CASSELL'S POPULAH GAJIDENING. 



flowers, ha-vdng lieen a favourite in English gardens 

 for at least three hundred years. The less often 

 they are disturbed, the finer and larger will they 

 grow. Propagated by division. Native of Southern 

 Europe. 



Boustonia mrulea (Bluets).— A very dwarf plant 

 bearing an abundance of pale blue flowers. It 

 should never be grown except in connection with the 

 dwarfest Alpines, so that no risk may be incurred of 

 its being overrun by more vigorous-growing plants. 

 A moist peaty soil suits it best, in a position fully 

 exposed in chinks among stones. Propagated by 

 careful division. A native of North America. 



Suteh'msia alpina (Alpine Hutchinsia). — Another 

 very dwarf Alpine. In suitable positions it grows 

 into dense compact plants, and produces masses of 

 pure white flowers. Soil well drained, with sand 

 preponderating. Propagated by division. A native 

 of Southern Europe. 



* Iberis corifoUa (Coris-leaved Candytuft). — An 

 evergreen Candytuft, dwarf in growth, bearing a pro- 

 fusion of white flowers during May. WiU grow in 

 any position and soU. Propagated by division and 

 cuttings. Native of Sicily. 



* Iberis eorrecefolia (Correa-leaved Candytuft). — 

 This is now generally regarded as a garden hybrid 

 of the common perennial Candytuft. It is a very 

 distinct and most valuable plant, and bears fine 

 large white flowers in May and June. Deserves a 

 place on every rockery. The foliage is evergreen, 

 and is cheerful-looking all the year round. Any 

 ordinary garden soil suits it, and it seems to thrive 

 in every position. 



*Linaria alpina (Alpine Toadflax). — A little gem of 

 spreading habit and dwarf growth. Situation, moist 

 chinks of the rockwork, in sandy, gritty soil. Seeds 

 freely, and self-sown seeds 'will yield an abundance 

 of plants. Native of the Alps and Pyrenees. 



* Linaria Cymbalaria (Ivy Toadflax). — A pretty 

 native plant often found on rocks, old walls, and 

 stony places. Easily raised froin seeds. The posi- 

 tions where it grows naturally indicate those on the 

 artificial rockery where it will thrive best. Soil, 

 sandy peat. There is a pretty white variety L. 0. 

 alba. 



Zinneea borealia (Twin-flower). — A small trailing 

 evergreen, a member of the Honeysuckle family, 

 found growing wild in somfi parts of Scotland and, 

 though very rarely, in the North of England. The 

 flowers are pale pink in colour, and are produced in 

 pairs. Soil, sandy peat, in positions where moisture 

 will be always available, consequently on the rocky 

 portions of the bog-bed. Situation, somewhat shady. 

 Increased by division. 



* Linum alpinum (Alpine Flax).. — The flowers are 

 dark blue in colour, and appear in July and August. 



Soil, good peaty loam. Situation, warm and weU 

 drained. Propagated by seeds, divisions, and cut- 

 tings in spring. A native of many parts of 

 Europe. 



* Lithospermum prostratum (Prostrate Gromwell). 

 A delightfully beautiful plant, bearing a profusion 

 of Gentian-blue flowers during many months. Its 

 habit, as its name indicates, is prostrate, and the 

 leaves are evergreen. It should be allowed room to 

 spread flatly, or to depend down the face of a rook, i£ 

 it is wished to see it at its best. A moderately dry 

 situation in good loam suits it admirably, though it 

 will grow almost everywhere if the drainage is good. 

 It resents frequent removal. Situation, exposed 

 and sunny. Propagated by cuttings of last year's 

 growth, under a hand-light, in sand and peat or leaf- 

 mould, preferably in the summer. It is sometimes, 

 though erroneously, called Z. fruticosum. Native 

 of Spain and Southern France. 



Lychnis Lagascce (Rosy Lychnis). — One of those 

 dwarf Alpine gems that every lover of these charm- 

 ing plants will desire to possess. Its comparatively 

 large flowers are rose-coloured, and appear from 

 June to August. Its habit is very dwarf, so that it 

 must not be planted where its charms will be 

 obscured by plants of taller growth. The situation 

 b?st adapted for it is an exposed one where, between 

 two projecting stones, it will obtain a little pro- 

 tection, and the beauty of the flowers will justify its 

 being placed in a most prominent position. SoU, 

 if well intermingled with grit or sand, may be of 

 any kind. Eeadily increased from seeds. A native 

 of the Pyrenees. 



* Lysimachia NitmmulaHa (Creeping Jenny). — Al- 

 though this is a common native plant, there are few 

 rockeries from which it wiU be excluded. Its growth 

 is prostrate, and no situation suits it better than a 

 chink between two rocks, from whence it can depend 

 in graceful elegance. The flowers are of a pleasing 

 yellow, and are produced profusely. There is a 

 golden-leaved variety which is almost better than 

 the type. This is one of the accommodating plants 

 which' wUl grow as well on the window-siU of 

 a, back court in the densest part of London as on 

 a rockery in the most salubrious garden. It is in 

 nowise particular as to soil, but if it has the chance 

 will prefer a shady, moist situation. Most easily 

 increased by division, which may be made at any 

 . time of the yeai". 



* Menzieaia empetriformis (Empetrum-like Men- 

 ziesia), or more correctly, Bryanthus empetriformis. — 

 A Heath-like plant of great beauty, and very dwarf. 

 Should be grown by every one. Soil, rather moist 

 sandy peat. Situation, fully exposed. The bell-like 

 flowers, produced in clusters, appear usually in early 

 summer. It came to us from North America.
