98 THE BOOK OF CLIMBING PLANTS 



grafting the varieties on the roots of free-growing 

 species, such as Flammula, in heat as early in the year 

 as possible. The roots are lifted from the open ground, 

 cut into pieces, split open, and the scions (of the 

 young shoots) inserted and tied in position with matting 

 or raffia. Place these in small pots, and plunge in a 

 warm, moist propagating frame until the scion and 

 roots unite, when they may be hardened off. Layering 

 is the simplest method for the amateur who may only 

 require a plant or two. Layers take about a year to 

 root in the open ground ; they can then be separated 

 from the parent plant. Cuttings of the young shoots, 

 with one or two eyes, can be struck in heat in small 

 pots of light soil in a propagating frame. Seeds are 

 a suitable means of propagation for some of the species, 

 but the varieties of others are not to be relied upon 

 to be equal to the parents. Such species as Flammula, 

 Vitalba, or orientalis grow readily from seeds and the 

 last will bloom in the first or second year. Sow in 

 sandy soil in spring in moderate heat, giving air when 

 the seedlings are up, and pricking out into single pots 

 when large enough. 



The Clematis under Glass 



There are few prettier climbers for growing under 

 glass than the large-flowered hybrid Clematises, both 

 the single and double flowered varieties being admirably 

 suited for the rafters or walls, while the whole of 

 these large-flowered varieties are highly ornamental 

 if grown on trellises, either in pots or planted out. 

 The soil suitable for the outdoor plants will answer 

 well, and no special care beyond careful training and 

 the destruction of green fly and other pests will be 

 required. A temperature not much higher than 40 

 to 50 degrees is very answerable for these Clematises.
