Hollyhocks as cut klowers.— We 

 learn Irom the local newspapers that "In 

 recent entertainments given at the East 

 End (a residence part of Pittsburg) single 

 hollyhocks were used as the decorative 

 features. In the arrangements the stalks 

 of the hollyhocks filled umbrella holders 

 and long-necked jars, or rested in great 

 sheaves against cabinets and in alcoves, 

 and in other ways were utilized to charm- 

 ing advantage." 



Double Hollyhocks are not as hardy 

 as the single ones, they are not as vigor- 

 ous or long-lived, and they are much more 

 susceptible to leaf diseases, far betterhave 

 a plain single flower than an ill-favored 

 double one, and an ugly shade of color in 

 a double flower is more unpleasant than 

 it is in a singleone. Notwithstanding all 

 this, however, handsome full double, 

 clean-colored hollyhocks have the warm- 

 est spot in the affections of the people. 

 Hollyhocks raised from seed this fall 

 should bloom next summer; but those 

 sown in spring won't bloom in summer 

 of that vear, 



Flowers ok Paper, Which?— Tiie 

 Gardening IV'orW is somewhat exercised 

 over "the American fashion of selling 

 pot plants rolled up in green, pink, 

 yellow and other colored paper, tied 

 around with narrow ribbons to match. 

 This is not merely for the purpose of pro- 

 tection, so that the purchaser can carry 

 the plant home safely. Oh, no; it is 

 meant for adornment and that the plants 

 may be used for household decoration in 

 such nonsensical and tinsel trappings. 

 ' * This is an attempt to paint the rose 

 and gild the lily." 



Hedysarum .MULTijiT.uM is a little 

 Japanese hardj' shrub with racemes of 

 bright rosy purple flowers, and it is one 

 of the high priced novelties in its line and 

 has a reputation for neatness and great 

 floral beauty. That all may be true 

 enough, but certainly the specimens in 

 Schenley Park don't behave as if they'd 

 be good and contented Americans. VVe 

 mustn't despair, however, we'll try the a 

 under different conditions. Maybe we 

 may j'ct hit uijon what will suit them.

Tin; Prickly Poppy.— L. E. W. sends 

 us two flowers for name. The large 

 white bloom with the glaucous prickly 

 leaf is one of the prickly poppies (Arge- 

 mone), quite pretty plants, natives of 

 California and Mexico, and easily raised 

 from seed in our garden. The little sprig 

 of very small blooms was so much discol- 

 ored as to be unrecognizable. In sending 

 plants for name kindlj- send them direct 

 to us to Schenley Park, Pittsburg, and 

 not to the Chicago office. When sent to 

 the latter place they have to be opened 

 and remailed to us, so that when green 

 sprigs reach us they are apt to be black- 

 ened to such an extent that we cannot 

 tell what they are. And it will help us 

 greatly, too, if when you send the flow- 

 ers you will at the same time tell us all 

 you know about them. 



Single Hollyhocks are "all the rage" 

 in this town, that is we find them inmost 

 every yard, pretentious as well as neg- 

 lected; they fill up odd and neglected cor- 

 ners in company with sunflowers and 

 tawny day lilies, as well as belts and beds 

 in well tritnmed gardens. Apparently 

 they are healthy, happy and hardy, and 

 good perennials, and really they are hand- 

 some. Mr. J. R. Mellon has one of the 

 finest displays in Pittsburg. The plants 

 are in a border 300 feet long by 4 feet 

 wide, along the boundary line of his lot, 

 and in the deep rich land there they make 

 a great sight rising 7 or 8 feet high, 

 with big leaves to the ground. The col- 

 ors comprise yellow, pink, cherry, crim- 

 son, white and intervening shades. In 

 winter a light straw mulching affords 

 their crowns protection, also it saves the 

 little seedlings from injury. In growing 

 single hollyhocks avoid the purples. They 

 have an unpleasant look; clean, clear 

 pinks, blush, white and yellows are the 

 iavorite s ' 



Hypericum Moserianum. — Our nur- 

 sery grounds at Schenley Park are spread 

 on both sides of a high swell of open land, 

 and the ground is of a stiff clayey nature. 

