The stock of this variety is all controlled by 

 Peter Henderson & Co., and is grown in Germany. 

 Seed descended from Henderson's stock has been 

 grown at Puget Sound, and is claimed to be as good 

 as the original. Several other sorts, including 

 Puritan and Padilla, have been derived from Hen- 

 derson's Snowball, which often mature quite as 

 early as this variety.

IMPERIAL. May says, in the Revue Horticole, for 

 1880: " A variety which seems to have originated 

 from the Early Dwarf Erfurt, being a little more 

 vigorous, and producing a little larger heads, which 

 is without doubt a result of culture, for in head 

 and leaf it wholly resembles the Erfurt. It is an 

 excellent variety, employed in the same manner as 

 the Erfurt, and deserves extended cultivation." 



Yilmorin says: "This fine variety resembles the 

 Dwarf Early Erfurt, but it is of deeper green, and 

 every way larger. It is an early variety with 

 beautiful white head, large and solid, and remark- 

 able for its regularity of growth and product. 

 When well grown it is certainly among the most 

 desirable early varieties." Thorburn considers it 

 one of the best for the main crop. It originated 

 about 1870. It matured in one season eighteen 

 days and in another thirty -two days before the 

 Lenormand. (The Garden, 1873, p. 2).
