Dependable

If I could only plant one leaf lettuce, this would be it. I plant it year after year, I try others but always come back to Black Seeded Simpson. It has great germination, flavor, and I can coax it through mid-July without turning bitter. Then I plant for a late summer or fall harvest.

My experience

It was all good. All the seeds germinated, and they are growing nicely.

black seeded simpson lettuce

My shopping experience with Pinetree has always been 1st rate. I have been ordering from your company for at least 20 years and have always been satisfied. I really like the fact that you keep the prices very reasonable. Black seeded simpson lettuce is a variety I had growing up and is one of my favorites for flavor and speed of growth.

Grows well in the deep South!

I live in Houston and planted this variety in my 2018/19 fall/winter garden. It did very well. Tolerated 30F temperature and a light frost. Did not bolt until Spring temps hit 85+ regularly as in a week straight. Planting again this year!! Even when the heads are very large, leaves stay tender and succulent.

Have grown Black Seeded Simpson for many years as my dad did before me - it never disappoints. A must for every garden.
