| Black Seeded Simpson
45 days — 'Black Seed Simpson' is a non-heading, large, upright, compact leaf-type lettuce with light green, wide, curled leaves. It is a very early, dependable, and productive variety. It is also very heat tolerant and slow to bolt.
When it was introduced in the late 19th Century, seed companies all quickly added it to their catalogs touting their attributes and benefits. Since it was larger in size, of improved quality and more productive than the older 'Curled Simpson' variety, it has been one of the most popular leaf lettuce varieties for over 130 years.
So far, the earliest release date that we have found is from the 1879 Peter Henderson & Company catalog although other accounts date it back to 1850. Each packet contains one gram, which is approximately 500 to 600 seeds.
