CULTURE OF SWEET PEAS UNDER GLASS ^ 



The production of sweet peas under 

 glass is being extended every year due to 

 increase in prominence as a cut flower, and 

 hence their economic value in winter. 

 Greenhouse sweet peas as a cut flower rank 

 third on the market, coming after the roses 

 and carnations. They are thus grown in 

 nearly every state in the Union, usually, 

 however, in the vicinity of large cities. 

 Philadelphia, New York, Buffalo, Boston, 

 Chicago, Detroit, Milwaukee, Omaha, St. 

 Louis, Kansas City, Denver, and a num- 

 ber of other large cities offer good mar- 

 ket opportunities for winter flowering
