I have been shopping for seeds of all sorts on ebay. I don’t know how good they are yet. I just got the first bundles in the mail today. I plan to germinate one of each thing, or try, to see if I got a good deal or not. I found several items for very good prices, if they are reliable. You may find some choices there. I saw seeds for all climates listed. I think if you do choose to buy though, just try something first, to see if you have an honest supplier. I got some poppy seeds I hope will thrive. They are so bright and their limber stems gives the appearance they dance when there is a breeze.
When you do find a supplier you like, have fun growing!
