ALPINES UNDER GLASS 



The cultivation of alpine plants in pans is a most attractive 

 form of gardening. Anyone with a small garden may grow 

 many interesting plants in this way, as the amount of accom- 

 modation required is not extensive, and the majority of the 

 commoner as well as most beautiful kinds are easy to grow. 

 Once potted up in suitable soil, many of the Saxifragas and 

 Sempervivums, to mention only two families out of a great 

 number, require little attention besides watering for two or 

 three years. In the case of bulbs, however, it is always 

 desirable to obtain a fresh supply each autumn. 



With the advantage of a small greenhouse without arti- 

 ficial heat in which to place the pans when the plants are 

 coming into flower their value is greatly enhanced, for then 

 one can enjoy their full beauty unimpaired by unfavourable 

 weather, to which they would be exposed if outside. A view 

 of such a house at Kew is shown in the illustrations, from a 

 photograph taken during the second week in March. This 

 house is unheated, and merely affords a shelter for the 

 plants while in flower. During the rest of the year they are 

 grown with the pans plunged to the rim in ashes in a 

 frame or sheltered border outside. The principal families 

 represented in flower are : 



Anemone ( Windflower\ This genus is represented by the 

 early flowering A. Blanda, from Asia Minor, with its lovely 

 dark blue flowers; A. Hepatica, with shades of red, white 

 and blue ; and the South European A. hortensis, with lilac 

 purple flowers, having a paler eye.
