From a single rhizome planted in 

 1942 this crowded clump was over- 

 due for dividing in 1947. Note rhi- 

 zomes growing over one another in 

 center of clump. 



After being dug, clump was 

 cleaned with stream from hose. Note 

 that healthy, growing rhizomes circle 

 the clump, while those in center have 

 very few white feeding roots. 



HOW TO DIVIDE 



Healthy, growing rhizomes are 

 separated from old bloomstalks. 

 Some prefer "doubles" as in fore- 

 ground for replanting. Wash rhi- 

 zomes thoroughly before replanting.

The above series of pictures is taken from the new book 

 "THE IRIS, AN IDEAL HARDY PERENNIAL," recently 

 published by the American Iris Society. It has been a long 

 time since a good Iris book has been available, especially 

 one of an up-to-date nature. This one is as nearly com- 

 plete as the experts have been able to make it — chapters 

 on the various groups, types and species, every phase of 

 culture, the fine points of Iris breeding, diseases and pests, 

 all about the American Iris Society, Iris judging, photo- 

 graphy, use of Irises in the garden, and so on. 224 pages, 

 well illustrated. Heavy, leather-like paper binding, $1.50; 

 permanent cloth binding, S2.50. Send your order to us 

 and we will ship promptly. 



JOIN THE AMERICAN IRIS SOCIETY, membership in 

 which will bring you four meaty bulletins per year. This 

 is the best way to keep informed on Iris progress, the 

 latest cHA^ards, what the experts think. These bulletins are 

 really books themselves, generally containing 100 pages 

 or over per copy. Dues $3.00 per year and well worth it. 

 Send your remittance to us, we will enter membership 

 for you. 



Come to Oregon in 19491 The annual meeting of the 

 American Iris Society will be held in Portland, Oregon, 

 in early mid-May next year and you will have a rare 

 opportunity to see many famous Iris gardens of the Pacific 

 Northwest at their best. Start planning now to be among 

 those present. 



A FEW CULTURAL TIPS: While it is true that Irises 

 are among the easiest of all plants to grow, anyone who 

 plans to grow even a few Irises should not be content to 

 achieve merely indifferent results. Most Irises will suc- 

 ceed well in any type of soil from almost pure sand to 

 stiff clay. Where one may choose, a medium heavy, 

 fairly well enriched soil — in other words, ordinary good 

 garden soil — is to be preferred. Go easy on fertilizers, 

 especially animal fertilizer; this sometimes promotes lush 

 growth and eventual rot! Bone meal, well worked in, is 

 safe, and good. 



Don't plant in deeply shaded situation, and avoid 

 places where roots of large trees or big shrubs rob the 

 soil of plant food and moisture. Be sure drainage is good. 



Plant at least two feet apart; after first year, sparse 

 appearance will have vanished. If immediate effect is 

 desired, plant in groups of three of a kind, about a foot 

 apart, the groups at 3-foot intervals. 



DISEASES AND PESTS: Although comparatively free 

 from garden enemies, soft rot of the rhizomes or spotting 

 of the foliage sometimes manifests itself. The former, 

 usually the result of poor drainage or an over-wet season, 

 can be controlled by cutting back to sound tissue or 

 replanting. Leaf spot, like the measles, is not fatal. Cut 

 away and burn infected foliage and dust with copper or 

 Bordeaux solution. For Iris borer, or more detaiied in- 

 formation on any of these subjects, drop a post card and 

 ask for our 3-page leaflet on "Culture of Bearded Iris." It 

 was included as an insert in last year's catalog, but it will 

 be sent without charge to anyone requesting it.
