What a joy to grow these! They are quite compact and very productive, especially considering the compact size. They don't bolt prematurely. Even the secondary heads can be quite large in the right conditions. I actually just kept harvesting all summer into the fall on the same plants.
They taste good. I don't have a lot of varieties to compare it to but Waltham 29 might taste slightly better. Still, I doubt I will be growing Waltham anymore after these beauties.
Gave a great show. The flower seeds have fantastic yield. I still have flowers on November!
