I recommend this product

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.

Always a must in our garden

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

Pinetree has always been good to me

I've been ordering from Pinetree for several years and purposefully made comparisons by buying the same seed from other vendors. I keep coming back because I always get better results here. Keep up the great work. Thanks.

And oldie but a goodie

Mild, tender, goes through several cuttings in my "cut and come again" container garden. Dependable and very slow to bolt.
