258 HARDY SHRUBS. 



double white forms. They are increased by working on one-year-old 

 seedling stocks of the common peach. 



PHILADELPHIA (flock Orange, Syringa) All of the species and their 

 forms are valuable flowering shrubs with large white flowers, some 

 of which are very fragrant. P. coronarius is one of the best known; 

 P. c. primula^florus has double flowers; there is another with yel- 

 lowish leaves. P. grandiflorus is a native of the Southern States; it 

 has larger flowers than P. coronarius. P. Gordonianus is a late 

 bloomer, with almost scentless flowers. They succeed in almost any 

 soil. Cuttings taken after the leaves drop in Autumn will root very 

 quickly if put in slight bottom heat in March or April; or in a protected 

 place they root well in the open ground. Pruning should be done only 

 after the flowers have faded. This will give the young wood an oppor- 

 tunity to ripen. The flowers are only produced on the wood made the 

 preceding Summer. 



POTENTILLA FRUTICOSA (Shrubby Cinquefoil) A very hardy species 

 growing from 2 to 5 feet high, with pinnate leaves and numerous bright 

 yellow flowers, which are produced all through the Summer. Cuttings 

 may be rooted at any time indoors during Summer. Small plants are 

 very suitable for the rockery, and by pruning in the Spring they are 

 easily kept within bounds . 



PRUNUS PADUS is the Bird Cherry. It bears long racemes of white 

 flowers, in May, followed by ornamental black fruit. P. spinosa flore- 

 pleno, the double flowering Sloe, forms a large shrub, usually covered 

 with double white flowers in early Spring. The dwarf white, double- 

 flowering Almond is P. japonica flore-alba-plena; the red form is P. j. 

 flore-rubra-plena. They bloom for only a short period, but are exceed- 

 ingly handsome while the flowers last. P. Pissardi is the purple-leaved 

 Plum, of which there are g-ood and bad forms; the good varieties retain 

 their coloring till the end of the season. The flowers, usually borne in 

 great profusion, open in early Spring before the leaves expand. In this 

 locality the fruits are ripe by the end of May. Most of the species and 

 forms are propagated by budding and grafting, but it is cheaper to buy 

 than to work them in small quantities. 



PUNICA (jRANATUn NAN A (Dwarf Pomegranate) Both the tall 

 growing and dwarf Pomegranates stand our most severe Winters here 

 without the least injury, and flower quite profusely during the Summer. 

 They are all the more welcome, as their unique, bright scarlet flowers 

 are produced when shrubs in bloom are scarce. In favorable seasons 

 they ripen fruit, but we do not depend upon these for propagation. Cut- 

 tings are taken from one and two-year-old wood, stored and put in a 

 cool house propagating bed about the middle of February ; they root 

 very evenly. They should be removed to a frame as poon as they will 

 bear it. The dwarf form makes a very ornamental shrub, and should 

 be tried wherever it is likely to thrive. Native of Cabul and Persia. 



PYRUS (Crab-apple) Highly ornamental low growing trees, usually 

 covered with flowers early in Spring. Some of them have very highly 

 colored fruits in Autumn. They are increased by budding and grafting
