766 RHODODENDRON. THE ENGLISH FLOWER GARDEN. 



RHODOTHAMM'S. 



in the south of Ireland, in Fermoy, sends 

 to T/ie Garden the following account of 

 the kinds he has found to do well there 

 quite hardy without protection and also 

 of his failures : 



"As I have taken much pleasure in 

 cultivating and hybridising Rhododen- 

 drons for about twenty-five years, espe- 

 cially with a view to acclimatise those of 

 Sikkim and Bhotan, I think the results at 

 which I have arrived may be interesting. 

 In order to avoid occupying too much 

 space, I shall first give the names, as 

 furnished to me, of those varieties which I 

 have found perfectly hardy trees without 

 the slightest protection, although some of 

 those which bloom early (about March) 

 have their flowers occasionally spoiled by 

 the spring frosts : 



" Alpinum ; ^Eruginosum ; Anthopogon ; Arboreum 

 album ; Arboreum roseum, very beautiful ; Arboreum 

 nepalense ; Barbatum, magnificent ; Calyculatum ; 

 Camelliaeflorum ; Campanulatum;Campbelli ; Campylo- 

 carpum ; Ciliatum ; Cinnamomeum ; Cinnabarinum ; 

 Crispiflorum, not bloomed ; Eximium, fine, like Falcon- 

 eri ; Falconeri, grand ; Fulgens ; Falconeri superbum, 

 not bloomed ; Glaucum ; Hodgsoni, grand, has not yet 

 bloomed ; Hookeri ; Keysi ; Lanatum ; Lancifolium, not 

 bloomed ; Metternichi ; Massangei, beautiful bloom 

 this year ; Niveum ; Nobile, a grand plant, never 

 bloomed ; Ochraceum ; Roylei ; Virgatum ; Wallichi, 

 I think same as Niveum ; Wighti. 



" The following were more or less 

 injured last spring (those marked * I have 

 not yet succeeded in acclimatising) : 



" Argentum, much injured, growing well, not bloomed 

 yet ; Aucklandi, much injured, growing well, bloomed 

 well in 1878-79-80; Calophyllum, apparently 1 killed, 

 but growing well ; * Dalhousianum, I do not give this 

 up ; * Edgeworthi, I do not give this up ; Formosum 

 Gibsoni, much injured, but growing well ; Jenkinsi, 

 much injured, doing well, never injured in twenty years 

 previous ; Kendricki, I doubt its name ; Longifolium, 

 much injured, growing well, has never bloomed ; 

 Lindleyanum, much injured, growing well ; Maddeni, 

 much injured, growing well (I see no essential difference 

 between this and Jenkinsi ; centre of Jenkinsi flower, 

 rose, of Maddeni, yellow) ; Nilghiricum not bloomed, 

 much injured ; * Nuttali, many plants killed, I fear 

 hopeless ; Thomsoni, much injured, but growing ; 

 Windsori, very much injured, but growing well. The 

 last two plants appear to me less hardy varieties of 

 R. arboreum. 



" I have not included any European 

 hybrids in my list, of which, between 

 Himalayan sorts alone, I know many, and 

 have a great number of my own rearing 

 also, and the reason I do not give up 

 Dalhousianum and Edgeworthi is that I 

 have seedlings from crosses of them which 

 promise well to be hardy, one especially, 

 between Edgeworthi and, I think, Calo- 

 phyllum, which only lost its bloom-buds 

 last spring, I am very proud of; its 

 fragrance is far beyond any I know 

 Rollisson's fragrantissimum and Lindley- 

 anum being, so far, the best. I have 

 named it the Empress of India in honour 

 of our Queen. H. H." 



RHODODENDRONS IN SCOTLAND. 

 Indian Mountain Rhododendrons may 

 not only be successful in the southern 



parts of England and Ireland, but very 

 fine flowers have been sent me from Scot- 

 land, (Stonefield, Tarbert, Argyleshire), 

 kinds thriving there that do not always 

 | prove hardy in the south. Mr. D. Robert- 

 son, who sent the flowers, said the effect 

 produced by them was very fine, and the 

 following kinds have flowered in that 

 place without any kind of protection : 

 Falconeri, arboreum, arboreum alburn^ 

 niveum, cinnumomeum, Campbelli, cam- 

 pylocarpum, Thomsoni, barbatum^fulgcns, 

 Wallichi) ciliaium, Roylei, Edgei^orl/ii. 

 glaucum, Gibsoni, candelabrum, setosinn* 

 an d pum Hum.

EHODORA (Canadian Rhodora}.R. 

 canadensis is a pretty deciduous bush, 2 

 ; to 4 ft. high, allied to the Rhododendron, 

 a native of the swamps of Canada, hardy, 

 and needing a moist light soil, though it 

 prefers peat. In very early spring it 

 has clusters of rosy-purple flowers before 

 the leaves unfold. 



RHODOTHAMNUS. R. chamcecistits 

 is a beautiful little alpine bush very rare 

 in gardens and rather difficult to cultivate. 

 It is less than I ft. in height with ovate 

 leaves from a quarter of an inch to half
