HORTICULTUR£ 



Decennber 11, 190y 



The variety Bismarck will without doubt supersede the 

 degenerating Caroline Testout, and a correct verdict in 

 this case will be afforded in the coming year when a 

 great number of budded stocks come into bloom. A 

 grand rose which many persons have overlooked is Lady 

 Fair of the La France tint and fine form, which nearly 

 always comes singly on the stalk. Leuchtfeur is re- 

 garded as superior to Grus an Teplitz, and is a good 

 bedding rose, with dark foliage. 



THE JUBILEE EXHIBITION, HAARLEM, 1910 



In the beginning of the month of October about 

 1,000,000 bulbs in variety in 1500 groups and beds were 

 planted in the grounds. The parterre on the north side 

 of the area bordering the Exhibition buildings are 

 located in a formal manner; and the remainder of the 

 area in landscape style. Two large buildings have been 

 erected for special exhibitions. The Exhibition com- 

 memorates the 50th year of the existence of the Nether- 

 lands Society for Bulb Culture. The more unportant 

 home and foreign societies will send deputations. 



CARNATION PAUL MARTIN 



As a variety of the Perpetual flowering class this 

 earnation may be described as a desirable acquisition in 

 regard to size of the bloom, which is very large, of fine 

 double form, and of great freedom in flowering, making 

 the variety a good decorative plant when grown in pots, 

 and a remunerative plant for the florist. The color is 

 rosy-salmon. The plant is readily increased by cut- 

 tings; and hitherto it has been quite free from the car- 

 nation rust and other maladies. 



BEGONIA THE GEM 



This charming novelty is a hybrid variety, the result 

 of a cross of an unnamed tuberous rooted begonia with 

 B. Socotrana. The hybrid has a branched inflorescence, 

 and semi-double flowers of a carmine rose tint, 3 inches 

 in diameter. It is a decided acquisition to the dwarf 

 class of winter-flowering begonias; and obtained an 

 award of merit wheji shown by Messrs. J. Veitch & Sons 

 at the meeting of the R. H. S., on November 9. 



TWO EXCELLENT BOSES FOE THE FLORIST 



These two highly recommended new varieties of 

 Hybrid Tea Eoses are of German origin, viz.. Kaiser 

 Wilhelm II., a cross of Kaiserin Auguste Viktoria with 

 Van Houtte, made by Mr. Nekola Welter, of Pallien, 

 and a seedling — a cross of Frau Lilla Eautenstrauch 

 with Sunset. The first named is distinguished by an 

 erect habit freedom of growth, and dark green foliage. 

 The flower is firey red, velvety very dark central petals. 

 The flowers open readily, and the variety is certain to 

 take a high place among dark colored H. T's. This 

 variety comes into commerce this season. The second 

 variety, likewise a H. T., is of the tint of old gold with 



orange, and is a rose of the future — of first rank. The 

 flower buds are long, the flower very full, and fragrant; 

 valuable as a cut flower and for florists' work. 



ACALTPHA HYBRIDS 



When the two introductions of Mr. F. Sander, viz., 

 Acalypha Sanderiana, and A. Godseffiana came into com- 

 merce, several horticulturists in Great Britain and 

 abroad were of the opinion- that both novelties might 

 form suitable objects for hybridizing. Herrn Eettig 

 wrote in "Die Gartenwelt" in 1899 in reference to A. 

 Sanderiana, that doubtless it would soon— if not already 

 done — be crossed with some species having variegated 

 leaves* which would certainly give rise to a number of 

 useful varieties. Nine years have passed, and we have 

 not heard of any hybrids of these two species, although 

 several hybridists have engaged in the endeavor to ob- 

 tain crosses; and the pursuit seems to have been aban- 

 doned. Sir J. D. Hooker showed years ago that A. San- 

 deriana, N. E. Brown, had been known for some years 

 as A. hispida, Burm. 



Herrn Herman Sandhack, head gardener at Mehlem 

 on the Rhine has given great attention to this crossing 

 of Acalyphas, but without results ; and the vegetation of 

 the seed offered greater difiiculties than the obtaining 

 of it. The latter was in so far associated with difficul- 

 ties from the fact that A. Sanderiana as seedbearer was 

 the only available species and this bears no male blos- 

 soms, or only produces female blooms under certain 

 conditions that lead to pollination. In the summer of 

 1907 he had the satisfaction of obtaining seedlings of 

 A. Sanderiana and A. GodselBana, and some rnonths af- 

 ter vegetating he saw that these seedlings differed in 

 leaf and growth from the parents. In the course of last 

 spring Herrn Sandhack was enabled to discover flowers 

 that differed in color from the dull red of Sanderiana 

 and giving place to pale rose, orange, whitish green, and 

 mignonette tints. He has selected the finest colored 

 varieties, and intends to offer only these to the trade, in 

 the hope that many gardeners and plant lovers will take 

 up their culture which is as simple as that of A. Sander- 

 iana. Some figures of these new varieties are given in 

 "Die Gartenwelt" for November 7 last, viz., A. Cam- 

 phausiana, A. Beissneriana, A. Hessdorfiana, A. Wagner- 

 iana and A. Sandhackiana, all of them differing slightly 

 in habit, foliage, flower color and shape. It would oc- 

 cupy too much space in this journal to describe them, 

 and it will suffice for me to state that the plants succeed 

 under conditions found suitable for the more temperate 

 orchids and adiantums, and later in the year they may 

 be placed in a cool greenhouse along with coleus, pelar- 

 goniums, etc., for several weeks. The plants may be 

 kept for six weeks or longer period of time in corri- 

 dors and apartments, if not deprived of a modicum of 

 sunlight.
