Hi Dean. I have a batch of gentian acaulis under the lights now. I tried the Rocky Mountain Rare Plants method of freezing them for three weeks and now I've had them at 70 deg. for about three weeks so far. As of this morning nothing has germinated, but I should be getting something within the next week. Sow them on top of the soil. I'll let you know how I make out. Jim Mc Coy Zone 5 Northwest New Jersey
