IBERIS INULA. 



very dwarf and densely-cushioned. A 



native of Sicily. Borders, the 



rock-garden, or edgings, in ordinary 

 soil. Division, cuttings, or seed. 



Iberis correaefolia (Late White Iberis). 

 /. gibraltarica (Sort. ) /. coriacea, 

 The finest kind we have, more shrub- 

 like than /. saxatilis ; 6 to 15 in. high. 

 flowers, in May, later than the other 

 common evergreen Iberises ; large, 

 pure white, in close corymbs. Leaves, 

 oblong - spathulate, entire, almost 

 sessile, about 1 in. long and | in. 

 broad at the widest part, gradually 

 attenuated towards the stem. Seeds 

 produced very sparsely. This plant 

 is probably a hybrid, between 

 /. semperflorens and the Rock Iberis or 

 one of its forms, and was first distri- 

 buted from the Botanic Garden at 

 Bury St. Edmunds. One of the most 

 valuable of all plants for rockwork, 

 borders, or banks, growing freely in 

 any soil or position, but preferring 

 spots well exposed to sun and air. 

 Cuttings, seed, and division. 



Iberis gibraltarica (Gibraltar I.) 

 The largest, showiest and most strag- 

 gling kind, 1 to 2 ft. high. Flowers, 

 in early spring; large, white, often 

 suffused with red, in close heads. 

 Leaves, about 2 in. long, and 4 in. 

 wide, oblong-spoon-shaped, fleshy, 

 distinctly toothed at the top, slightly 



ciliated. Southern Spain. The 



rock-garden, borders, and banks, in 

 well-drained sandy loam. Seed or 

 cuttings. 



Iberis saxatilis (Rock Candytuft). 

 A small evergreen shrub, the com- 

 monest and one of the most useful of 

 the evergreen Candytufts ; 6 to 12 in. 

 high. Flowers, in spring or early 

 summer ; white, in corymbose heads. 

 Leaves, linear, entire, rather fleshy, 

 acute, ciliated. Native of Southern 



Europe. Borders, the rock-garden, 



edgings, and naturalization on rocky 



places or bare banks in any soil. 

 Division, seed, or cuttings. 



Iberis semperflorens (Window Candy- 

 tuft}. A fine kind, common in 

 Southern France and Italy ; 12 in. to 

 2 ft. high. Flowers, from October to 

 May ; very numerous, large, and of 

 a pure and dazzling white. Leaves, 

 broad, thick, spathulate, of a fine 



green colour. A native of Persia. 



It seldom seeds in this country, and 

 must be propagated by cuttings, for 

 which summer is the best time. Suc- 

 ceeds as a rock plant only in mild 

 parts, and in those near the sea. 

 I have seen it thrive well on the rock- 

 work in the College Botanic Garden at 

 Dublin, but our winters prevent it 

 from blooming as early as it does in 

 the south of Europe. 



Iberis Tenoreana (Tenor Js /.) A 

 showy species, resembling I. gibral- 

 tarica, but smaller, with rather fleshy, 

 toothed leaves, and ascending stems, 

 shrubby at the base ; 3 to 6 in. high. 

 Flowers,in early summer ; white, chang- 

 ing to purple, freely produced, in close 

 heads. Leaves, lower ones abovate, nar- 

 rowed at the base ; upper ones oblong- 

 linear, both leaves and stem hairy. This 

 plant does not survive our winters on 

 heavy soils, but is quite hardy on 



light well- drained ones. Naples. 



The rock-garden, or borders, in very 

 sandy dry soil. It is rarely healthy 

 or long-lived on clay. Seed. 



Inula Helenium (Elecampane"). A 

 vigorous native herb, with the lower 

 leaves a foot long, and 4 in. broad in 

 the middle, narrowing into a stalk ; 2 

 to 4 ft. high. Flowers, in summer; 

 yellow, in large solitary heads,- termi- 

 nating the branches ; rays linear, about 

 1| in. long, with three sharp teeth at 

 the end. Leaves,oi root oblong, stalked ; 

 of stem ovate or oblong, clasping, al- 

 most smooth above, clothed with soft 

 whitish hairs beneath ; those of invo- 

 lucre bluntly-ovate, downy; stem
