THE ROCK-WALL IN SUN 23 



warmth-loving genus ; and in the grey part of the 

 wall there will be Southernwood and Catmint {Nepeta 

 Mussini), Hyssop and Lavender Cotton, and the 

 curious, almost blue-leaved, Othonnopsis cheirifolia. 

 Many of these will be among the plants just named, 

 but to make this clear and easy for reference they 

 will be put together in the list at the end of the 

 chapter. 



The hardy Fuchsias will also be good plants for 

 the head and foot of the wall, and the pretty little 

 F.pumila for the wall itself. 



There are two of the small St. John's-worts that 

 must not be forgotten, Hypericum coris, a perfect gem 

 among dwarfer shrub-like plants, and H. rcpens, its 

 exact opposite in habit, for H. coris stands up erect, 

 and H. repeats hangs straight down like Moneywort in 

 a window-box. 



It would be tempting in Cornwall to try the Caper 

 plant {Capparis spinosd) and the hardier of the 

 Mesembryanthemums that do so well in the Scilly 

 Islands ; the best to try would be M. blandum in its 

 two varieties — album and roseum, seldom entirely out 

 of bloom ; the straw-coloured M. edule and its hand- 

 some crimson-flowered ally, M. rubro-cinctum ; M. 

 glaucum, one of the hardiest and finest, with large 

 canary-yellow flowers ; and M. deltoides, which forms 

 a dense curtain when it is allowed to hang, and fills 

 the air in spring with the vanilla-like scent of its small 

 but countless pink blossoms. 



With these, and in a part of the wall specially pre- 

 pared with rather larger spaces between the stones in
