WALLER FLOWERSEED COMPANY 
TRYSOMIC GIANT IMPERIAL STOCK 
Based on studies commenced by Dr. H. B. Frost at Cornell University in 
1915 and furthered through consultation with our late co-founder Dr. J. H. 
Franklin during the ’20s, the genetic theory of Trysomic doubles in Stocks was 
developed and was proven by 1930 to be capable of producing 85% doubleness 
from seed. 
In addition to this desirable trait, the percentage of any planting can be 
increased up to 100% at the four-leaf seedling stage as at this period of growth 
the young singles are noticeably weaker and can be readily distinguished from 
the vigorous double flowering plants. 
At this date of introduction, the Waller Flowerseed Company is the only 
grower with experience in this new field. 
In all other respects the Trysomic Giant Imperial Stock is identical to cur- 
rent normal double strains.
