Was it The Seed Site? I can’t get a working link but if you Google it will come up.

Thanks so much, Floral. I am happy with any leads because it was so long ago that I have no memories of any details.

So interesting that the site is not linked in your post, but it was a live link in the email notification that Houzz sent.

Yep, I think the Seed Site too (tremendous resource for me).

This is also a fantastically useful site for seed collectors, growers or just for interest.

Yes, the seed site is awesome and not well-publicized. I hope it continues to be maintained because I use it every year! Rosaprimula, the hardy-plant site is fantastic, as well. Thank you so much for introducing it to us!
