Dutch Iris— DeGraaff. Hybrids 
‘This very distinctive group is of recent origin and has in a few years won interna- 
tional recognition. The flowers are not only superior in substance, brilliancy and purity 
of color, but also earlier, larger and of greater refinement than the old Dutch and 
Spanish Iris. The new Hybrids we offer are readily distinguished by the narrow orange 
stripe on the falls, while the older varieties have a larger yellow blotch. 
These iris are unsurpassed as cut flowers, since they will stand any amount of 
handling and traveling, while their earliness and good forcing habits make them valuable 
for the commercial grower and florist. 
‘Their hardiness and large color range have made them very popular for garden 
purposes, and, though in extreme climates they need some protection, they seem to do 
quite well as far north as New York. The varieties we list have been carefully selected 
to give the full range of colors and we have large stocks of the varieties that have proven 
most profitable in the English and European flower markets. We also have a complete 
collection of the latest novelties, which show great improvements. 
We sent a trial collection of our bulbous irises to Mr. Chas. Gersdorff, well-known 
iris breeder of Washington, D. C. He writes us: “I consider the reticulata, Dutch 
improved hybrids, new Spanish hybrids and Tingitana hybrid irises as ideal for garden 
use and for cutting for any amateur flower grower, for their ease of culture, hardiness 
and wonderfully beautiful long-keeping flowers. In my garden they bloomed from late 
February to late May.”
