234 ALPINE FLOWERS AND ROCK GARDENS. 



it called monstrosa, and one with pink flowers called 

 rosea. The species prostratUy which has white flowers 

 in summer, is also suitable for the rockery. 



HABERLEA RHODOPENSIS,—A pretty plant, 

 somewhat resembling the Pyrenean Violet (Ramondia) 

 v^dth pale lilac flowers in spring. The plant grows in 

 dense tufts, and the flower stems are only an inch or 

 two high, so that it is quite a rockery gem. It Hkes 

 peat, and may be given a position between stones 

 where it is not exposed to the full sun. It may be 

 raised from seed in spring, or increased by division 

 in late winter. 



HELIANTHEMUMS (Sun Roses).— These tough 

 and wiry little shrubs enjoy considerable favour with 

 rock gardeners, because they will thrive in dry places, 

 and bear brightly coloured flowers with much diversity 

 of hue. They are evergreens, and possess a tenacity 

 of life which enables them to exist in hot, sandy soils 

 where most plants would perish. There are very few 

 species, but there are a large number of forms of the 

 common yellow trailing species vulgare, both single 

 and double, all having the habit and taste of their 

 parent, and only differing in colour and form of flower. 

 They are somewhat too vigorous for the small, select 

 rockery. The Sun Roses may be raised from seed 

 sown out of doors late in Spring. 



HEPATICA. — Referred to in its proper genus 

 Anemone. 



HERN I ARIA GLABRA,— A useful carpeting 

 plant, forming a dense mass of vivid green. The 

 flowers are of no importance, but the plant is worth
