THE CANADIAN HORTICULTURIST. 99 



Papilionacea. A very showy white flower, large and full, the 

 outside petals having the slightest tint of pink which is gradually lost. 



Delachii. The color of this is a very dark purplish crimson, quite 

 •double ; a very striking and handsome variety. 



Pottsi. This is not as double as Delachii, but the coloring is more 

 brilliant and lively, and the contrast presented by the numeit)us bright- 

 yellow anthers with the deep crimson petals is very pleasing. This 

 variety has the singular habit of yielding single flowers, or nearly so, 

 in some seasons, wliile in others they are quite double. 



Festwa Maxima. A very large, full, double, gobular, white flower, 

 having the centre petals streaked with a few marks of carmine, which 

 greatly relieve and enrich its appearance. One of the most beautiful 

 and showy of this beautiful race. 



Ilumei. Color, purplish rose; flower large very full and double, 

 one of the latest bloomers, continuing the season of Peonias for nearly 

 a month. 



Queen Caroline. The form of this flower is cupped, like a rose, 

 which it very much resembles also in color and fragrance. It is of 

 .great size and exceedingly showy. 



Whitlejii. A very large flower, \niite, with a slight lemon tinge 

 to the centre petals, very full and double and fragrant. 



With these varieties placed in clumps among the shrubbery, or, if 

 preferred, massed in a bed, there will be no lack of beautiful flowers 

 during the month of June. TBeir culture is of the most simple and 

 easy kind. Once planted they should not be disturbed for many years, 

 I'equiring only a top-dressing of well rotted manure in the spring to 

 stimulate their growth and increase the size and beauty of the blooms. 



THE APHIS, OR PLANT LOUSE. 



This pest of the greenhouse and window-garden does not often 

 attack our orchards in such numbers as to become a source of alarm. 

 It seems from Mr. Woolverton's article on page 101 that they have 

 appeared in some orchards about Grimsby in unprecedented numbers, 

 and it will be interesting to learn how seriously they injured the trees 

 or affected the crop, and with what measure of rapidity our friends the 

 Ladybirds succeeded in diminishing their numbers.
