GENERAL REMARKS. 



place in the rock-garden, 

 or at the margins of 

 evergreen or deciduous 

 shrubs. T. sessile, T. 

 californicum, T. erectum, 

 and one or two others 

 are good too, but none 

 approach grandiflorum. 



The Trolliuses, or Globe 

 flowers, are charming 

 early-flowering perennials. 

 They like moisture and 

 rich soil. You cannot do 

 better than have the rich 

 yellow T. napellifolius, 

 deep orange T. Fortunei 

 (japonicus fl. pi.), golden- 

 coloured Asiaticus, and 

 a variety called Orange 

 Globe. 



A pretty trailing plant ; not 

 always happy in gardens. 

 The leaves are greyish ; 

 flowers yellow in long 

 trails. 



Every enthusiastic amateur 

 almost tries to establish 

 this Tropseolum, but it is 

 fickle. This is the climber 

 that covers many a High-

 is important. Put the 

 roots half a foot deep, 

 and do not disturb them. 



This is a flower of winter, 

 with nutty perfume, and 

 grows in ordinary soils. 

 Only of value for its per- 

 fume and winter flower- 

 ing. 



Very useful bold plants for 

 the wild garden. 



The Veronicas are a pretty 

 family. V. subsessilis, 

 which is about 3 feet 

 high, is one of the most 

 important : its flowers are 

 blue. V. rupestris and 

 V. -repens are creeping, 

 and form quite a green 

 mat, covered respectively 

 with blue and white 

 flowers in summer. V. 

 incana is welcome for its
