ALPINE FLOWERS FOR GARDENS 



239 



in France and Switzerland, and these 

 varieties have been given fine names ; 

 but, to some extent, they are repetitions 

 of each other, and it is not worth while 

 being very particular as to whether they 

 are named or not, if we have kinds that 

 please us in colour. 



HELONIAS BULLATA (Stud 

 Flower}. A distinct and handsome 

 marsh perennial, growing 12 inches 

 to 16 inches high, and having hand- 

 some purplish-rose flowers arranged 

 in an oval spike. It is suitable for 

 the artificial bog, or for moist ground 

 near a rivulet. In fine sandy and 

 very moist soils it thrives well as a 

 border plant. North America. Syn., 

 H. latifolia. 



HEMIPHRAGMA HETERO- 

 PHYLLA. A dwarf trailing plant of 

 the Figwort family, bearing incon- 

 spicuous flowers, succeeded by bright 

 red berries about the size of small 

 Peas, on slender creeping stems. It 

 is rather tender, and requires a 

 sheltered and well-drained spot in the 

 rock-garden. Himalaya. 



HEPATICA. (See ANEMONE.) 



HERNIARIA. Dwarf trailing per- 

 ennial plants, forming a dense turfy 

 mass that remains green throughout 

 the year. There are two or three 

 species, but the most important is 

 H. glabra, useful on account of its 

 dwarf compact growth, and is always 

 of a deep green, even in a hot and 

 dry season. They grow in any soil, 

 but the flowers are inconspicuous. 



HESPEROCHIRON PUMILUS. 



A pretty Californian rock plant, stem- 

 less, dwarf in growth, with leaves 

 borne on slender stalks, forming a 

 tuft, the flower bell-shaped, half -inch 

 across, white, varying to a purplish 



tinge. It grows in marshy ground, 

 and in damp places in the Rocky 

 Mountains and Northern Utah, and 

 is apparently quite hardy, as it thrives 

 in ordinary soil in well-drained parts 

 of the rock-garden. H. californicus 

 is a species of somewhat the same 

 habit. 



HIERACIUM (Hawkweed).Avery 

 extensive genus of Composites, con- 

 sisting chiefly of perennial herbs with 

 yellow flowers. Some of the yellow 

 alpine and other kinds are valuable 

 in botanical collections, and many of 

 them are beautiful, but the prevalence 

 of yellow flowers of the same type 

 makes them less important, and not 

 a few are too large and coarse for the 

 rock-garden. 



HIPPOCREPIS COMOSA (Horse- 

 shoe Vetch). A small prostrate British 

 plant, with pretty little deep-yellow 

 flowers, in coronilla-like crowns, the 



Zper petal faintly veined with brown, 

 3 pinnate leaves small, and leaflets 

 smooth. It is a capital little plant 

 for the upper ledges of rocks in dry 

 positions, as in such places the shoots 

 will fall down some 18 or 20 inches ; 

 easily raised from seed; partial to 

 chalky soils; rather common in the 

 South of England, but not a native 

 of Ireland or Scotland. 



HORMINUM PYRENAICUM. A 



Pyrenean plant, forming dense tufts 

 of foliage and having purplish-blue 

 flowers, in spikes about 9 inches high, 

 which appear in July or August. It 

 is hardy and of easy culture, but is 

 not a plant of much character from 

 a garden point of view. 



HOTTONIA PALUSTRIS (Water 

 Violet). A beautiful British water- 

 plant, which I include here in conse-
