Where I am in Canada, they seed out in August. If it wasn't for complications with international shipping, I'd have no issue sending some as I'm surrounded by acres of them.
Best of luck in your searches.

i got mine over the winter from a guy on eBay. got 500 seeds for $10 free shipping. i grew out 3 of them starting indoors in march . i just planted them out and they were already 3-4ft.

I had good success with germination they just don’t really love it this warm so far.
they are a cold weather shrub. surprised they even survive in VA. they love my z3b weather.
