Nice pictures Sean, thanks for sharing them. To radjess331: I think that depends on your climate and the reaction of the seeds. Maybe it will be worth a try to sow some of them even now, to see if they germinate or not. I found it always surprising that the seeds sown here (at the hottest spot of Germany with nearly Mediterranean climate) between June and August (in different pots), started germinating all together in October/November when temperatures started to drop clearly beneath 10 degrees centigrade during the night. During the day even in our cold greenhouse approx. 20 - 28 degrees are not rare at that season.

Hey Folks,
I'll emphasize what Phill Mann has said, and that is if you're trying to grow D. glanduligera, don't worry about the soil mix. Plants in SW Australia will grow on an old sock if given a chance---they don't care a bit about soil type.
The mysterious reason this plant doesn't grow well in cultivation must be for some other reason---perhaps the feeding issue as others have suggested, or seasonal temperature requirements?
Cheers
Barry

As shown in our Drosera documentation: providing protein either by living spring tails or feeding with crushed fish food flocks, is an essential point to keep the plants alive and even flowering, however, I am sure that there is an additional need - which we did not find out until now - to achieve big 2 inch plants with a rich seed production in cultivation.

okay then i will try to grow the seed..... i wont have to worry bout prey items round my house....with all the rptiles i have they attract insects.... i probley will feed my plants if i get any to grow mashed wax worms cause that makes my herps happy so my thinking is this herp+insect=bigger herp+wax worm= happy plant+insect=bigger plant+wax worm=happy

Hey Folks, I've been germinating ICPS seedbank Drosera glanduligera because I want to play with their snap tentacles. I've tried this plant in the past, and when they get to about the fourth leaf they would die rapidly, sometimes first making a dinky inflorescence. Any suggestions on how to get this plant to survive? Barry Barry, I have gotten them to germinate I don't think I had that many make it as the pot was under shade but not out of a place that rains. I think I may have lost many of my seedlings. I have them now inside a greenhouse and under the bench. I have not really fed them, but I can see many collembola hopping around. These seeds were sown in august of 2008. I have sort of begun to wonder if live Sphagnum, as it seems to be the preferred medium for so many CPs, is providing other things than just a substrate. I have suspected it might provide food (many macroscopic and microscopic inverts) and biological activity that helps to break down seed coats thus hastening germination. Mach Fukada Added about one month after the above pic. now about the size of a quarter. I can see the start of an inflorescence. Also can see in the concave portion of the leaves piles of black gunk that appears to be digested springtails (collembola). MTF

I am happy to report that it was possible to make good progress with the cultivation of D. glanduligera this winter. Very cold nights, good light and a better way of feeding helped us to grow them nicely. Meanwhile they flower and I was able to make some very detailed new microscope shots of the unique snap-tentacles, which can be found here: www.hartmeyer.de/bilder_glanduligera_0209GB.htmHere just two photos as appetizer:

Hello Siggi,
Congrats on your success with this wonderful species. Out of 53 seedlings, I've managed to keep 4 of them alive and semi-healthy, but nowhere near as nice as yours!
They do seems to like it very cold and seem to grow best for me, with cool days around 70F and cold nights down to 35F. I've even left them out in freezing temps with no apparent harm.
If grown in sphagnum live or dead, the moss actually helps to supply a myriad of small insects for food, if left outdoors it seems...
Happy Growing,
Brian.

kulamauiman, very impressive how large your plant is. It's almost as big as my D. burmannii! How tall of a pot are you using?
Siggi, i love the pics of the flowering plants. They look great. Also, microscope shots are neat. I never realized that the snap tentacles had those dinky drops of dew on them.
This species doesn't seem so bad after all...as long as you feed them. I noticed that basically every leaf on the above pictures has food in its trap. Feeding my D. burmannii and D. indica has made them grow 4x as large as they were before. It's definitely the trick for the annuals.

That is no dewdrop, all snap-tentacles are non-glandular. It is a ball to pear shaped cell-structure which is part of the trigger mechanism. There are three types of marginal tentacles (MT), of which two are real snap-tentacles: MT Type 1 = symmetrical glandular head with mucilage (i.e.: D. scorpioides, D. macrantha). MT Type 2 = bi-symmetrical none-glandular head (i.e.: D. burmannii, D. rotundifolia) or the basal rosette of D.cistiflora (picture below). MT Type 3 = bi-symmetrical none-glandular head, tentacle with snap-mechanism in 0.15 sec. (only D. glanduligera). Our definition (MT T1-T3) has been published 2008 in DAS TAUBLATT and in Stewart McPherson's Glistening Carnivores.

Dear CP-friends, welcome to experience the unique D. glanduligera on YouTube: 1. Flower opening 2. Movement of glue-tentacles 3. Movement of snap-tentacles 4. Speed contest with Venus Flytrap Videos on other CP-topics will follow.

Mach, your plant looks very robust- looks like you'll have plenty of seed with the other flower stalks that are forming as well.
Siggi, nice videos. i really liked the flower opening up in time lapse
