WOODRUFF’S A-36 ws. ; - »  seSOtdave 
Plant: Medium to large diameter, large frame, short stem. Wrapper 
leaves protect the head from the sun. Foliage very dark green. Leaf 
size is large, with finely divided wavy edge and an exceedingly refined 
blister, lacking the coarseness of Great Lakes, Imperial 44 and 456. 
Heads: 612” wide x 6” deep. Outer head leaves are firmly attached in 
a way that reduces wrapper loss when cutting and trimming. Head 
is very solid, interior well blanched, medium size core. Good long 
distance shipper. 
Tolerant of hot sun and showed no tipburn at Milford. Holds up well under 
wet weather conditions and is at least tolerant of bottom rot or leaf drop. 
Heads remain marketable long and do not burst nor develop brown midrib 
necrosis as does Great Lakes under adverse conditions. A field can be cut 
clean in two cuttings. The variety has a vigor that is lacking in many of the 
modern, closely inbred strains.
