Pyrethrum 



( 252 ) 



Pyrethrum 



of May. Frequent pinching is needed to keep the 

 plants from flowering and induce them to maintain 

 the dwarf habit that is desired. When Golden 

 Feather is employed for carpet bedding, as it 

 commonly is, this pinching has to be very drastic. 

 As the seed is very minute, it should only be 

 sown thinly. Frequently Golden Feather becomes 

 quite a weed in gardens, thousands of plants 

 making their appearance from self-sown seed, 

 which seems to be able to resist a considerable 

 degree of cold.
