ALPINE FLOWERS FOR GARDENS 



[PART II. 



ing more than 3 or 4 inches high. 

 For brilliancy of colour there is 

 nothing to equal it in cultivation, 

 the flowers being of a dazzling 

 magenta crimson, yet soft and 

 refined. In the evenings and in 

 cloudy weather it shuts up, and 

 nothing is then seen but the tips of 

 the flowers. It does very well in 

 any fine sandy, peaty, or other open 

 earth, is a hardy perennial on dry 

 soils. It is easy to raise from 

 seed, either in the open air in 

 fine soil, or in pots. As it does 

 not like transplantation, except when 

 done very carefully, the best way 

 for those who wish to use it for 

 very neat and bright beds in the 

 summer flower-garden is to sow a 

 few grains in each small pot in 

 autumn, keep them in dry sunny 

 pits or frames during the winter, 

 and then turn the plants out without 

 much disturbance into the beds in 

 the end of April or beginning of May, 

 and it may also be treated as an 

 annual, sown in frames very early in 

 spring, associated with diminutive 

 plants. 



CALLA PALUSTRIS (Bog Arum). 

 A small trailing Arum, with pretty 

 white spathes, hardy, and, though 

 often grown in water, likes a moist 

 bog better. In a marsh or muddy 

 place, shaded or otherwise, it thrives, 

 and in a bog carpeted with the dark 

 green leaves of this plant the effect 

 is good, as its white flowers crop up 

 here and there along each running 

 shoot, just raised above the leaves. 

 Those having natural bogs would 

 find it an interesting plant to intro- 

 duce, while for moist spongy spots 

 near the rock-garden, or by the side 

 of a rill, it is worth a place. N. 

 Europe, and also abundant in cold 

 marshes in N. America, flowering in 



summer, and increasing rapidly by its 

 running stems. 



CALLUNA. (See ERICA). 



CALOPHACA WOLGARICA. A 



prostrate half-shrubby plant of the pea 

 flower order, with deep yellow flowers 

 in racemes in summer, and small 

 pinnate greyish leaves. A pretty rock 

 shrub, easily grown and best from seed. 

 Avoid grafted plants, and plant in full 

 sun. 



CALTHA (Marsh Marigold}. 

 Showy dwarf perennials of essential 

 use in the marsh-garden. The native 

 kind is so frequent in a wild state that 

 there is rarely need to give it a place, 

 except on the margin of water. Its 

 double varieties, however, are worth a 

 place in a moist rich border, or, like the 

 single form, by the water-side. There 

 is a double variety of the smaller 

 creeping C. radicans, about half the 

 size of the common plant. In addi- 

 tion to the common species, C. palus- 

 tris, and the rarer variety, C. radicans, 

 there are double-flowered forms, C. 

 monstrosa, bearing golden rosettes, and 

 C. minor fl.-pl., a small kind. There 

 are also C. leptosepala, a Californian 

 kind, and C. purpurascens, distinct 

 and handsome, about 1 foot high, 

 with purplish stems, and bright-orange 

 flowers, the outside of the petals 

 flushed with a purplish tinge. 



The various forms of the Marsh 

 Marigold are handsome in colour, and 

 in groups or bold masses are effective ; 

 and they are easily grown, and increase 

 freely. 



CAMPANULA (HairbelT).K large 

 family of northern pasture, mountain 

 and alpine plants, many of these last 

 among the best for the rock-garden, 

 dwarf, graceful in form, lovely in 

 colour, and for the most part easy 

 to grow and increase. The tall per-
