HORTICULTURE

Notes from the Arnold Arboretum 



Among the new Chinese Honeysuckles there is one 

 which belongs to the most beautiful of all climbing 

 Honeysuckles. This is Lonicera tragophylla, a species 

 allied to L. Caprifolium, but with much larger bright 

 yellow flowers in many-flowered clusters. It is a vig- 

 orous growing vine with oblong bright green and lus- 

 trous leaves from three to four inches in length. The 

 flowers are the largest of any Honeysuckle in cultivation 

 but one which is mentioned below and measure two and 

 a half to three inches in length: tliey appear at the end 

 of the branchlets in ten to twelve-flowered clusters sub- 

 tended bv a pair of connate leaves forming a roundish 

 disk and are bright 3'ellow. About its hardiness in this 

 latitude we cannot yet speak definitely, as our plants 

 have not yet been tried out of doors, but in England it 

 has proved perfectly hardy and has flowered profusely. 

 The species which has the largest flowers of all is L. 

 HUdehranJiana from Burma, with orange red flowers 

 from four to seven inches in length; unfortunately it is 

 not hardy here, though it is doing well in California. 

 Of the other recently introduced Chinese species none 

 seems to surpass in beauty the best of the species al- 

 ready in cultivation. The climbing Lonicera subae- 

 qualis resembles the western L. ciliosa, while Lonkvra 

 Henryi is allied to L. japonica, but has narrower leaves 

 and smaller red flowers not much more than half an inch 

 long. Lonicera lanceolata is an upright shrub allied to 

 L. orientalis with oblong-lanceolate leaves from two to 

 three inches long and small lilac flowers followed by 

 black fruits. Lonicera MaacMi podocarpa is not quite 

 as beautiful as the type which is one of the finest Bush 

 Honeysuckles, but still too little known. Lonicera 

 mucronata is a low shrub allied to L. fragrantissima 

 with small white fragrant flowers appearing before the 

 leaves which are very small and half evergreen. Loni- 

 cera trichosantha is a low shrub with slender spreading 

 and sometimes almost prostrate branches, light bluish 

 green leaves from one to two inches long and small yel- 

 lowish flowers followed by red berries. Lonicera pileata 

 and L. gijnochlamijdea have insignificant whitish flowers 

 followed by rather small red berries; the foliage of the 

 first species is nearly evergreen and small, while the 

 second has large lanceolate leaves from two to four 

 inches long; both are probably tender. Three other 

 species, viz., L. deflexicalyx, L. leycesterioides and L. 

 Altmannii have already been mentioned and briefly 

 described in the issue of June 26. and as another spe- 

 cies new to cultivation and allied to the last named may 

 added here L. Olgae from Turkestan with small bluish 

 green ovate leaves and small white flowers. 



As one of the handsomest and most graceful in its 

 fruiting state of the Hollies with deciduous leaves must 

 be considered Ilex grnicuhita from Japan whieh is new 

 to cultivation and fruited last year for the first time 

 profusely at the Arboretum. It is a slender-branched 

 shrub with ovate-oblong leaves about two inches long 

 and pea-sized crimson fruits borne in twos or threes or 

 solitary on thread-like pendulous stalks about one inch 

 long : they ripen in August and last until the end of 

 October when the leaves turn yellow. Like other Hol- 

 lies the species is dioecious and it is therefore necessary 

 to plant staminate together with pistillate plants to 

 insure profuse fruiting. 



Sabbatia chloroides 



In August this charming bright pink sabbatia is 

 noticeable in the flowci- shops of Philadelphia. It is 

 indigenous to the light soils of the Xew Jersey pine 

 barrens, principally on tlie margins of ponds or streams. 

 A few thousands planted in your home grounds in a 

 similar situation, and in light, sweet soil, will give a 

 good account of themselves. The flower reminds one 

 of a miniature pink cosmos, and is delicately fragrant. 

 One of the important features that should be carefully 

 noted on this suliject as a cut flower is that every one 

 of the unopened buds shown in the illustration opens 

 out nicely in water. Excellent as a cut flower. Hab- 

 itat: Atlantic States, Massachusetts to Florida. Can 

 be procured from Dreer, or any of the hardv plant 

 dealers advertising in HoiiTicuLTURE. 



The Propagation of the Phlox 



NOTES FROM THE YORK, XKIiliASICA, EXPERIMENT STATION 



For some years we have been engaged in originating 

 new and hardy varieties. First, we want flowers of 

 superior beauty. Second, we should have a fine head, 

 large and symmetrical. Many phloxes lack this. Third, 

 we must have a plant that wall endure continuous wet 

 weather without rusting and blighting. At least one- 

 half of the imported ones are worthless in tliis respect. 

 Fourth, we want those tliat can endure the terrible heat 

 of our western plains. Etna, Coquelicot and LcMahdi
