All 3 seeds popped and the weed is good. The downside is the yield. These plants grow fast.

Never came up out of the ground Where is the rest of my review . I wrote that I soaked the seeds in water for 24 hours. Then put them between 2 pieces of soaking wet with water. When the seeds sprouted I put them in the ground. The seeds never came up to grow. I have been purchasing seeds from Seedman for years and never had this happen. I would want a full refund also with the shipping cost. Thank you I placed the seeds in water 24 hours. I then put them ina water soaked paper napkin, covered them with aanother soaked napkin. When they sprouted I placed them in the soil of my garden. I have been using this method for 4 years. I have always had great luck with the seeds you sold me.Not this year. I would like to be reimbursed for the price of the seeds and shipping
