550 ERYNGIUM. 



THE ENGLISH FLOWER GARDEN. 



ERYSIMUM. 



charming little groups. It can be in- 

 creased by division, and easily raised 

 from seed. It flowers during July and 

 August, and is a native of Dalmatia and 

 Croatia. 



E. giganteum (Giant Sea Holly}. 

 This does well in almost all positions and 

 varieties of soil. The large flower-heads 

 are excellent for winter decoration ; and 

 although not highly coloured like those of 

 many of the others, they make pretty 

 bouquets arranged with Grasses. It is 

 an excellent plant for grouping, and in 



The Amethyst Sea Holly (E. amethystinuin). 



large masses it forms a very picturesque 

 object, growing from 3 ft. to 4 ft. high, 

 with stout stems and deeply-lobed, spiny, 

 glaucous leaves. The involucre, of eight 

 to nine large, oval, spiny leaves, pale grey 

 or glaucous, is very effective. Caucasian 

 Alps and Armenia. 



E. maritimum (Common Sea Holly}. 

 This plant is found growing along the 

 coast in company with the Oyster plant 

 (Mertensia maritima) and is a very pretty 

 kind, requiring no special culture, and 

 does well in a stiff, loamy soil. It is one 



of the most glaucous of the species, flower- 

 ing from July to October, and grows from 6 

 inches to i^ feet high. 



E. Oliverianuin (Olivers Sea Holly}. 

 This is of easy cultivation, and the abun- 

 I dance of its highly coloured flower-heads 

 renders it very attractive in the flower 

 border. It has often been, and is even 

 yet, confounded with the Amethyst Sea 

 ! Holly. E. Oliverianuin grows 2 feet to 

 3 feet and often 4 feet in height. The ten 

 i to twelve bracts composing the involucre 

 | are longer than the head of flowers and 

 have about half a dozen teeth on each 

 side. In habit and general appearance 

 it is more nearly allied to E. alpinum 

 than to any of the other kinds. It ripens 

 seed freely and in this way it may be 

 readily increased, and is a native of the 

 Levant. 



Other attractive kinds are E. Bourgati, 

 campestre, cceruleum, planum, of which 

 there is a very beautiful variety, dicho- 

 tomum, triquetrum, creticum, glaciale 

 spina-album. 



THE PANDANUS GROUP. To this 

 group, chiefly natives of Mexico and 

 Brazil, belongs some of the extraordinary 

 forms in this highly ornamental genus. 

 Beginning with Serra, we have a large 

 broad-leaved species with curious double 

 spines ; Carrierei, said to be the finest of 

 all, having a compact habit combined 

 with large, beautiful leaves. E. bromeliae- 

 folium is a charming plant, striking and 

 distinct in habit and forming elegant 

 Yucca-like tufts, with its graceful leaves 

 surmounted with whitish flower-heads. 

 E. pandanifolium is a noble plant, very 

 effective when grown as an isolated plant on 

 a lawn. E. Lasseauxi is nearly allied and 

 quite hardy in the open air. E. eburneum, 

 aquaticum, virginianum, Leaven worth i, 

 and others are all worthy of attention 

 for their fine foliage. D. D. 



ERYSIMUM. Wall-flower-like peren- 

 nials, biennials, and annuals, mostly of 

 dwarf growth. Of the perennials the 

 following are the finest : 



E. ochroleucum (Alpine Wallflower}. 

 -This handsome plant forms, under 

 cultivation, neat rich green tufts, 6 to 12 

 in. high, and in spring is covered with 

 beautiful sulphur-coloured flowers. The 

 rock-garden is most congenial to it ; but 

 it does very well on good level ground, 

 though it is apt to get naked about the 

 base, and may perish on heavy soils 

 during an unusually severe winter. It 

 thrives best when rather frequently 

 divided. Division and cuttings. A 

 capital dwarf border plant on light soils. 

 Alps and Pyrenees. Flowers in spring.
