Thank you!
Yes, that is interesting! I suppose it's a photoperiod change thing. Mine indoors are blooming too.
Thanks Ivan! Yeah, there are a lot of places like that around here. I will! These places seem stable so far. I've made leaf cuttings of this population and currently have seeds of the progeny of those plants I collected today. Want any seeds?
Thanks, you're welcome!Beautiful
Thanks for sharing.
Thanks. Really no challenge. A treat to grow. American pygmy; interesting. @hcarlton , might a brevifolia x pygmaea be possible?
An interesting update. It seems smoke paper treatment induced germination in my plants. I, Ivan, and another have been having difficulty germinating seeds from my plants. I collected two separate locales in Gainesville/Alachua County FL, and grew via leaf cuttings. They both flowered in my care and I collected seeds. I sent seeds to an acquaintance three times and they never got germination without treatment. Ivan got that one plant miraculously. I tried myself and got none. Ivan told me he got seeds from his plant above but none of the seeds germinated.
He suggested perhaps they may need smoke treatment. So I purchased smoke paper discs and did an experiment outlined below:
11/15/25
Instructions from company: 1 paper disc for 50mL.
I used 1/4 in 10mL dH2O
D. brevifolia 'CR1475' - had 25 seeds, so 12 seeds used for water and 13 for smoke disc (harvested 4/25/25)
D. brevifolia 'Morningside': had 55 seeds, so 27 for water and 28 for smoke disc (harvested 5/29/25)
24hr treatment
12/29/25
I count 5 germinated with smoke paper disc from Morningside locality. 0 for all other pots.
The morningside locale plant is pictured below.
Interestingly, this seller mentions their seeds need no treatment:

That's very interesting, regarding the smoke treatment to induce germination. I have used liquid smoke from the grocery store in the past on some species and it works just fine. 'Makes me wonder if certain regional populations are evolved to sprout after fires, while other populations aren't exposed to burning in the wild.
Good work Drosera36. I failed three times trying to germinate seed from my one Alachua plant. Yet I have no trouble sprouting seed of two other forms I have, from North Carolina and Louisiana.
While on a Florida trip I encountered the frequent fire phenomena there. I drove a long distance through clouds of smoke like a dense fog. @bluemax, I have seed for you if you’d like to try your liquid smoke on them. My one germination may have been an accidental result of having a lit tea candle near the pot.

Which species have you used that on? It certainly seems that way. I'm surprised since Drosera capillaris doesn't seem to need that. Both species can also be found in South America, I figure there are fires down there, too.
From my understanding, the entirety of the US coastal plains was exposed to fires for millenia, which would include NC and LA, so I wonder why the Alachua county plants are like this. Drosera brevifolia is certainly less common than D. capillaris around here, which may be related to their dependence on fire. At the Morningside locale, they do do controlled burns. At the CR1475 locale, a roadside, I'm not sure if there are controlled burns. But there must be if they germinated there.
