They are not hardy, at least not in any of the northern 

 states. The tubers should be carefully lifted after the 

 foliage has all "ripened off" (which occurs usually 

 toward the end of Augiist), and stored until the foUow-

ing spring in some cool shed where they will not freeze. 

 They should be planted as soon as the frost is well out 

 of the ground in spring, about 2 inches in depth and 

 about 6 inches apart, making the soil very sandy on top 

 so that the leaves will push through readily without 

 heaving the soil. Like their congeners the European 

 Ranunculi, they like plenty of moisture at the roots dur- 

 ing the growing season, and if they can be shaded from 

 the sun when in flower their blossoming period will 

 be materially lengthened. They may also be grown for 

 flowering in the greenhouse. The writer usually grows 

 a few pans each year, planting the roots in pans of light 

 soil towards the end of January and placing them in the 

 coolest greenhouse, where thcv will blossom towards 

 the middle of April. The writer also prefers the Tur- 

 ban varieties, since they are stronger-growing and rather 

 larger than the Persian. The species may be propa- 

 gated by seeds, but this process is not worth while for 

 most people because the bulbs may be procured so 

 cheaply. 



Of the native and European species of Ranunculus, 

 those of the Batrachium section, such as J?, aquatilis 

 and its varieties, are interesting aquatic plants, while 

 B. repens, var. flore plena, and Jf. amplexicaiilis are 

 useful as subjects for the bog garden.
