The Tennis-ball Lettuce is remarkable for its extreme hardiness. Winter-grown plants, or those raised in cool, moist weather, will measure about ten inches in diameter, and weigh eight ounces; whilst those raised under opposite conditions rarely exceed seven or eight inches in diameter, or weigh more than four or five ounces.
It is slow in running to seed, and the head blanches white and tender. "It requires little room in frames in winter, and yields a great return in spring, as almost the whole plant is eatable." A large Cabbage Lettuce, tinted with brown about the head, is erroneously known in some localities as the "Tennis-ball."
Turkey Cabbage.
Similar to the Imperial Head; the principal if not the only difference consisting in the color of the seeds, which are black.

Head pale yellowish-green, large, long, and compactly formed; the exterior leaves are large, numerous, wrinkled, and coarsely blistered. When in its greatest perfection, the extreme diameter of the whole plant is about fourteen inches, and its weight twelve or fourteen ounces. The seeds are white.
This variety forms its head quickly and uniformly; cabbages white and crisp; is slow in shooting up to seed; flourishes in almost every description of soil, and at all seasons, except, perhaps, in extreme cold; and, though sometimes slightly bitter to the taste, is crisp, tender, and of good quality.
With the exception of its paler color, it resembles the Neapolitan. It is one of the best of all varieties for summer cultivation.
