THE DAWSON ROSE 



for several years but it never blooms ex- 



You cannot get them in bloom at Fal- 

 mouth by the first of May, nor probably 

 by the first of June either, no matter 

 when you sow them out of doors. North 

 of New York sweet peas should not be 

 sown before the end of October. If sown 

 earlier and so that they will grow some 

 inches above ground before winter sets 

 in even under a fair mulching they are 

 apt to get killed in winter. But sown in 

 late fall they start very early in spring 

 and seem to have great power of resist- 

 ance as regards frost in spring. 



FERENNIflL rflLOXES-flURflTUM LILIES. 



F. C. C, Bath, Maine, ask; 1. "What 

 are the colors of Phlox sutTriitkosa'i hre 

 they as fine as those of P. decussala? 

 Where can we get the plants, as we fail to 

 find them catalogued?" 



.4ns. Phlox suffruticosa is a syn. of P. 

 glaherrima suffruticosa, a native plant. 

 Phlox clecussata is a syn. of P. maculata, 

 also a native of this country. Phlox 

 paniculaia is likewise indigenous in this 

 country. These three species have given 

 rise to the many splendid perennial 



phloxes of our gardens that bloom be- 

 tween June and September. And the 

 three have become intermixed beyond 

 recognition. The June and July phloxes 

 mostly lean to P. glaberrima and P. 

 maculata, and the large later ones to P. 

 paniculata, so that in a garden sense 

 there is practically no distinction between 

 P. suffruticosa and P. clecussata, they are 

 the early phloxes. 



2. "One of the finest of my auratum lily 

 stalks, heavily budded, turned yellow and 

 died as the buds were trying to expand. 

 We could not dig around it now without 

 injury to the others to ascertain the 

 cause and would like to know if the May 

 beetle larv.-e ever trouble the auratum 

 roots. The others are doing finely." 



Ans. It may be, but we hardly think 

 that the May beetle's grub is the cause.

PLflTyCODON ORflNDIFLORllVl. 



L. G. C, Ya., writes: "W. C. Egan, 

 page 31i;S, says ' Platycodon grandiflorum 

 is a gem in any collection, blooming from 

 July 4 until Septcml)er.' I have had it 



-■pt once for i 



Is it; 



manage- 



Ans. Both the typical blue flowered 

 form, the white (dingy white), single and 

 semi-double, and the dwarf form known 

 as Mariesi, have been in bloom at 

 Dosoris since the first of July, and have 

 every appearance of keeping in bloom for 

 some weeks yet; they are in their best 

 estate during the second and third weeks 

 of July. Towards the last, the blossoms 

 are fewer than when in the flush of their 

 beauty. It is not bad management on 

 your part, it is simply a quicker maturity 

 (m the part of your plants. 



"Hypericum Mosekianum, he says 

 re(|uires a cold frame in northern Illinois 

 for winter. Does it with you?" 



Ans. No. Several plants of it growing 

 in an open border at Dosoris, and left un- 

 protected last winter, are now in lovelv 

 bloom. They were killed back to the 

 ground, however, and we are satisfied 

 that it would have been greatly to their 

 advantage had they been well mulched 

 over winter. As the climate at Highland 

 Park (near Chicago) III., isn't nearly as 

 favorable (or wintering somewhat tender 

 ])lants as that of Dosoris, the protection 

 of a cold frame there in winter for this 

 pretty plant was a wise provision. 



Wilting of Lemon Verbe.\a and rose 

 geranium when cut. E. S. P., Chestnut 

 Hill, Philadelphia, writes: "Please give 

 directions as to the proper time and wav 

 of cutting lemon verbena and rose gera- 

 niums for putting in water in the house. 

 Mine so often droop, although I carry a 

 jug of waterto the garden with me to put 

 them into as soon as cut." They wilt 

 because their evaporation is greater than 

 their absorption. If cut in the morning 

 they are less likely to wilt than if cut in 

 the heat of the day, but wefindthat those 

 cut in the afternoon even plump up rapidlv. 

 The moment they are cut thev should be 

 plunged bodily, overhead, into a pail or 

 tub of water, and left there a minute or 

 two, or long enough to plump up stiff, 

 if they are at all wilted. If left to wilt 

 much before being set in water it isn't an 

 easy matter to plump them up. Shade, 

 or overcrowding, or overfeeding, produces 

 a soft, sappy wood that wilts most as 

 soon as it is cut. 



"Anemone svlvestris," writes F. N. 

 B., "is an utter failure with me. ' Treat 

 it as a biennial by raising a fresh lot from 

 seed every year for blooming the next 

 year. True it is a perennial, but like 

 columbines, delphiniums, hollyhocks, 

 sweet Williams and foxgloves, they be- 

 have b st treated as biennial. 



Roses. 



T«E DflWSON ROSE. 



The rose figured was planted in 1893, 

 and the photograph from which your 

 engraving was made was taken June l-t, 

 1S9+. When planted in 1893 it was just 

 out of the propagating bench, so it may 

 be seen that it is very vigorous in its 

 habit of growth. It was raised by Mr. 

 J. Dawson, of the Arnold Arboretum, and 

 is a cross between Rosa multiiiora 

 Japonica and the hybrid perpetual General 

 Jacqueminot, the first named being the 

 seed parent. Its foliage is of a darker 

 green than that o( multitJora and shining 

 as if varnished; the thorns are reddish in 

 color, the flowers semi-double and borne 

 in clusters of ten to thirty or more, and
