THE FLOEAL WORLD AND GARDEN GUIDE. 9 



are truly wonderful ; yet how seldom are those hardy white flower- 

 ing plants seen in gardens ! Lathyrus latifoUus, superb to train up 

 over walls and arches in the full sun. Linarici cymhalaria* get a 

 bit of this to live on the front of a rough wall, and in due time it 

 will spread and become a feature in a garden, simple in the extreme 

 and lovely beyond description, and capable of taking care of itself 

 with the mere shadow of soil to live in. Lusimachia niimmularia, this 

 requires a body of soil, and is a gem amongst roots of trees. CEnofhera 

 riparia, this is a gem to plant amongst roots. PJilox alpimos, a 

 little gem for a ledge of rock, with a body of sandy soil to root in. 

 Fotcntilla fragariastrum, Primula acaulis, P. auricula, P.farinosa, 

 Fulmonaria Virginica, jRanuncidus alpestris, Sa^oonaria ocymoides, 

 slugs are very fond of this, but it is a rare beauty, ^axifraga 

 oppositifoJia, S. pulcliella, S. geranoides, S. cordifolia, S. liypnoides, 

 S. IceJandica, Silene acaulis, S. alpestris, S.petrcda, Spircea JlJipen- 

 dula, Statice latifolia, S. beUidifoIia, Thymus aziireus* T. lanuginosa, 

 T. officinalis, these are growing here in the face of the bastion, form- 

 ing large mats of beautiful vegetation. Trifolium incarnatuin, 

 Veronica spicata, V. saxatile,^ Vinca major, and V. minor, Viola 

 montana, V. cornuta ; the last are two gems for rockery banks. 



Yariegated-leayed Plants. — AJuga reptans fol. var., Arahis 

 alpinafol. var., A. luridafol. var., Aira ccespitosa fol. var.,* Aspidistra 

 liirida fol. var., Auhrietia deltoidea fol. var., FJialaris elegantissima,* 

 strange to say, this moisture-loving grass grows freely on the top of 

 the bastion, but much more luxuriantly on one of the sunny banks. 

 Mr. Salter has a rosy-tinted variety of it. Cerastium tomentosum 

 and C. Biehersteini, Cineraria maritima, Epilolium hirsutumfol. var., 

 Festuca glaucct,^ Fuchsia gracilis fol. var., Funkia ovata, F. Sieholdii, 

 Pulmonaria grandiflora fol. var., Spirea ulmaria fol. var. picta, 

 Trifolium repens fol. var., T. ruhrumpicium, Tussilago farfarafol. var.,* 

 Vinca major fol. elegantissa, V. major fol. reticulata, V. minor fol. var. 

 argentea. 



Succulents. — Sempervivur,i tectorum,* S. Californica,* 8. arach- 

 noides,* S. montanum.* A dozen more may be added, but these 

 four are pre-eminently useful. Seduni acre, S. glauca, S. anacamp- 

 seros, S. Faharium, S. Kamtschaticum, S. Sieholdii, this is quite 

 hardy, but the weather and the vermin usually spoil it when out of 

 doors. The Sedums like a moderate depth of soil, and though 

 essentially rock and wall plants, will not thrive on the pittance that 

 suffices for Sempervivums. Umhilicus horizontalis,* this pretty 

 plant requires a nice deep pocket, containing about a peck of sandy 

 peat, and occasional watering in dry weather, but in other respects 

 the more fully it is exposed the more finely will it grow. Mesem- 

 hrijanthemum clavellatum, M. criiciatum, M. licolor, M. falsiforme, 

 M. fiorihundum, M. glaucescens, M. inclaudens, M. maculatum, M. 

 roseum, M. salmonitum, M. violaceiim, M. umhcllatum. These twelve 

 are distinct and fine, but five or six dozen more may be added. One 

 of the best purposes this rockery has served me was in providing sites 

 for the display of a collection comprising 125 species, the greater 

 part of which unfortunately have been lost through want of care. 

 The best way to treat mesembryanthemums, when grown on ruins and
