- Richard P.Verified BuyerRated 1 out of 5 stars9/22/25Very disappointed.
I tried planting the seeds 3 different times—even once after soaking—and not a single seed germinated. And I have flourishing herbs growing in the same pot. I watered regularly too. Can’t explain the performance. Maybe oldbseeds.
