96 MY SHRUBS 
shy of blooming at all; but the young foliage is most beautiful 
and the shrub a worthy resident for a sunny wall. 
Purshia tridentata is a little American shrub with yellowish 
blossoms of no great charm, but the triple leaves are neat and 
distinctive. 
Pterocarya caucasica, of the walnut race, is a tree, and, unlike 
some tardy growers, will soon show you that it is. But encourage 
it in a corner for the sake of its youthful grace and beautiful ash- 
like foliage. When it outgrows your garden patch, the fate of 
other too pushing, too busy people may fall upon it. 
Pyrus, in the shape of the flowering crabs, you cannot deny 
yourself. P. floribunda and P. spectabilis should join you. I have 
P. arbutifoia from North America, a small species, whose shining 
autumn foliage turns to most splendid crimson before it falls. 
P. “ Fohn Downie,” too, is a most splendid object in spring and 
autumn. None fruits more handsomely than this. P. salicifolia 
argentea pendula must be a fine thing when successful, but my 
standard of this beautiful shrub sulked and never took kindly to 
its new home. I must try again. 
Of tiny sub-shrubs, Pyxidanthera barbulata, from New Jersey, 
succeeded with me on a sunny rockery for a season. The Pine- 
barren Beauty has a prostrate habit, and might easily be mistaken 
for a saxifrage. Some dire disaster overtook my plant, and it died 
suddenly from causes beyond my power to diagnose. I now have 
it again in peat in a pan, which is plunged in a shady corner for 
the greater part of the year, and blossoms under a cold frame during 
April. It is then covered with buds like pink pearls, that break 
presently into little white, fairy, five-petalled flowers. But Pyxi- 
danthera does not derive from pixy.
