DIRK DALEXS 



FROM WASHINGTON, D. C— 



After having grown a trial collection of bulbous irises, Mr. 

 Chas. Gersdorff, well known iris hybridizer and horticultural 

 specialist of Washington, D. C, wrote as follows: "I consider 

 the Dutch improved hybrids, new Spanish iris, 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 long-keeping flowers." 



FEOM NEW HAVEN, CONN.— 



Likewise, Mr. J. B. Wallace, Jr., past secretary of the Iris 

 Society, ordered a complete collection for trial in the test 

 gardens at Yale University in New Haven, Conn. He wrote 

 us that he was very much surprised at the manner in which 

 they so successfully grew and flowered, and that it was a 

 great pity that so few gardeners realized how easy they were 

 to grow.

DUTCH IRIS 



Their hardiness and the large color range has made 

 them very popular as garden sub.jects, the brilliant 

 elear yellows, flashing" blues, and sparkling whites 

 adding immeasurably to the spring border. 



As with the English group, they are perfect mate- 

 rial for cut flowers, as they will stand considerable 

 handling and may be shipped safely for long dis- 

 tances if cut Avhen in bud. 



These irises MUST BE PLANTED IN THE 

 FALL, not later than October. They are perfectly 

 hardy except in extreme cold sections, where they 

 should have a mulch of salt hay or tree boughs. 



If you are not growing them you are missing one 

 of the real joys of gardening. Use them in masses as 

 you would tulips or daffodils. Plant 4 inches deep.
