Welcome Chosendia! I see you just joined DG today! Wondering what part of the country or world you are from? What other plants do you grow?
If you are looking for some rarer Japanese Morning Glory seeds, I get mine from Onalees. She sells them in the original unopened Japanese seed packets. They are a little pricey, but they usually come true and are lovely. She sells mixed cultivars too. :-)
We do an annual seed swap once a year here in late Fall, which is another way to get seeds. :-)
If you don't want to waste gas, just go to ebay and type in morning glory seeds. They are quite the mg gallery. This place is hot in the winter months after every one has harvested seeds. Hope it helps. Frank
