White clover, Trifolium repens (Fig. 161). Perennial, creeping 

 branches often taking root at nodes. Blooms from May on, 

 but especially in June-July, when it is especially valuable. 

 Honey light in color, granulates slowly, flavor superb. In 

 pasture lands and waste places in moist regions of United 

 States and Canada. Valuable as honey source chiefly in North 

 and East. Not cultivated, thrives in limestone regions. 

 Native of Europe and introduced into United States. One of 

 the most important sources. May be considered as a " stand- 

 ard " for comb-honey, being equaled by no other source for 

 this type of honey. Nectar- 

 secretion quickly affected by ad- 

 verse weather conditions. Honey 

 often mixed with basswood in 

 Michigan, Wisconsin and adjoin- 

 ing States. Also called Dutch 

 clover, under which name seed is 

 often sold. Other species of Tri- 

 folium are also valuable, e.g. sour 

 clover, T. fucatum, California. 

 Red clover, T. pratense, usually 

 has a corolla tube too long for the 

 honeybee to reach the nectar. At 

 times bees get considerable nectar 

 from this source. See also Crim- 

 son Clover and Alsike Clover.
