ROCK GARDENS 



Flowers, borne in terminal racemes, are of a bright golden -yellow. 

 It is a pretty plant, but not nearly so good as H. reptans^ with which 

 it must not be confused. 



H. reptans. — Forms a close mat, some 2 inches high, of long, 

 trailing stems. Small leaves and large golden-yellow flowers in the 

 greatest profusion from July to October. A very quick grower. 

 There is no better plant for covering a rock. Second only to 

 H. fragilis in value and beauty, and by some, in fact, considered 

 better. 



The above represent the best traihng kinds. The following are 

 the choicest of the shrubby type : — H. cegyptiacum^ balearicum^ 

 olympicum^ Hookeriamini^ and inoserianum. 



Iberidella rotundifolia (Cruciferae) 

 A charming little plant, found at very high altitudes in the Alps. 

 It requires light shingly loam, well drained, and makes dense mats 

 only about 3 inches high. The glaucous, olive-green leaves are 

 thick and leathery. The flowers are bright rosy-lilac, and sweet- 

 scented. They are borne in some profusion from April to June. A 

 very delightful little plant, of easy culture, and coming freely from 

 seed. It should be grown among the choicest rock plants, and 

 should find a place in every garden. 



Iberis (Cruciferae), Candytuft 



A genus of evergreen, dwarf-growing plants, of the easiest culture 

 in any Hght loamy soil, in an open situation. With one or two 

 exceptions, they are all quite hardy. Propagated by seeds, division, 

 or cuttings. 



/. correaefolia. — Grows about 12 inches high, making quite a 

 shrubby little plant. Compact, flat heads of large, pure white 

 flowers. It blooms rather later than the other kinds, not coming into 

 flower until about the beginning of June. Of free and vigorous 

 growth, and easily increased by seed or cuttings. It is one of the 

 best. 



/. gibraltarica. — A somewhat straggling-growing plant of some 

 12 inches high, with larger flowers and leaves than the other kinds. 

 The flowers, which are very freely produced, are borne in close 

 heads and of a rosy-lilac colour. It blooms about May. Not very 

 hardy, and, except in a favoured climate, should be protected during 

 the winter. Easily propagated by cuttings. A most attractive 

 plant, which is well worth taking some trouble about. 



/. petraea. — Of very dwarf and prostrate habit, and a great pro- 

 fusion of white flowers. Very pretty species, of fairly easy culture 

 in good loam. It is given by some as a variety of /. Tenoreana.
