A Gardeners Forum Forums General Discussion The Plants and Flowers Forum wild phlox help

So I was given two little baggies of perrenial wild phlox seeds and have kept them in a small temperture controled green house kit. I have placed about 15 seeds in this green house about three weeks ago and have seen no germination. Should I give them more time or is there something wrong? I recieved no instruction with these seeds.

Thanks,

Depending on the exact type of phlox, some require darkness to germinate, so the seeds need to be covered. Some perennial phlox need a cold period of about 4 weeks to germinate.
