Lettuce (Lactuca sativa)

Black Seeded Simpson: Early green leaf lettuce! Grand Rapids-type with light green color and tender leaves. Quickly produces a full-sized, bright green open head with slightly crinkled leaves. Withstands heat, drought, and light frost. A highly adaptable lettuce for plantings throughout the season. Popular babyleaf variety for a bright green contrast to mixes.
Days to maturity: 28 days baby, 45 full size


Oaky Red Splash: Arrowhead leaves are very long and soft with a bronze cast and speckled with red blotches similar to Freckles. Can be used as a baby leaf or open-head. Heads can grow to a very large size, up to 18” across in fertile ground. Midribs are often pink. Has a remarkably sweet flavor and silky texture similar to a butterhead. Thanks to grower and breeder Frank Morton for this beauty.
Days to maturity: 30 days baby, 60 full size


Salad Bowl: Bright green color with soft oakleaf edges and tender texture. Most commonly used for babyleaf production, favored for its shape, color and rapid growth rate. Full size habit is loose and open. Very attractive and always tender and sweet. AAS winner in 1952, and has remained a favorite for many years. Heat tolerant and bolt resistant.
Days to maturity: 28 days baby, 50 full size


Red Salad Bowl: A popular red complement to green Salad Bowl, with bronze-tinted oak-shaped leaves commonly found in standard salad mixes. Loose, open-heads form a medium sized rosette. Matures early and is very slow to bolt. Grows well in all seasons but color is best in cooler weather. Has shown field resistance to fall mildews.
Days to maturity: 28 days baby, 55 full size


Jericho Romaine: Summer romaine, with excellent heat and drought resistance. Produces a romaine head with a creamy texture and sweet flavor all season long. Hands-down winner of our taste trials every year. Lime-green leaves form large, somewhat loose, uniform heads. Available as raw and pelleted seed.
Days to maturity: 28 days baby, 57 full size


Winter Density: This unique variety combines the best lettuce traits into one. Part butterhead, part romaine, part green leaf—we love it, but we’re not sure where to put it in the catalog! Medium green leaves are tightly wrapped like a little romaine, around the lemon-lime heart of a butterhead. Prefers cool temperatures for germination.
Days to maturity: 28 days baby, 55 full size


I purchased Black Seeded Simpson, Oaky Red Splash, Salad Bowl and Red Salad Bowl seed from High Mowing for 2005. The Jericho Romaine seed was purchased for 2006 and the Winter Density for this year (2009).

March 13 (7 weeks prior to last freeze): Planted in peat pots in a popular potting soil. Four plants can go into a square foot. I'm planting five each since the Jiffy strips are five long.

March 27 (5 weeks prior to last freeze): The lettuce took longer to sprout than I expected, but it finally came up this week. It might be due to the fact that the seed is four years old.

April 7: Transplanted the lettuce to the garden. None of the red salad bowl sprouted. I got five each of the oaky red splash and jericho romaine and three or four of the others. I also didn't plant a second crop. I'll do that later, and probably directly outside.
