Seeking seed provenance

Submitted by Longma on Sun, 04/27/2014 - 02:18

I am trying to find the location data for some seed that was bought from Mr Ron Ratko approx. 10 years ago. The plants are now flowering and it would be very nice to establish their provenance, but I have no access to old catalogs or data sheets. Is there anyone here who has such access or can possibly put me in touch with someone who has please?

I used a nail file or simply my fingernail, to scratch away as much of the seed coat as possible, on every seed. The seeds were placed in leakproof ziplock bags, partially filled with water, and sealed.

Sorry this thread is a bit out of date, and I can't find one for 2013 and it's a bit late to start one now.

 

I have seed from one of the Exchanges of wild collected Clintonia uniflora and would welcome advice on when to sow and cultivation generally please.

(Moderator note: I've started a new thread, David, I hope successfully!  How about let's include "late 2013" in with the 2014 thread?    Lori)
