DREER'S 



SINGLE=FLOWERINQ 



Pyrethrum Hybridum. 



Too much cannot be said in favor of this grand old-fashioned 

 Hardy Perennial, which is nicely shown on the plate opposite. 

 They are easy to grow in any good garden soil where there is 

 good drainage and full exposure to the sun. They prefer to be 

 left undisturbed for two or three years, and if given an annual 

 topdressing of well rotted manure flower generously. Their 

 main season of blooming is in June, but if the first crop of flower 

 stems is removed as soon as finished they will give a fair sprink- 

 ling of flowers during the summer and autumn months. The fine 

 fern-like foliage of the plants is attractive at all times. 



The plants which we offer have been grown from a selected strain of 

 seed, and embrace all the colors from deep red through the various shades 

 of rose to pure white. These can be supplied in strong flowering plants 

 in mixed colors only.

DICTAMNUS (Gas Plant). 



A very showy border perennial, forming a bush about 2h feet in height, having 

 fragrant foliage and spikes of curious flowers during June and July, giving off on 

 warm, sultry evenings a fragrant volatile oil, which ignites when a match is applied 

 to the stem directly under the head of flowers. They require a heavy, strong soil 

 and an open, sunny position. It is not advisable to transplant often, as they improve 

 with age, it being one of the most permanent features of the hardy herbaceous border. 

 Instances are known where this plant has outlived father, son and grandson in the 

 same spot. (See cut.)
