Most of the Petiolaris species are self sterile if they are of the same clone. I would make the attempt if the plants were grown from seed: you might get lucky.
<span style='font-size:12pt;line-height:100%'>Don't forget though that in living things there are rarely any absolutes.
I am attempting to self-pollinate as well as cross-pollinate my own Drosera dilatatopetiolaris plants which I managed to grow 3 individuals to blooming size from seed. However, they shared only two occassions when they each had a flower open at the same time affording an easy attempt to cross-pollinate.
Perhaps none of the flowers I self-pollinated will set viable seed or maybe the few that were cross-pollinated. Perhaps some will set seed, perhaps not. "Nothing ventured, nothing gained." I can almost be sure that if I had not made the attempt to pollinate them at all that there would be nearly zero chance of them producing any seed whatsoever. Now that I have self-pollinated most of these flowers, perhaps I will have eventually produced a few viable seed. Time and careful harvesting will tell.
Bottom line: Don't give up without a fight.
If I had listened to what was written in books about VFTs not being able to set viable seed from self-pollination I might not have been able to produce my own as early as I did (only had one plant at the time) and wouldn't have had the wonderful experience of germinating my own VFT seed and growing them to blooming size.</span>
If you do get seeds I hear that you can greatly increase germination by putting them in a paper bag,and place them in front of your heater in your house for a whole winter.
<span style='font-size:12pt;line-height:100%'>I have some seed received in trade from Tamlin, tentatively identified as Drosera dilatatopetiolaris. It was mixed with fine sand to facilitate sowing. Tamlin said its identification was uncertain. I planted some a few weeks ago, here they are now, looks like they might be the real thing:
I am suspicious. Have reserved hope, but although the seedlings are too small to really tell, something strikes me as wrong. I thought seed I sowed of this batch came up as D. dielsiana and suggest you compare the seed testa to see how it compares with other D. dielsiana.
<span style='font-size:12pt;line-height:100%'>Below is a photo of one batch of Drosera dielsiana seed at 200X magnification. I will post photos of other D. dielsiana seed when I get the chance.
All the Drosera dielsiana seed I have photographed, so far, have a more or less pronounced spindle shape with the narrow end having a little sharp point.
