CASSELL'S POPULAE GAEDEXIXG. 



flowers, having "been a favourite in English gardens 

 for at least three hundred years. The less often 

 they are disturbed, the finer and larger wiU they 

 grow. Propagated hy division. Native of Southern 

 Europe. 



Roustonia coendea (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 Xorth America. 



Hutchinsia alpina (Alpine Hutchinsia). — Another 

 very dwarf Alpine. In suitable positions it grows 

 into dense compact plants, and produces masses of 

 pure white flowers. Soil weU drained, with sand 

 preponderating. Propagated by division. A native 

 of Southern Europe. 



* Ihcris corifolia (Coris-leaved Candji;uft). — An 

 evergreen Candytuft, dwarf in growth, bearing a pro- 

 fusion of white flowers during ]\Iay. "WiU grow in 

 any position and soil. Propagated by division and 

 cuttings. Native of Sicily. 



* Iberis correcefolla (Correa-leaved Candytuft). — 

 This is now generally regarded as a garden hybrid 

 of the common peri nnial 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 evergi'een, 

 and is cheerful-looking all the year round. Any 

 ordinary gardt-n 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 ^^dll yield an abundance 

 of plants. Native of the Alps and Pyrenees. 



* Lmaria Ci/atbalaria (Ivy Toadflax).— A pretty 

 native plant often foimd on rocks, old walls, and 

 stony places. Easily raised from 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 Z. C. 

 alba. 



Zinncea borealls (Twin-flowtr). — A small trailing 

 evergreen, a member of the Honeysuckle family, 

 found gTOwing ^dld in som*^ 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 moistirre 

 will be always available, consequently on the rockj." 

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

 Increased by di^ision. 



^Linton rdpinum (Alpine Flax). — The flowers are 

 dark blue in colour, and appear in Juh' and August. 



Soil, good peaty loam. Situation, warm and well 

 di-ained. Propagated by seeds, divisions, and cut- 

 tings in spring. A native of many parts of 

 Eui-ope. 



* 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 evergxeen. It should be allowed room to 

 spread flatly, or to depend down the face of a rock, if 

 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 eri'oneously, called L. fraticosioii. Native 

 of Spain and Southern France. 



Lychnis Lagascm (Rosy Lychnis). — One of those 

 dwarf Alpiae 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 

 best adapted for it is an exposed one where, between 

 two projecting stones, it wlQ obtain a little pro- 

 tection, and the beauty of the flowers will justify its 

 being placed in a most prominent position. Soil, 

 if well intermingled with grit or sand, may be of 

 any kind. Readily inci eased from seeds. A native 

 of the Pp-enees. 



* Lysimachia Xtannitdaria (Creeping Jenny). — Al- 

 though this is a common native plant, there are few 

 rockeries from which it will 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. Tlie flowers are of a pleasing 

 yellow, and are produced profusely. There is a 

 golden-leaved variety which is almost better than 

 the t^^pe. This is one of the accommodating plants 

 which will grow as well on the window-siU. of 

 a back coui't 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 year, 



* Me?iziesia 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.
