Cibotium barometz from Thailand. A view from above
the first pup appeared recently.
The first frond under the sun and not under a LED lamp starts to unroll)))

Re: My ferns (Cyatheas, Cibotiums. Dicksonia, Platyceriums)
Hi, Stan! I think that сooperi "tomentosissima" is obviously сooperi "tomentosissima") Two medullaris are also for sure true medullaris, because my own sporlings of medullaris (spores from NZ) are completely identical and all have distinctive characteristics of this species. As for C. robusta I can't say anything definitely. It looks similar to my 3 cooperi "Brentwood", but the scales are more brown and not so dense. I asked a question about my 'robusta" in this topic in April. I want to believe that it is true robusta.

Re: My ferns (Cyatheas, Cibotiums. Dicksonia, Platyceriums)
two of my three Cyathea cooperi "Brentwood" (from Ireland). They still look underfed. I repotted them few weeks ago, but the new fronds in the new bright and sunny conditions only start to grow.

Cyathea cooperi "tomentosissima". All 3 ferns grow very well.

Re: My ferns (Cyatheas, Cibotiums. Dicksonia, Platyceriums)
I saw a photo of Cibotium schiedei ( I will NEVER remember how to spell that tricky last name- thanks google!) not even identified,but I knew what it was in an article about tropical gardening. It had a fat short trunk- 4' maybe more and big lacy fronds. Under it were broms and a Thai stone head with grassy plants. What a great and simple corner of that garden. Mine hasn't reached the large frond size I expected..better since being in the 32 gallon Rubbermaid..but not the wide spread. I guess I haven't lavished all the water that fern needs on it.

Re: My ferns (Cyatheas, Cibotiums. Dicksonia, Platyceriums)
I never tried to grow any fern from spores. Congratulations! It will be e and is a nice collection.

Re: My ferns (Cyatheas, Cibotiums. Dicksonia, Platyceriums)
Thank you! My only one Cyathea robusta (with Cyathea cooperi "Brentwood" to compare).

Re: My ferns (Cyatheas, Cibotiums. Dicksonia, Platyceriums)
Alberto, I bought these Cyatheas as young sporelings. All my own Cyathea sporelings are still unadopted to the normal humidity. I started adaptation with Cibotiums. First 15 Cibotium regale sporelings are done. I'll post some pictures later.

Re: My ferns (Cyatheas, Cibotiums. Dicksonia, Platyceriums)
I can't garantee that my plant is robusta. I asked about it in this topic. But how it is possible to compare the plants of such a different stages? Your plant has soft juvenile fronds. Mine grows under full sun half of the day and therefore it has rough fronds. I don't have pictures of my plant of the same stage. I got it when it was few months older (from the USA). Maybe you have older plants?

Re: My ferns (Cyatheas, Cibotiums. Dicksonia, Platyceriums)
Hi Alex, After a clearer comparison with Mario his photographs and mine I also think now that you have no C.robusta! Your earlier pictures also show brown hair in combination with white hair, young C.robusta only have white hair, Sorry for the earlier analysis, always hard, a small deviation at young plants can make a difference Eduard.

Re: My ferns (Cyatheas, Cibotiums. Dicksonia, Platyceriums)
You've built a fantastic collection of some of the best Ferns to have. Are you selling them? Growing them to give to a local greenhouse botanical garden in Russia? Years ago I was sent kindly by a GOTE member spores of C.howiana. My wife thought it was junk mail..out it went. She also is the one who tossed a dozen Cycad - Macrozami seeds out when I wasnt looking. I should buy a mansion...to give me room to hide my stuff

Re: My ferns (Cyatheas, Cibotiums. Dicksonia, Platyceriums)
Sorry for the late answer. I still have some hope that my plant can be a robusta))) As I said I don't have pictures of my plant at the same juvenile stage. I got fully adopted to normal humidity plant with all young fronds rotten in parcel (after two weeks in the closed box). But I also have strong doubts))) Actually I had them from the start. I noticed that the scales on this plant fall down after a small touch. You can lead a fingertip across the frond and it become bare. All the other Cyatheas in my small collection have much stronger scales. "Are you selling them? Growing them to give to a local greenhouse botanical garden in Russia?" I didn't try to sell any treefern yet. Some people here ask me to do it, but the plants are still too young. I doubt that I will be able to sell all the extra plant by reasonable price. Not many people can afford the growing of a giant treefern in our severe climate. The best treeferns for selling are D. fibrosa and D. squarrosa. You can grow them on the small heated balcony for many years. I got most of the spores in the local botanical garden and I promised to give them some sporelings (I gave them already 15-20 plants of Cibotium regale). The botanical market in Russia is not so large as in Western Europe. And I never tried to send plants in international parcels. It is officially prohibited, but as many things in Russia is possible to do with only some risk to loose the plants on the customs if the parcel is cheked. So the only main reason for growing treeferns from spores for me is to form my own collection. Now I try to grow spores of Dicksonia herbertii. I got them from Australia few months ago. Now I have the green carpets of gametophytes in two containers. The spores germinated very well. I'll post the pictures of my first adopted to normal humidity Cibotiums later. I "invented" a new method of fern adaptation (I think it is new only for me). I put a sporeling in the separate pot, cover it with a transparant plastic bag, make a small hole above the apex, and lower the hole to the ground level letting all the new fronds grow in the normal humidity. The adaptation takes only 1-2 months. When 2-4 new fronds are grown you can remove a bag without problems. The only problems are that you should help some fronds to find a hole and it is harder to monitor the soil humidity. This method was "invented" by my sporelings themselves ))) Some of them grew new fronds through air ventilation.
