Contrary to popular belief, FDA guidelines specify that any product - flour, pasta, bread, pastry etc - labeled as "Whole Wheat" must contain only whole wheat flour, in other words, 100% whole wheat. No other type of flour can be used or listed as an ingredient. The 51% rule commonly quoted (that Whole Wheat bread only has to be 51% whole wheat) applies to the FDA's more ambiguous term "Whole Grain" health claim, which is a whole other can of worms. From the FDA regulations website:
(a)Whole wheat flour, graham flour, entire wheat flour is the food prepared by so grinding cleaned wheat, other than durum wheat and red durum wheat, that when tested by the method prescribed in paragraph (c)(2) of this section, not less than 90 percent passes through a 2.36 mm (No. 8) sieve and not less than 50 percent passes through a 850 [micro]m (No. 20) sieve. The proportions of the natural constituents of such wheat, other than moisture, remain unaltered.
*What's important: the last sentence calling out the "natural constituents of such wheat", which means that all parts that make up the wheat kernel must be present in the flour. ALL components, meaning bran, germ and endosperm. If sifting or blending were permitted, this regulation could never be met.
**The first part of the regulation is the FDA setting a particle size standard, that whole wheat flour must be milled finely enough that certain percentages of particles pass through particular sieves. It does not mean that whatever doesn't fit through the sieves can be discarded.

Refers to the Winter planting season. Winter habit varieties require a long total time in the ground and grow best after fall planting and initial establishment with prostrate growth, followed by a prolonged dormant time under snow; they grow upright in the warmth of spring and come to fruition during summer, but they cannot tolerate really severe winters such as in Canada. Winter habit types show prostrate initial growth. It appears that in California, winter habit types can be planted until Valentine’s Day, so that they are above ground and well established before the Spring Equinox; planted later they do not come to fruition satisfactorily.
