PECULIARITIES OF THE PLANT 
Artichokes grow well in any soil or -climate but viable 
and desirable seed tubers can only iie produced itf-the 
north temperate zone. Further sgi^th the growth.from

In the north temperate ~*TTTit (hii (jilt freezing* “sets” 
the skin on the tuber and holds it soul 
against the spring awakening. 
It also appears that the seed stock which is frozen 
during the winter months is much more viable than 
when grown in warmer sections and replanted soon 
after maturity. 
Desirable seed can be raised only on the lighter or 
sandy loam soils, although any soil, the richer the bet¬ 
ter, will produce highly satisfactory tubers for table, 
commercial, live stock or processing uses. 
BRIEF CULTURAL RECOMMENDATIONS 
Technical Bulletin No. 514, U. S. Dept, of Ag. 
Grow only strains known to be high-yielding and of 
acceptable composition, color, and shape. 
Use only good, sound seed tubers that are free from 
injury and disease. 
Plant as early as the soil can be properly worked in 
the spring. 
Plant seed pieces approximately 2 ounces in weight, 
preferably whole, but cut if necessary. 
Except in unusually favorable regions for the crop, 
as in the semi-humid, western part of Oregon, plant in 
rows 3 feet apart with seed pieces 2 feet apart in the 
rows. In localities comparable to Corvalis, Oreg., plant
