PRACTICE OF GARDENING. 



Part III. 



6523. Propagation and culture. The same as for herbaceous plants, taking into consideration the dif- 

 ference in the soil and site. 



Subsect. 5. Flowers for ornamenting Rocks, or Aggregations of Stones, Flints, Scoria; 

 formed in imitation of Rocky Surfaces, §c. 



6524 In strict propriety, mountain or rock plants only should be introduced on artificial rock-work ; 

 but natural mountains and rocks are always moist and cool, and the plants which have their habitations 

 there would not always thrive on dry ridges of earth and stones. On a small scale, therefore, choice is 

 generally made of such plants as are not tall and rampant, and as grow naturally in a dry .soil. In the 

 following list, as in the others, the most ornamental of them are distinguished by a letter (s), and those 

 which flower the greater part of the summer by a figure (3), &c.

6525. The ground-plan and figure of the elevation of the rock-work must, as in the case of the aquarium, 

 be made to harmonise with surrounding objects. Simple outlines and surfaces, not too much broken, 

 show the plants to most advantage, and are not so liable to ridicule as imitations of hills or mountains, or 

 high narrow cones, or peaks of scoria? in the Chinese manner, which are to be seen in some places, 

 A eround-plan, in the form of a crescent, or of any wavy figure widest towards the middle par* of its 

 length and with the surface not steeper than forty-five degrees (Jig. 619.) will be found well suitea to the 



less durable materials, such as bricks, pudding-stone, scoriae, &c. which are found in flat countries. 

 Sometimes one side of such rock-works may be nearly perpendicular, in which case, if facing the north, 

 it affords an excellent situation for ferns and mosses. 



6526. In countries abounding with stone, massy and extensive pieces of rock- work may be rormed, and 

 shrubs introduced as well as plants, so as to produce a scene of considerable beauty and interest. Its 

 base, and such parts as are near the eye, may be formed of masses of granite or bassalt ; selecting such 

 for the shady side as are already covered with mosses and lichens, especially the lichen atra-flavus, geo- 

 eraphicus, ventosus, stellaris, &c. These vegetables will not grow on sandstone, and but seldom on 

 limestone, therefore stones of these earths should be kept as much as possible in the more distant parts, 

 where they will be partially covered with shrubs and plants, rooted in proper soil, introduced in the 

 crevices. When works of this kind are extensive, a winding walk or stair may be led over them, and 

 wells, or small reservoirs of water, introduced in some places for mountain bog-plants and aquatics, and 

 for keeping the whole mass moist and cooL 



Subsect. 6. Evergreen-leaved Flowers, or such as are adapted for preserving an Appear- 

 ance of Vegetation on Reds and Rorders during the Winter Months. 



6527. A due proportion of evergreen-leaved flowers is very necessary for enlivening borders in the winter 

 time, and more especially in dug compartments on a surface of turf, which, without some evergreen plants, 



ook dreary by contrast with the verdant surface.
