D. burmanni seedlings & ?
« Thread Started on 11 Mar, 2008, 15:21 »I'm new to this forum so first off, thanks to you all for all the info you have shared with me, without ever knowing it!

I live on an island off the East coast of Thailand and found this site mainly due to my interest in Neps...but I often cross paths with other plants and before either of us knows it, they are breeding right here on my porch! Such was the case with some Drosera burmannii. (OK, I said "Drosera burmannii" - but that's just my guess! Please correct me if I'm wrong!)

I've been trying out the germination of Drosera burmannii seeds from some older plants that I decided to let flower. Thanks to all the earlier comments on procedures on this forum, I'm quite happy with the progress so far. The "seedling" boxes were planted on Feb. 19th and the first germination (that I saw) was by March 5th. Since then I see a couple new ones every day.

The larger seedlings (transplanted in rows) are volunteers that came up in the muck of the old parent plant pots.

And now, can anybody identify these little guys for me?

And these may just be a big clump of D. burmannii seeds that all fell together in one spot? Or? What do you think?

Okay, thanks again to everyone!

The unknown sundew is D. indica. Link to Post - Back to Top Loggedtarence

« Reply #4 on 11 Mar, 2008, 17:28 »Tarence and Cindy - Thanks! Hmmm, D. Indica... S. African species aren't they? I wonder how they ended up over here in Thailand? Some time back they (The D. burmannii) came to me along with some Nepenthes from a grower in Southern Thailand. I noticed 2-3 plants less than 1/4" tall off to the side that looked interesting. Then while I was away kayaking in the jungle the D. Brumannii and these others flowered and then quickly faded away. I just found a few sprouting up from the mud of the old plants. Looks like yet another species has me hooked! Link to Post - Back to Top Loggedcindy

D. indica can be found in Thailand. I think the Pha Taem National Park in Ubon Ratchathani Province has them as well as D. burmannii.

Terence,
I have got no idea. Maybe, since this form is from Thailand. Link to Post - Back to Top LoggedDavid

D. indica actually is pretty widespread, it can be found across the Africa, Asia and Australia. the name itself, Indian sundew, suggests that it can be found in India. Link to Post - Back to Top Loggedlooking for different forms of N. ampullaria, N. rafflesiana and N. xhookeriana.

« Reply #9 on 12 Mar, 2008, 12:27 »Thanks for all the feedback! I have a lot to learn about Droseras.

David - Sure, I'll post more as it gets larger.

hongrui - Ok, that probably explains the variation that Tarence is speaking of.

Edmund 83 - There is no dirt under the sphagnum. I just lifted the plants roots and all and set them into the sphagnum. They were all coming up in clumps and I thought it best to seperate them while I still could! I'll see if this was a good idea or not! If anyone knows if it would be better to just set them in soil/mud or if the pure sphagnum is ok I would be glad to have guidance!

All Drosera lovers - you may have already know of these links, but I found them very useful;

shawn,

May I know what conditions did you germinate your D. Burmanii seeds?

I saw you used Dried Sphagnum moss, I am guessing pure Dried Sphagnum?

How about lighting? Full sun? Artificial? etc?

How many seeds did you sow by the way?

First off, let me say that these were my first attempts, so it may not be the best media to use just my attempt; I germinated them on very finely chopped sphagnum (at least after the first batch) by putting it in a blender for a few seconds. I had to wet the sphagnum with mist as I added it to the boxes 1 cm. at a time or it doesn't wet thoroughly. The boxes were covered with a clear lid and set in bright light (Sun) but not direct sunlight. The little boxes I used stayed moist, so I only had to re-wet them once every 10 days or so. I can't remember how many seed there were but I think about 10 per box and I tried to set them far enough apart that I would be able to remove them without disturbing the next plant. The finely chopped sphagnum helped in that, unlike the long fibers, it allows you to prick out the plants without pulling up other plantlets when its time to transplant. The downfall I had was when transplanting them... I should have hardened them off (kept them covered and slowly transitioned to open air) so I lost almost half of them. Good luck!

Thanks very much for sharing your style of germinating, this helps a lot. Unfortunately I won't be able to get away with using the blender for sphagnum moss hehehe!

Finally got my Burmanii seeds to sprout however I noticed that they turned brownish and that unfortunately the cocopeat medium I used has some cyanobacteria (blue green algae). I am wondering if burmanii seedlings do turn brownish naturally or is there something wrong? Maybe too much sun? maybe algae is causing problem? Nutrition?

Oh oh, I think we could say something's gone wrong! Again, I'm no expert on these but I've never seen a brown one that was healthy. How much sun were they out in? Open container or closed? A picture would probably help. Let's see what others say around here.

[Tarence]

arvin...nope, a browning d.burmanii seedling is not good news. check on your humidity levels. is your medium wet enough ? if they are too small, don`t expose to full sun yet.

cocopeat = peat moss ? sorry, not too familiar with that medium since i don`t use it. but your other sundews planted in it are ok ?

[arvin555]

Thanks for your reply guys, I was afraid of that. I will try to take photo soon. But my seedlings are in the following environment:

1. Cocopeat (coconut husk or is it trunk that has been grounded I think)
2. Small 3 inch container with Lid, it is more or less sealed.
3. Water/humidity is high coz it gets droplets of water all over the container and on the Lid.
4. More or less direct sunlight, though for the past few weeks we didn't have much sunlight because of monsoon.
5. There is cyanobacteria growing on parts of the surface of the medium.

The burmanii seedlings are in their own container, my Indica container, nothing at all, my spatulata doing okay but it is in mixed cocopeat and sphagnum moss (not blendered) Spatulata looks nice and green, container looks the same as what Shawn used in the photos. Luckily no algae in that one too! It is located in the same place as the other seedlings, so same lighting.

I will take photo and post soon.

Finally was able to upload a bad photo of my burmanii Please note the different color of the seedlings, some are brown, some are still greenish. The greenish ones, I hope means they are healthy, but maybe there is possibility that they are green because of the blue green algae they are sharing space with.



In Comparison the Spatulata that germinated looks healthy green:

Hi Arvin,

Cocopeat can be toxic to CP's. I have seen it used with Nep's with success but generally not with other CP's such as Drosera. This may be the cause of the problem. Maybe you could replicate your conditions using either Sphagnum moss or Sphagnum peat. Another option for germination of seeds would be perlite or vermiculite. Cheers.
