The link above should help.
I was given seeds for PSR-37 and made a separate offer here at Tville.In the link abve there were several who commented on what they got,the original origin of the seeds and I hope some of the many pictures are still visible.
And be sure to look at links within links as well as is also noted.
There was a similar discussion at the then idig and Bill Jeffers,akaTravis here at Tville also commented.
I haven't grown it myself for many years, no reason to but no doubt still have lots of older seeds left somewhere,but don't ask me where.
