JOUENAL OP HOBTICULTURE AND COTTAGE GARDENEB. 



[ October 31, 1865. 



may some day be employed as an edging to beds, as wdl as for 

 the tipper parts of roekwork. Sandy loam. 



Adekietia deltoidea, and its variety gi'andiflora, cover rock- 

 Work, both in Sim and in shade, and bloom nearly all the 

 year round. 



Arenaeia c.espitosa, cekastifolia, and ealearica, the last 

 being a tiny creeper upon rocks, and having multitudes of 

 little white flowers, need very gritty soil, with just water 

 enough to keep it moist. 



Anemones are numerous. One of the best is A. apennina, 

 sky blue, grows anywhere if it has plenty of loam and leaf soil. 

 A. ranunculoides is a Wood Anemone, with yeUow flowers. 

 The double white (A. nemorosa plena), and double red (A. ne- 

 morosa rubra plena), are indispensable for shady fissures filled 

 with r eh loam and leaf mould. A. sylvestris has white flowers 

 early in summer, but A. alpiuais the most stately of the white- 

 fiowering kinds, and succeeds well in deep sunny fissures. 

 A. coronaria, or the garden Anemone, affords a great variety of 

 brilliant colours. Among others of the same family, I must 

 name A. stellata or hortensis, with rosy purple flowers ; A. pal- 

 mata, with Cyclamen -like leaves, and golden yellow flowers; 

 and A. sulphurea, with lemon -coloured flowers, and which 

 requires grit and stone along with the loam, and sunny, sloping 

 banks. 



Aenica MONTANA, flowers orange yeUow ; solitary. 



AzAiEA THocuMBENS, delights in sun, and moist gritty peat 

 soU. 



Arabis lucida variegata, is neat for sunny fissm-es, and 

 A. caucasica variegata, is nearly as free as A. albida and alpina. 

 Mowers white. 



Aster alpincs, flowers large and solitary, lilac purple. There 

 is a white variety. 



Aonii.EiiiA ALPINA, a charming Columbine for shady fissures 

 containing turfy loam, moist, but well di'ained. The flowers 

 are purplish blue with a white centre. 



Aretia vitaliana, forms a carpet of yellow bloom, and like 

 Audrosace, requires moist grit in sunny fissures. 



Andeos.vce. — This genus gives us A. carnea with Saxifrage- 

 like foliage, and rose-coloured flowers, with a yellow eye ; 

 A. lanuginosa, silvery trailing foliage, flowers lilac and white, in 

 umbels; A. ciliata, rose colom-; A. eoronopifolia, white; and 

 A. chama?jasme, white, with yellow eye. All succeed in sunny 

 fissures under overhanging rocks. Moist grit with a little peat. 

 They should be kept moist by filtration from above without 

 wetting the foliage, especially in winter. 



Beyanthds eeectus, a little evergreen shrub with pink 

 flower-, by some said to be a natural hybrid between Ehodo- 

 dendrcn chamajcistus and Kalmia glauca. Moist peat and grit, 

 and a sunny exposure. 



Bellis peeennis AnccB.EEOLiA, the finest of the Daisies for 

 the lower parts of rock ; moist loam. 



Campanulas. — No plant is more effective on rock than 

 C. garganica, from its pendant habit and sheets of lilac flowers. 

 C. mui'alis, C. pulla, difficult to obtain true, G. hederacea, and 

 C. alpina, succeed in simny fissures in sandy loam. 



Cerasticm tomentoscm and C. Biebersteini are well known 

 as edging plants, and never look so well as on rockwork. 



C. ALriNU5i is by no means so easy to grow as the two pre- 

 ceding. It forms dense, prostrate, silvery tufts, and is im- 

 patient of wet on the foliage. Peat, loam, and grit, kept moist. 



Carex nigra is suitable for the base of roekwork, where the 

 roots can reach water, being best on the margin of such. 



CocHLEAKLi GRiEXLANDicA needs peat and loam, with grit, 

 kept wet. 



Cheiranthus ALPiNtrs, a lovely bright, dwarf, yellow 'Wall- 

 flower, doing best in sunny fissures fiUed with loam and sand- 

 stone. C. Marshalli is well known for its dwarf habit and 

 orange flowers. 



CoLCHicuM ALPiNrM, rosy-purple flowers in autumn and 

 winter ; of dwarf habit ; slopes of deep loam. It is somewhat 

 rare. From the Alps. 



CisTcs. — I may enumerate the following species — viz., 

 C. formosus, yellow, with dark spot in the centre of each petal ; 

 C. algarvensis, yellow, with dark ring in the centre ; C. lusi- 

 tanicus, yellow ; C. albidus, whitish leaves and pale purplish 

 flowers ; C. salvifolius ; C. Ledon, and C. ladaniferus with 

 white flowers ; C. purpureus, C, creticus, purple; C. roseus, 

 rose-coloured. Tliey are somewhat tender, requiring sunny 

 slopes, and loam upon Umestone, or the last mixed with the soil. 



