ROCK GARDEN PLANTS 37 



for a garden of moderate dimensions ; in one of large 

 size it would be better to adopt bolder grouping with 

 the same plants, rather than make additional space an 

 excuse for the inclusion of inferior kinds. 



ROCK GARDEN PLANTS 



Acxna. Dwarf plants for carpeting. Only the New 

 Zealand variety (A. microphylla) should be grown, and 

 that for the sake of its crimson spines. 



Achlllea. The best of the rock garden kinds are 

 umbellata, with silver foliage and white flowers, and 

 tomentosa, bright yellow. A fairly dry soil suits 

 them best. 



Adonis. Pheasant's Eye. A very precious plant. A. 

 vernalis(Ox-Eye), forms dense clumps of fern-like foliage, 

 from which rise large yellow flowers. It blooms in spring, 

 and is suited to a good loamy soil. Division or seeds. 



JEthionema. An Alpine sub-shrub. A. grandiflorum, 

 forms dense spreading masses of foliage, covered with 

 stout racemes of rosy flowers. Owing to its prostrate 

 habit it is useful for mantling the edges of rocks. Well 

 drained loam. Seeds. This is quite one of the loveliest 

 of Alpine plants. 



Alyssum. Madwort. A charming spring flower, 

 rejoicing in the fullest exposure. A. saxatile (Gold 

 Dust) with its brilliant corymbs, blooms in autumn 

 as well as spring. 



Androsace. Described elsewhere. The best kinds 

 are : A. carnea, glacialis, and helvetica. 



Anemone. Wind-flower. A. apennina, A. blanda, 

 A. Pulsatilla. See chapters on Bulbous Plants and 

 Alpines. 



Antennaria. Cat's Ear. Dwarf plants, of which A. 

 tomentosa forms a silver carpet of foliage. A. dioica, 

 with pink flowers, is worth growing. Simple culture.
