I had replanted seeds ( 4/28) of several varieties that did not germinate. After I finished potting up seedlings the germination tray was taken off the heat mat and just left on a shelf where it dried out ( early June). About 2 weeks ago I re-wet the tray and about 7/20 3 varieties germinated-Pink Hing, Bahama's Finger, and Gambia Big Orange. ( along with some tomato seeds that had been in the same tray). I had seen this behavior with some of the wild varieties earlier in the year.
