regime that it so readily succumbs to mildew. A little flowers 

 of sulphur should always be near to the hand of the Verbena 

 grower. 



GREENHOUSE CUMBERS 



Greenhouse Climbers embrace a considerable variety of sub- 

 jects, the greater part of which respond to identical treatment. 

 Most of them are propagated from cuttings, some few from seeds, 

 the demand for them being consistently steady. It is sometimes 

 difficult to draw the line between greenhouse and hardy Climbers, 

 some of the former thriving in the open air down south and some 

 of the latter finding frequent use in greenhouses, especially 

 farther north. But we should rule the following representative 

 plants as belonging to the different sections : 



HARDY CUMBERS. GREENHOUSE CUMBERS. 



Ampelopsis. Abutilons. 



Aristolochias. Cobeas. 



Bignonias. Eccremocarpus. 



Clematis. Habrothamnus. 



Honeysuckles. Hoy as. 



Ivies. Tacsonias. 



Jasmines. Plumbagos. 



Passifloras. Pereskia. 

 Polygonums. 

 Wistarias. 



We leave out such stove climbers as Allamandas, Clerodendrons, 

 Gloriosas, Stephanotis, etc., because the trade in these cannot 

 be called a market trade, being done entirely retail by the 

 general nurserymen. We therefore confine our remarks to 

 legitimate greenhouse climbers. 



Eccremocarpus Scaber and Plumbago Capensis are easily 

 raised from seeds, and where seedlings are as reliable as cuttings 

 and give less trouble, we give the preference to them. When 

 we want Cobea Scandens we resort to seeds, but for Cobea S. 

 Variegata we must perforce fall back on cuttings. Hoyas, 

 Habrothamnus, Abutilons, Tacsonias, and Pereskias are all 

 grown from cuttings, the latter being grown chiefly as a stock 

 for Epiphyllums. Perhaps we ought to include the Passion 

 Flowers here, as it is more often grown through all its earlier 

 stages in the greenhouse.
