Hi John,
I do not have seedlings for trade, but there is a nursery where you can order Azalea and Rhododendron liners and rooted cutting at very low prices. If you do not mind waiting for several years for the shrubs to grow, you can try them.

Here is a link that might be useful: Azalea cuttings

I have some Rhododendron cuttings that I can trade. If interested, email me and I will tell you all I know about them. I belong to the Rhododendron Society of America and I got these cutting from a member who does a lot of hybridizing of his own. I have several from him that named but not commonly on the market.

Let me know
