Re: Sprouting Rosa rugosa seeds

>From my website:     Rosa multiflora    WC 7 d, 40-70-40-70

The cryptic coding above means:
Vigorously wash the seeds three times per day for 7 days, then
sow @ 40F for 3 months, followed by 3 months @ 70F, followed
by 3 months @ 40F, and upon their subsequent return to 70F
you will begin to get some germination in 10 to 12 weeks.

If you visit my website, you will see that all of the Rosas are
multicycle germinators, and many of them are far more difficult
than R. multiflora.

I don't have any info specific to R. rugosa.
