Species that will Germinate without Pretreatment

Filed under Customer FAQ's, Species and Product Overview
Quite often, customers ask us for a list of species that do not require any stratification; those that could be planted in Spring and will germinate when the soil temperatures warm up. We classify these species under germination code ‘A’ meaning:
Germ Code A: Seed should germinate upon sowing in a warm location. No pretreatment is necessary other than cold, dry storage (also called dry cold stratification). Seed purchased from Prairie Moon has been stored under these cold, dry conditions.

Wow, what a helpful posting! Thank you for providing this information.
Odd – I looked at Veronicastrum virginicum as one of the seeds listed above needing no pretreatment. On the species page, however, the germination instructions say that Prairie Moon Codes C and D (including 2 months of cold-moist stratification) are required.
I also believe that seeds listed above have been stored under cold, dry conditions.
What is the proper treatment?
Thanks.
Hi Amanda! I see that in the body of the species page – sorry, that is wrong! I just deleted it. Code A and D are correct. Thanks for pointing that out.
