my daughter ( in the uk) sent me two pkgs of seeds when they first came out over there, about ten years ago.
there was a wide stripe on the packet... EXPERTS ONLY. the detailed and complicated instructions produced "zero" germinations for 1000 seeds. six months later she sent two more pkgs. the wide band read...EXPERTS ONLY - new, improved germination instructions. this time, one pack was done by the new instructions. zip, zero, nothing what so ever. the second package of five hundred went into a pot. some covered some not. then i tossed it outside for the winter. got three to germinate but lost them when i moved. good to see someone came through. cheers
