    Yessir! They should get an adequate winter outdoors in your area to flower. I recommend deep pots (6 inches minimum).

    Progress report:

    Total of 8 germinations. I sowed 10-15 seeds, probably around 10 since I had so few to begin with. Red arrows indicate germinations. Blue arrow shows ungerminated seed.

    Nice germiation rate.Do you worry about moss growing or do you microwave it or similar to make sure it can't? And was that all the seed or did you keep backup cheers

    I still have some backup seed in case they might do better with some sort of treatment like stratification. I also gave some to Ivan Snyder but he hasn't tried to germinate it yet.

    They are in chopped long fibre sphagnum. I heated it wet and covered in a microwave oven on high for 3 minutes which is what Ivan Snyder normally does in for germinating seeds. The media should be changed or the plants should be repotted within a year if you do this.

    Nobody knew anything about germinating this species. It wasn't known if the same protocols for germinating Cephalotus would apply or not. Since the plants flower in the late spring to early summer and the typical environment is black wet peaty soils Robert Gibson thought a heat pad might help to simulate the conditions under the hot summer sun.

    I just sowed them on chopped sphagnum into a covered cup and put it under lights on my grow shelf. After two months of no activity other than the swelling of the seeds (usually a good sign), I partially uncovered the cup. Some seeds won't germinate in high humidity. Either the lowering of the humidity, seasonal drop of ambient temperatures or just passage of time seemed to trigger germination.

    'Seems like a very good germination rate and 2 months is nothing excessive when dealing with Drosera seed. A good, logical assumption working from Cephalotus seed methods.

    Very very impressive NaN! I have been trying to get mine to flower but no success yet. Congratulations on getting viable seed and germination. This sundew is underrated and one of my faves
