EASILY GROWN ROCK PLANTS QI 
larias, Uvularia grandiflora, Colchicums, and many other 
flowers that grow up in individual manner rather than in 
a mass, reveal their charms to the full when the ground 
between them is carpeted with the close growing greenery 
of such plants as Herniaria glabra; and if the yellow 
leaved variety H. glabra aurea is used under the purple 
Orchis or Colchicums, the colour effects are still more 
pleasing. The WHerniarias are not particularly showy, 
but they will grow without difficulty, covering neatly any 
odd slope and corners that might otherwise be bare of 
verdure, and they are small enough to serve the purpose 
indicated above without smothering the more important 
plants between which they grow. H. incana is whitish 
grey, and dark-coloured flowers look well over it. 
HIPPOCREPIS COMOSA.—This is a native plant of con- 
siderable charm. Its stems snug the ground, and are 
closely covered with pinnate leaves. The flowers are 
bright yellow, borne in clusters, the flowering period 
extending from May to August. 
HomoGynE.—For damp, shady places, in somewhat 
enclosed corners of town gardens, Homogyne alpina is 
quite a useful plant. Its foliage is of a glossy green, is 
maintained throughout the year, and from the end of 
March to May cheery rosy mauve flowers are borne on 
3 or 4 inch stems. H. discolour has flowers of purple 
and white, a little taller in growth than alpina. The 
plants divide with ease. 
HyPEericuM.—This is a wonderful genus, widely varying 
in size and character, and well worthy of close study. 
We have Hypericums that make big, strong growing