Daphne cneorum, trailing over rockwork when planted in 

 fissures in peat and loam, well drained. It does better on lime- 

 stone rock than on sandstone. Flowers pink, produced abun- 



dantly, and very sweet. D. mezereum autumnale is a fine 

 autumn Mezereon. Both for sunny exposures only. 



Cyclamen bepanddm, bright rose, blooming in spring. On 

 warm ledges or fissures only, well drained, nearly dry in winter, 

 and ha\-ing a rather shady exposure ; peat and loam with an 

 equal proportion of grit. The following require similar treat- 

 ment, and are beautiful for rockwork : — 



C. conn, red, blooming out of doors in February and March 

 unless prevented by frost. It need not be so dry in winter as 

 repandum. C. coum vemum has u'regular blotches of silver 

 on the leaves, and blooms later. 



C. eobop.eum blooms in summer and autumn, red, fragrant. 



C. ODORATUM. — I am inclined to question whether this is 

 more than a variety of the preceding. It has pale and almost 

 white flowers, having a delicate scent. 



C. NEAPOLiTANCM, or C. hederjEfolium, rose or pink, and its 

 white variety are beautiful, both in flowers and foliage ; the 

 flowers appear before the leaves. 



Crocus nudiflorus is an autumn purple-flowering species, 

 for deep fissures of rich loam. C. nivalis or Sieberi is a light 

 violet-flowering autumn and winter species. 



CoRONiLLA glauca, ycllow, in warm situations in sun, and in 

 fissures of loam well drained. C. varia and C. corouata will 

 be found useful yellow-flowering imder-shrubs or shrub-hke 

 plants. 



Cornus CANADENSIS, a Dogwood for moist well-diained peat 

 and grit. 



Convolvulus sepium eoseus, rose-coloured variety of the 

 white wild Convolvulus. Planted in loam in simny exposures 

 it runs over rocks, and is quite a novel and charming feature. 

 The white Convolvulus, so common and troublesome a weed, 

 is indeed charming for a hke purpose. 



DiANTnrs ALPiNos, very dwarf, rose-coloured flowers pro- 

 duced in great profusion ; peat, loam, and grit in deep simny 

 fissures, kept wet, but well drained. D. deltoides, D. floribun- 

 dus, fringed pink flowers ; D. fragrans, like the last, fringed, 

 but with white flowers, and very sweet. The varieties of 

 D. Heddewigii do well in sunny situations. 



Draba aizoides, dwarf, yellow ; flowers in a sunny part of 

 the rockwork in spring ; loam and grit. D. boeotica is very Like 



D. aizoides, but paler in colour. 



Dryas Drubimondi, a trailer mth sulphur flowers. D. octo- 

 petala, fine pendant evergreen foliage, and creamy-white 

 flowers ; moist peat and limestone fissures. 



Eriasthus Eavexn.e, a very ornamental and stately Grass; 

 sand and loam kept wet. 



Erinus alpinus, a beautiful plant for old walls ; flowers rosy 

 purple ; its variety, roseus, is dwarfer and has larger flowers of 

 a rosy pink. 



Erigeron speciosus, flowers purple with a yellow disc, of 

 long continuance. E. graudiflorus has Hlac flowers with a 

 yellow centre ; sandy loam. 



Ericas vulgaris, Hammondi, rigida variabilis, variegata, de- 

 cumbens, and Alporti ; carnea ; E. tetralix alba and rubra ; 



E. scoparia and nana ; E. cinerea alba, and varieties rosea, 

 rubra, and atropurpurea ; E. stricta ciliaris ; E. mediterranea ; 

 E. herbacea and its variety carnea; E. vagans alba, carnea, 

 and rubra, are what I have had in fissures and slopes of rock in 

 peat and grit, and they are alike ornamental in foliage and 

 bloom, which varies in colour from white to deep rosy scarlet. 

 In summer they should not be allowed to dry up for want of 

 moisture ; they rarely do so after they become established, but 

 are apt to suffer for a year or two. 



Eryngium maritimcm, a dwarf Holly-like plant, with silvery 

 leaves ; plenty of moisture and deep light loam and stones are 

 essential. E. alpinum had large and showy bluish involucres ; 

 sand and loam. 



Eriophorum alpinum, or Alpuie Cotton Grass, has small 

 cottony heads, and forms a dense dwarf turft ; wet peat and 

 grit on ledges. 



Euphoeeia portlandica, for hot sunny fissures only, where 

 the leaves and stems become scarlet ; sand without any ad- 

 dition. 



Genista peocumbens, prostrata, triquetra, and sagittalis, 

 excellent yellow-flowering under-shrubs ; sandy loam and peat. 



Geranium argenteom, a sUvery-leaved hardy Geranium. 

 I have notions in respect to it as a bedding plant ; rare or little 

 known ; habit dwarf and prostrate ; flowers white or blush, 

 veined with purjile. G. sanguineum and lancastriense are 

 well-known British plants. 



Glechoma HEBER^icEA FOLiis VARiEoATis, handsomB, Creeping 

 over rocks and running in fissures kept moist ; loam.
