needed to determine to what extent the day hlies described as 

 species are really good species or are merely clonal strains. 



Day lilies have a place in the flower garden. There is scarcely 

 a group of flowering ornamentals that can be grown so easily in 

 the temperate regions and is so free from insect pests and fungous 

 diseases. Although a single flower usually lasts but one day there 

 is a succession of flowers day after day and large w'ell-developed 

 plants, such as shown in Figure i, will produce a large number 

 of flowers during many days of bloom. The attractive grass-like 

 foliage comes early in the season and remains fresh and green 

 until autumn. The day lilies are especially effective in mixed 

 border plantings to which they will contribute a mass of rich 

 coloring in their due season. 



Possibly the progress thus far made in the improvement of the 

 day lilies is, after all, a mere beginning. Now that crosses in- 

 volving HemcrocaUis fulva have been accomplished, perhaps 

 further hybridization will more readily follow. Many new colors 

 or color patterns are possible — such as pure white and blotched 

 or spotted types of flowers. At any rate the breeding of these day 

 lilies at The New York Botanical Garden will be continued and 

 extended and attention will be given to the production of new 

 double-flowered types. The most desirable of the new forms 

 will be propagated as clonal varieties, named, and in due time 

 distributed.
