtainable. 

 Moerheimii, the pink form introduced 

 about ten years ago, is of a pleasing 

 shade. Spring-sown plants will nearly 

 all bloom the first year, but seedlings 

 started now will make sizable field 

 plants before fall. When in flower lu- 

 pines are sometimes attacked by aphis, 

 and spraying 'with nicotine is necessary 

 at that season to keep them clean.
