Callas. 



The flowering period for callas being 

 now over, the plants must have a period 

 of rest to recuperate them for another 

 season 's work. The pots, if laid on their 

 sides in a warm, sunny position, will 

 be all right until they need shaking 

 out and starting again early in the fall. 

 Calla tubers are so inexpensive that it 

 hardly pays to raise one's own stock, 

 but if a quantity of the smaller offsets 

 or bulblets are planted out in rich 

 ground they will increase in size sur- 

 prisingly and can be potted up early 

 jn September, if (arefully lifted, so as 

 to keep the roots intact. Well watered 

 and stood for a few days in partial 

 shade, they will grow right ahead and 

 soon fill their pots with roots. 



Hardy Roses. 



The cool, damp summer has suited 

 hardy roses to a nicety and, while many 

 will be too late for the annual crop of 

 June weddings, it pays to give them a 

 little attention just now. If hellebore 

 was applied to the foliage last month it 

 should have exterminated or at least 

 checked the ravages of the leaf roller. 

 Green aphis will now be appearing in 

 the ends of many of the shoots and if 

 not dislodged will speedily destroy many 

 of the buds. Where a good force of 

 water is at command, syringing is the 

 best method of controlling this pest. 

 Failing this, syringe with whale oil soap, 

 being careful to remove the sediment 

 from the top of the can or barrel and 

 to keep the soap and water well mixed. 

 Otherwise, much of the foliage will be 

 burned. 



The rose bug, that worst of all ene- 

 mies of the queen of flowers, has not yet 

 appeared, but a few hot days may bring 

 him .along. Spraying with poison or 

 syringing prove no terrors for him and 

 the tedious method of hand picking must 

 needs be resorted to. Rose bugs are es- 

 pecially fond of white flowers and on 

 this account some growers plant a few 

 Hydrangea paniculata or viburnum 

 around the rose gardens to attract the 

 pests, which will often attack them and 

 spare the roses. 



Mulcljings of cow manure and copious 

 watering are needed to give the roses 

 the needed food supply. Look out for 

 shoots of Manetti or briar stock now 

 appearing. Rub or cut these clean out 

 or they will soon cripple the roses. 



Rambler Roses. 



Rambler roses flower later than the 

 hybrid perpetuals, as a rule, and seem 

 to be rather more immune from insect 

 attacks. Any shoots which have broken 

 weakly should be well cut back. Fre- 

 quently a shoot will appear to break 

 away nicely and, as warmer weather ar- 

 rives, the shoots will turn sickly yellow 

 in color. The effects of the severe win- 

 ter have left but little vitality in these 

 shoots. Where roses of this class are 

 trained on posts, piazzas or on pergo- 

 las, care should now be taken to see 



that they are securely tied. The weight 

 of foliage they carry is daily increasing 

 and high winds accompanied by rains 

 will break them badly. 



The old, popular variety. Crimson 

 Rambler, is more widely planted than 

 are other sorts. The trouble with it is 

 that the flowers fade out badly and the 

 foliage becomes rather unsightly early 

 in the summer. On the other hand, such 

 varieties as Lady Gay, Dorothy Perkins, 

 J* arquhar and other pink forms are fully 

 as hardy as Crimson Rambler and have 

 the advantage of beautiful, showy, green 

 foliage all summer, after the flowers are 



Digitalis Purpurea. 



gone. These pink Ranibler roses are be- 

 ing more and more planted every year 

 and afford a pleasant contrast to the 

 rather ovcrplanted Crimson Rambler. 



Outdoor Work. 



As a good deal of stock will now be 

 in the open grountl, it behooves us to 

 pay considerable attention to this de- 

 partment. Thanks to early rains, carna- 



tions got a good start and are looking 

 well in' the east. Pull out any plants 

 showing signs of stem-rot or other dis- 

 ease and see that the plants are topped 

 as required. 



Violets have also enjoyed the cool and 

 damp May and June and have secured 

 a good start. See that they are kept 

 clean of weeds. Runners will not be 

 produced for a while yet. 



Bouvardias, solanums, eupatoriums 

 and similar plants may need a little 

 pinching to keep them bushy. Asters, 

 «tocks, gladioli and other plants for cut- 

 ting have made rather slow growth up 

 to date, but should now come along 

 quickly if the ground is kept well culti- 

 vated. 



Sweet peas promise to be very good. 

 Have courage even now to thin any 

 which came up thickly. It will pay you 

 to do so. If you mulched them with 

 grass or short manure as recommended, 

 they will stand _a dry spell much better. 



Aquilegias. 



Of the many hardy perennial plants 

 which flower in June, none is more ex- 

 quisitely beautiful than the aquilegia 

 or columbine. If seed has not yet been 

 sown, procure some without delay and 

 sow under sash in light loam and keep 

 well watered. The seedlings should ap- 

 pear in about a fortnight. When the 

 second leaves have appeared* prick them 

 out four inches apart in a disused frame, 

 or, better still, in the field in well pul- 

 verized soil, choosing a damp day for 

 the transplanting. Keep them well hoed 

 and weeded and you will have nice little 

 plants by fall, to flower another season. 



The commercial value of the colum- 

 bine for cut flowers is not half appre- 

 ciated. For bouquet work, or arranged 

 in vases, they are equally good and they 

 last Avell in water. While they are 

 classed as perennials, it is better to treat 

 them as biennials and sow a good batch 

 of seed each summer. Of the various 

 species in cultivation none is more beau- 

 tiful than A. coerulea, the well-known 

 Rocky Mountain columbine, which has 

 violet blue and white flowers. A. chry- 

 santha, bright yellow; A. glandulosa, 

 dark blue with white corolla, and A. 

 Olympica, mauve blue and white corol- 

 la, are other good varieties. No florist 

 will make any mistake in sowing liber- 

 ally of any of the foregoing varieties. 

 Plants and flowers are both good sellers. 



Digitalis. 



This biennial is deservedly popular. 

 While not seen to any extent in our 

 markets, well-grown spikes sell readily 

 and in large vases make an effective 

 display. Even where there is no special 

 call for the flowers, it is always pos- 

 sible to sell a number of plants each 

 spring, as foxgloves are among the most 

 stately and beautiful of haruy biennials. 

 In some localities it is necessary to plant 

 them under sashes during winter, but 

 in well drained land, with a. light coat- 

 ing of leaves or straw, they usually come 

 through safely. Seed sown now will 

 produce big plants by the end of Octo- 

 ber. Sown even a month later, good 

 flowering size stock may be had. When 

 transplanted they should be allowed ten 

 to twelve inches apart in the rows, aa 

 they grow rapidly. On level land, where 

 water may lie, they will not winter and 

 it is much better to lift them and plant 

 thickly in cold frames, transferring to 

 the open ground in April, 



Jn individual beds foxgloves make a 

 beautiful show, They also are splendid
