GENERAL DISCUSSION ON FLOWERS. 75 



Pin Oak. An oak should not be left out of the list and there is 

 nothing finer than the pin oak (Quercus palustris). 



Tulip Tree. This should be one of the twelve. 



Varnish Tree {Koelreuteria pcDiiculatd). This ti'ee although 

 structurally not imposing is valuable on account of its 

 summer flowering habit. 



Best Twelve Hardy Shrubs. 



Double Flowei'ed Plum (^Prunus triloba). Our showiest, early 



flowering plum. April and May. Grows to six or twelve 



feet. 

 Golden Bell (Forsythia Fortuni). AVith its wealth of yellow 



flowers. 

 Spiraea Van Houttei. A graceful, hardy shrub, bearing dense 



racemes of white flowers early in the season. 

 Early Mock Orange {Philadelphus coronarius). More graceful 



than the larger flowered P. speciosissimus. 

 Japanese Snowball ( Viburnum plicattcm). Perhaps a little 



tender for an unusually severe winter. 

 Dwarf Horse Chestnut (Paoia niacrostachya). 

 Honeysuckle. The honeysuckles are all fine, but considering the 



berry-bearing effect through to the fall, Lonicera Morroioii 



is perhaps to be chosen. 

 Russian Rose (Posa rugosa). Its showy fruit hardly less dec- 

 orative than its large single flower. 

 Hydrangea {Hydrangea paniculata). One must choose here 



the hardy species rather than those of greater grace or florif- 



erousness. 

 Thunberg's Barberry. Nothing better for a hedge. 

 Deutzia gracilis. 

 Lilac. The best is the Rouen lilac {Syringa Rothomagensis) . 



Best Twelve Perennial Plants. 



English Cowslip {Primula officinalis). The best old-fashioned 

 perennial for early bloom.
