10 A Retrospective View of the Progress of 



plants have been Henfreya scandens, Plumbago Larpentec, 

 Adamm cyanea, Hindsia longiflora and violacea, Tropae^o- 

 lum Ijohbiamwi (very beautiful), Gloxinm Teuchlen, Scu- 

 tellaria Ventenat2, Fuchsm spectabile, Gardenia Fortune, 

 Zauschneria californica, Heliotrope Souvenir de Liege, Rob- 

 inson's Defiance Verbena, &c. The principal additions of 

 new plants are now made through the exertions of the col- 

 lectors of the London nurserymen, maintained at their own 

 expense. 



We should not, perhaps, omit to mention the hollyhock, 

 which is now, and justly, attracting so much attention abroad. 

 As a showy border-flower for large gardens it is especially 

 suited ; and, now that so many beautiful and distinct seed- 

 lings . have been produced, they demand a place even in a 

 very limited collection. During the last year or two, the 

 English gardeners have commenced giving names to some of 

 their choicest seedlings, so that they may be perpetuated by 

 propagation. The Massachusetts Horticultural Society have 

 enhanced the prizes for this flower the present year ; and this, 

 we trust, will lead to greater competition, and, in the end, to 

 the production of very much improved varieties. Some ex- 

 cellent hints on their propagation, &c., will be found at p. 555. 



ARB ORICULTURE . 



The taste for ornamental planting, and the desire to pos- 

 sess the new and fine kinds of the Coniferas, is rapidly 

 increasing, and the catalogues of our nurserymen now in- 

 clude many of the best species and varieties which are likely 

 to prove hardy in our climate. We have copied much informa- 

 tion on this head from our foreign papers, and the amateur 

 planter will find the different papers worthy of careful peru- 

 sal. We have also noted some of the Pinuses which have 

 already proved hardy here, and we shall continue to add to 

 the list all which succeed as far north as latitude 42°. Ce- 

 drus Deodara proved perfectly hardy, the last severe winter, 

 without the least protection ; and we have no doubt, if the 

 location is favorable, it will prove as hardy as our native 

 hemlock. Abies Smith«awa is a fine hardy species ; as is
