Rock ferns

[Hans A.]

Olga and Zen, your pictures are fantastic!

Here a picture of Ceterach officinarum together with Polypodium cambricum in the local mountains taken last weekend.

Although Adiantum capillus-veneris(?) is evergreen the fronds are lying on the ground now due to the heavy rain the last weeks.

Adiantum capillus -veneris should not be hardy where you live, yours is Adiantum venustum, a great and easy fern to grow.

I am not sure what this one is. It is evergreen and has an underground creeping rhizome.

Blechnum penna-marina?

To me it looks a little too loose and not hard enough for penna-marina which, by the way, is not terribly hardy here. It does live in the southernmost part of Nova Scotia.

Polypodium virginianum is a neat little native rock fern that grows even on boulders here.

Thanks everybody.
It is growing in shade and the fronds is quite hard. Actually I had thought of B. penna-marina myself.

Hans, you probably are right

Thank you all! 

Well, I am not sure but probably because i haven't asked and you do not have my address!?

Trond, I am afraid we are not allowed to send/receive seeds, spores or plants from/to here.  I send seeds occasionally when go abroad. It happens not as often as I want.

OK, Olga, what a pity! I wasn't aware of that.

[Olga Bondareva]

yours is Adiantum venustum, a great and easy fern to grow.

Yes! I grow it for some years and it runs between rocks quickly.

What a great series of pictures! Razvan: we are very cold here, often with temps below -20C. We have just had a month of snow cover, but it is now melting and the garden looks good coming out of the snow!

The Adiantum venustum is excellent for us as well. There is A. capillus veneris in Colorado (and further north) but always near warm water (hot springs and suchlike).

Wish we had as many ferns as I see on my trips to Europe: we have nearly 70 species in Colorado, but most are very local or rare.

Olga, do you grow some of these ferns in your garden?

If you are interested in hardiness I have the info that the tripteron survives well since ten years here in mid-Sweden (Örebro). A surprice since it originally came from just north of Kyoto. I have never looked for spores but I will if you ask me.

Yes, I do ask you, Göte, will you look for spores

I gather spores sometimes. You know why I don't send them. 

Well, I am not sure but probably because i haven't asked and you do not have my address!?

I will but pls remind me in June

Adiantum venustum is hardy here in Minnesota (USA), zone 4a, too. 
Even with unreliable snow cover.

[Hoy]

OK, I've solved it!
I once grew Adiantum capillus-veneris for several years but it succumbed to death in a cold winter. Later I got another looking similar from a friend but it has withstood the bad winter last year - but it has to be A. venustum 

This winter so far has been so mild that I could have grown oranges in the garden

[Hoy]

Two ferns from last summer - and not in my garden! However, I wouldn't mind growing them but I doubt that they would survive for long!

The first is unknown (suggestions?) and is from the foot of the mountain and the other ( Blechnum schomburgkii) stood in the lee of the highest peak almost forming a forest!

Edit: from Venezuela, Roraima tepuy.

Trond first I wondered what strange ferns grow in Norway. Now I understand images are from South America aren't they?

Oh sorry,I forgot to write where from! Yes, it is Venezuela.

Olga, your pictures of Adianthum venustum are much better than mine

[Tim Ingram]

Trond - that second picture looks like a botanical wonderland! Are there any books on the flowers of Roraima? Your earlier images were really exciting too.

Tim, I have looked for books but not found any. I know there are several floras of Venezuela but I have never seen any for Roraima or the other tepuys. Should be!

Trond
I wouldn't wonder if fauna of Roraima included dinosaurs... 

Here are some more ferns. Pictures of previous years.

Onoclea sensibilis isn't alpine of course. Very suitable for pond banks.


Onoclea sensibilis Dwarf.
