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."
Vilmorin 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 remarkable 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, 1878, p. 2).

Italian Giant.—There are two or more forms of this variety in the market. For example: Vick sells "Italian Giant;" Gregory, "Italian Early Giant;" the Plant Seed Company, "Italian Early Giant Autumnal;" Vilmorin, "Half-Early Italian Giant (new);" Frotzer, "Late Italian Giant;" and Vilmorin, "Late Giant Italian Self-protecting." The early form or variety seems to be the most generally sold by our seedsmen, and is perhaps the one indicated when the simple name Italian Giant is used. Gregory calls the Early Italian Giant a "fine, large white-headed early Variety." Frotzer says it is not quite so late as the Late Italian, almost as large, and in every way satisfactory. The Late Italian Giant, he says, is grown to a considerable extent in the neighborhood of New Orleans, and is the largest of all the cauliflowers and should not be sown later than June, as it requires from seven to nine months to head.
