I have purchased seeds for Mock orange

I am trying to find out what type of mock orange this is, the seeds are tiny red. Do you have any info how to start these seeds?

Doug says that you don't say which Philadelphus you have but in general you'll have the best luck with treating it as a perennial and not freezing the seed but giving it a cool germination time and sowing on the surface rather than burying the seed. See the propagation pages here for perennial info.

Good luck - let me know how you do.
