MY GARDEN. 



is difficult to exterminate, and must on no account be admitted to the 

 alpinery. We have other varieties that are interesting. (See p. 343.) 



All these flowering plants are better grown in an intermediate 

 position, than at the top or at the bottom of the alpine mound, as 

 thus the roots are neither too dry nor too wet. 



The Draba bcotica (fig. 734) has somewhat the appearance of a 

 saxifrage, but its group of flowers is very dissimilar. 



FIG. 734. Dra.ba leotica. 



FIG. 735. Aubrietia Campbelli. 



FIG. 736. Dodecatheon Meadia. 



The Aubrietia Campbelli (fig. 735) is of a brighter hue than other 

 flowers of its genus. Its colour is violet blue, and it blossoms in 

 great profusion in March. 



The American Cowslip (Dodecatheon Meadia, fig. 736) should not 

 be omitted from our flowering alpine 

 plants. Its erect stem, crowned 

 with flowers, is dissimilar from other 

 plants. It is perennial, and only re- 

 quires to remain undisturbed. There 

 are varieties of this interesting 

 flower. 



FIG. 737. -Engeron spedosus. Then we have ErigeroH Roylei, 

 or spedosus (fig. 737), which is a handsome species 

 from the Himalayas; it has a yellow, disc-like flower, 

 with purple rays. 



The Genista sagittalis (fig. 738) produces abundance Fl&> Ja|i 

 of yellow flowers in summer, and is consequently a valuable 

 plant.
