Three events of national importance and 

 interest are yet on the program for June. 

 They are. the annual gatherings of the 

 American Seed Trade Association at 

 Washington, D. C, June 23, 24 and 25 : 

 the American Association of Nurserymen at Cleve- 

 land, Ohio, June 24, 25 and 26; the American 

 Sweet Pea Society, New York City, June 27 and 

 28. The programs of the seed trade and sweet pea 

 meetings we have already published and in this issue 

 we now present the program which has been prepared 

 for the nurserymen. As usual, it provides a veritable 

 feast of good things from which no progressive nur- 

 seryman can afford to absent himself. If you are in- 

 terested in the nursery trade don't fail to read this 

 prospectus through carefully and we believe you will 

 heartily agree with us that it is well worth the co.st of a 



trip to Cleveland. We have always considered the privi- 

 lege of a visit to Storrs & Harrison's at the neighboring 

 town of Painesville and an hour or two in company of 

 Robert George alone worth the trip to Cleveland. The 

 nurserymen of today are well skilled in the art of inter- 

 weaving rela.xation and amusement with serious busi- 

 ness and we are almost envious as we think of the good 

 time ahead in Cleveland. 



Those of our readers who took especial 



"Special days" interest in the recent Spring Flower 



as show .Show at the Grand Central Palace, 



promoters New York City, may recall that one 



day in the week was set apart on the 

 initiative of the Brooklyn florists, as Brooklyn Day and 

 that as a consequence the Brooklyn press whooped it up 

 lieartily and the Brooklyn people and the Borough officials 

 turned out with much enthusiasm on the afternoon and 

 evening of that day. Anyone who attended the show on 

 Brooklyn Day was given plenty of reason to realize most 

 emphatically that Brooklyn is "on the map." The report 

 of A. L. Miller (who was a prime mover in the affair), 

 before the New York Florists' Club last Monday night, 

 was received with much approbation and favorable com- 

 ment and the suggestion that other places, such as Jersey 

 City, Newark, etc., might well follow the example of 

 Brooklyn at the next show, was heartily applauded. The 

 idea has so much to commend it that we feel called upon 

 to draw attention to it in our editorial notes with a view 

 of possibly awakening a wider interest in this most ex- 

 cellent means of publicity and increased popular support 

 for flower shows, in New York or elsewhere. Its avail- 

 ability as a stimulation for flower shows, in the direction 

 in which flower shows are proverbially weak, is easily 

 apparent. But, if you are disposed to try it out, remem- 

 ber that you must have a few hustlers who will take 

 off their coats and work unselfishly, with absolutely no 

 thought of personal or trade advantage. 



A most valuable contribution to gar- 

 The regal dening knowledge is the extract which 

 family among ^^e publish this week, from the Ar- 

 shrubs nold Arboretum of Popular Informa- 



tion on the hardy evergreen rhododen- 

 drons. The evergreen rhododendrons are indisputably 

 the regal family among garden shrubbery wherever cli- 

 mate and soil are adapted to their culture. As is com- 

 monly known, they will not thrive in limestone soil but 

 we believe, nevertheless, that they might be much more 

 generally cultivated than is the case. Mitch of the prev- 

 alent ideas concerning the unreliability of rhododen- 

 drons as hardy garden subjects is due to the planting 

 of tender varieties or of hardy varieties grafted on ten- 

 der stock, enormous quantities of which are imported 

 from Europe every year for forcing purposes, for auc- 

 tion sales or department stores. The list of varieties 

 given in the Bulletin might safely be enlarged by the 

 addition of quite a number of equally trustworthy varie- 

 ties, but it is a good reliable one and the sorts mentioned 

 are all in perfect form this season in the neighborhood 

 of Boston after a winter of great severity, the thermome- 

 ter registering at times fifteen to eighteen degrees below 

 zero. The copious late rains of last fall are believed 

 to have been a great help to these plants. Some shade 

 from the rays of the morning and noon sun is a requi- 

 site for the rhododendron and a generous mulch of leaves 

 every fall, which is allowed to remain and decay, is an- 

 other requirement. We think a mistake was made in 

 omitting from tlie Arboretum list that old champion 

 Caractacus. For hardiness, rapid growth and profusion 

 of bloom it has no superior thus far, and if we were to 

 select but three, tliis would be one of them. _
