INTRODUCTORY 
/ 
Y 
TlTH the view of giving the amateur a decided advance in quality 
^ ^ and value, all sales will be made from the following lists. 
Comparison with the varieties, sections and strains, will convince experi¬ 
enced growers that the increase in value and quality is far in advance of the 
prices charged, and the discarding of older varieties and strains that have 
not stood the test of competition is in the interest of the grower, and save 
him the cost of selection. The World’s Best Seedlings (Silver Trophy Strain) 
are the coming strain of commerce, and never fail to give satisfaction. 
The New Hybrid Seedlings are being yearly increased in value by the 
elimination of the more common shades, and by the addition of new and 
tested varieties of special beauty and vigor. 
The Silver Trophy Strain in its three sections also is receiving attention 
during the entire blooming season, to the end of purifying the colors in their 
respective sections. I cannot recommend these too highly. They should be 
largely planted. 
Groff’s Special Selections for 1904 are listed for 1906 as Gold Medal Col¬ 
lection, sections one, two and three; this stock being used in the preparation 
of the Gold Medal Collection. 
The leading novelty of this list is the World’s Fair Collection of Groffs new 
and rare Gladioli. 
No such collection was ever offered before in the world, and cannot be 
obtained elsewhere. In its preparation expensive named varieties are used, 
without regard to their cost or value, and hundreds of new varieties practically 
unknown; such diversity, quality, and value, was never before offered in any 
list in commerce.