 Near the top, running lengthwise was a 

 nurserybed containing five rows of Hy- 

 pericum Moserianum, one hundred plants 

 in the row. This is the second year they 

 have been there. Last winter, an excep- 

 tionally severe one, they weren't mulched 

 or protected in any way, but their tops 

 were left on them; the result was rather 

 curious; The plants in the two outer 



rows were nearly all winter killed, but 

 those in the three inner rows have all 

 lived, and are now fine big clumps in good 

 bloom; even they, however, were cut to 

 the ground, but they recovered verj' vig- 

 orously. This satisfies us that the plant 

 is not hardy above ground, but with a 

 surface mulch or protection of neighbor- 

 ing bushes it is ()uite hardy at the root. 

 This is enough for us, ,iiid treating it as a 

 spreading herbaceous plant or as an 

 under or front shrub in shrubberies, it is 

 a most valuable acquisition. 



How TO grow hardy flowers.— Look 

 at that group of hardy perennial delphin- 

 iums shown in our illustration, page 325. 

 Isn't that a beautiful picture? and ob- 

 serve how aptly placed the plants are. 

 The common way to arrange delphini- 

 ums in the garden is to set a clump here 

 and there in the border, or run a row of 

 them along the back of the border. Now, 

 if that's the way you grow them, go out 

 into your garden and take alook attheni 

 there, then look at this picture and con- 

 clude for yourself which is the prettier 

 arrangement. The same with the cypri- 

 pediums shown on page 327, if you want 

 telling effect group your plants together, 

 you will then be able to give them better 

 cultural conditionsthanif j'oustuck them 

 here and there through your garden. • Uii 

 trillium picture on front page July 1 issue 

 is another excellent example of grouping 

 plants of a kind together. But mind 

 there is a vast difference between effective, 

 tasteful grouping and bunching a lot of 

 plants together; the bunching process is a 

 very harsh and ungraceful way of using 

 plants. 



Red Spider and Wet Weather.— We 

 all know that hot dry weather is favor- 

 able to the development of red spider, 

 and we are taught that wet weather is 

 inimical to its welfare. The last two 

 summers ('94 and '95) at Pittsburg were 

 exceedingly dry, and red spider was quite 

 prevalent on the trees and shrubs, es- 

 pecially so in the park nursery on a block 

 of Spirsea Billardii and S. Fortunei; but 

 this year, from the breaking up of winter 

 till now, the middle of July, has been un- 

 precedentedly wet and the very opposite 

 to what we should expect as at all favor- 

 able to the spread of spider. Strange as 

 it may seem, nevertheless, those blocks of 

 shrubs that were badly infested last 3'ear 

 are much worse this summer, and to-day 

 there isn't a leaf on one of them that 

 isn't covered with the pest and "brown 

 as a berry," and the red spider is spread- 

 ing. Blocks of trees and shrubs — we have 

 over 200,000 plants in the park nursery 

 —that were clean last year are clean this 

 year except where near the infested ones, 

 but in all cases, our nurserj' foreman tells 

 us, what were infested last year are worse 

 this summer. 



Red Spider on Veranda Vines.— A 

 lady came to us the other day about a 

 fine big pipe vine that covered a trellis and 

 shaded one side other house veranda; its 

 leaves were getting brown, they were 

 covered with red spider. A florist she 

 had consulted told her to wash the leaves 

 with soap and water, but she could never 

 do that. In the case of a big vine that 

 was impracticable advice. She had city 

 hydrant water and a hose, so we told her 

 to get out the hose and attach it to the 

 hydrant, bring it in on the stoop, turn 

 the water full on and et fly at the vine 

 from the inside (the stoop side). Do this 

 twice a day fora while, no stinted draught 

 at all, but a thorough drenthing, aiming 

 the nozzle so as to wash the underside 

 rather than the upperside of the leaves. 

 We have to keep at it till we get off all of
