LIST OF PLANTS 163 
a pot plant grown in loam, leaf-mould, and sand. It 
will also thrive as an edging to greenhouse stages if 
planted in moist broken coke or gravel. Cuttings strike 
readily in spring in warmth. | 
PINEAPPLE (Ananas).—Both those sorts grown for 
fruit and those with variegated foliage are raised from 
suckers, and sometimes the crowns of the fruit are used. 
A few of the lower leaves should be removed, and after 
potting in fibrous loam they should be plunged in a 
brisk bottom heat and water given sparingly until roots 
are plentiful. 
Pinks.-—These old favourites may be propagated like 
Carnations, but pipings are generally used. These are 
young shoots pulled from the base of the old plants after 
flowering. A few of the lower leaves are removed, the 
bottem end is cut through close below a joint, and the 
pipings are inserted in prepared sandy soil in a shady 
border and covered with a hand-glass until rooted. 
PLEeROMA (Tibouchina).—Cuttings of these beautiful 
blue and purple flowering Melastomads root readily in 
bottom heat during summer if covered with a bell-glass. 
Pium.—Shield-budding in July and August is the 
method generally employed on stocks of Damson, 
Mussel, St. Julien, and White Pear Plum. Grafting, if 
desired, may be done in March. The stocks should be 
headed back early in the year, and the shoots intended 
for the scions cut at the same time and laid with their 
ends in the ground in a cool place to retard them. 
Wood buds (not blossom buds) must be used in all 
cases. 
PLumMBAGO.—The beautiful greenhouse climbers P. 
capensis and its white variety are propagated by cut- 
tings of young shoots, 3 or 4 inches long, taken off with
