[I am not sure if this is the right place to post but I couldn't find any more suitable place. Please move if necessary.]

I have been experimenting on growing 3 sp of erios and 1 sp of xyris from seed for the past year and so far all attempts have failed. What I am trying to grow are :
1 . Eriocaulon cuspidatum
2. Eriocaulon willdenovianum
3. Eriocaulon fysoni (this one I am not convinced it's really E. fysoni. I only found one reference on internet)
4. Xyris operculata

Here you can appreciate how small the seeds are:

This is the 4th attempt:

There are many possible reasons why previous attempts have not worked, such as seed viability, temperature, soil etc etc. However, this time I talked to a botanist based in Thailand who is specialized in Eriocaulon. I was advised to heat/dihydrate the seeds up to 60C during 3 days. Then prime the seeds with a 0.2% KNO3 solution during 6 hours which I did. I didn't go through the dihydration process as my seeds have been sitting in a box on top of my aquarium light for quite some time so I guess they are probably pretty much dehydrated by now. I know these seeds can take 3 weeks or more to germinate so now it's a waiting game. Hopefully this time it will work.

If anyone has had any success in germinating these specific plant sp. please let me know.

I will update the thread when necessary.

the guy from aquatank sells these seeds pretty often. might be worth asking him.
not sure if you've seen this link either
anyway the one that stood out to me is xyris operculata. I considered getting seeds of these considering the xyris family is mostly aquatic, however I didn;t because I was unsure how they'd look submersed. do you know how they look?

Yes I know that link and a few others. In fact I have grown other Erios from seed but this specific sp I mentioned I have been unsuccessful so far. I am wondering if the seeds are viable actually.

No idea how they look submersed, this is purely experimental. I am not even sure if they can survive submersed.
In the past I tried growing some Xyris sp. from the south of Thailand. They survived for a while in my tank then died.

care to show the other links?

as for the xyris please update this thread. am very interested in getting some xyris, but don;t feel like paying crazy amounts lol.
anyways, I don't think I've seen a picture of your tank, I'd love to see some!

Missed your post.
  • Ebay was one. There was one seller from Ukraine that provided instructions in details. The store name was AquaTank but seems he is not selling anything anymore so nothing to be seen there.
  • The other one was this: Всё про эриокаулоны
That seller in the Ukraine is Alan Yusupov I think....if you're on Facebook you could try messaging him on there.
He's on my friends list and is active on there at the moment although with the current situation things may be difficult for him.
