The plant seems to me as a form of D. burmanii, in which case, the flowering process could end up killing the plant and you would need to replant the seeds to get it again. But, I'm not completely sure of the species identity

thanks for the heads up. I cut the stalk off.

If it is D. burmannii which is what it would appear to be, removing the flower stalk may make it last a little longer but the plant will still die... It is a short-lived species easy to propagate from seed. The way to keep it is to collect and sow seed as required.

But, I'm not completely sure of the species identity This may be standard horticultural advice, but backward for this species. First, the plant looks like D. burmannii, but the flowers are usually white... Regardless of the particular ID, this plant is short lived, so the only way to keep the plant long term is by letting it flower and collecting the seed or letting them fall where they grow (self sow). To me, it is better to start a couple of fresh pots every year or two. This kind of sundew can just up and die without flowering and then you don't have any seed... The flowering and setting of seed do take nutrient and energy. Give the plant a very steady diet so it doesn't fade while producing the next generation. Once on a good diet, it will not stop flowering for a season. I see, it looks like you have been feeding it, but these species, D. burmannii, D. sessilifolia and their hybrid are quite ravenous little beasts!

Well, then good to know that it is better to have the flowers then, as I only have 2 plants at the moment, anything could go wrong with what I thought and I would need to get the seeds all over again. Thank you guys for clearing that mistake.

In spite of popular opinion, Drosera burmannii plants can be grown long term and you can collect seeds from the plants if they are very healthy and you feed them well. The plants in this photo just finished supplying 50 packets of seed to the ICPS Seed Bank. (There is one more scape of seeds left almost ready to be harvested.) The plants are 5 years old and have been cleaned up and repotted once. This is the "Pilliga Red" variety with pink flowers. You can see a picture of the flower at www.carnivorousplants.org/howto/GrowingGuides/D_burmannii.phpI realize the species description of Drosera burmannii says the plants have white flowers. Robert Gibson has confirmed there are pink flowered populations in Australia but he regrets he doesn't have enough spare time to do a proper scientific treatment of the plants. This is a good opportunity for McPherson and company to name another variety in their new Drosera book. As far as keeping them long term all you need to do is feed the plants regularly, avoid temperatures too warm or too cold (exactly what is too cold or too warm depends on the source population), and keep them wet. They will accumulate a large amount of old leaves so the plants will need to have the leaves cut or carefully pulled off and be repotted in fresh soil about every three years. I do grow my plants under lights with constant photoperiod and that may also help. Here is an example with Drosera sessilifolia of what happens if you ignore the plants and let them produce seed. These plants can be saved. They need to be fed a bit more, then they can be repotted. These plants are 4 years old and have been producing seed for the Seed Bank.

I agree with John- I've seen populations of D. burmanni in the Kimberley region of Western Australia (including several pink flowering forms) in which individuals have persisted for several years, and often have up to a dozen old scapes alongside the new season inflorescences. They are certainly not an annual when grown under the right conditions.

Thanks for all of the help, not only in identifying but also in care and longevity.

"so the only way to keep the plant long term is by letting it flower and collecting the seed or letting them fall where they grow (self sow). " Mhmm are you sure ? leaf cutting propagation each summer like i do is impossible ?

Mhmm are you sure ? leaf cutting propagation each summer like i do is impossible ? Tell us more about your leaf cuttings. "Everyone" has always said don't bother. Do you get one plant per leaf like Drosera spatulata or lots of plants originating in the central part of the leaf or lots of plants at the edge of the leaf? How do you start them?

Yes, please share on your leaf cutting techniques, for as far as I know, cuttings with burmannii and sessilifolia only rarely, if ever, work. Also, are you sure your burmannii are actually burmannii, and not hybrids with its relative? Burmannii as a species have lighter pink to white flowers than the pink flowered sessilifolia (with rare exceptions like Piliga Red), and the hybrids appear to be fertile as well...

There are a lot of places being collected from that are new. When new locations/things are collected, we get more information.
