Unknown fern

[Hoy]

Blechnum spicant, I reckon.

B. spicant
I thought of that too - it is one of the commoner ferns here - but I've never noticed that wide rosette of any B. spicant here.

Graham, you must solve this

Link to  nice pic of the B. nipponicum, Trond.
It shows what I was trying to say... that the B. spicant leaf is linear while the  B. nipponicum leaf is lanceolate, fatter in the middle section.

Some lovely plants on that site, Trond.  I won't be buying plants from Japan but it's nice to look.
Pusatilla sugawarii is fantastic.

Hi Trond,
It is the wide rosette that made me wonder in the first place. I can't find any spicant photos that show it quite as obviously as does this one. But I can see what Maggi is saying about the leaf shape. It hasn't increased in several years either and I think that spicant increases quite quickly doesn't it.
The person I got it from hasn't bought any nipponicum so it can't be that.

As well as being fatter, don't nipponicum leaves have more movement in them? The spicant ones are kind of stiff.

You have the fern growing very well , at a bit of an angle, in a confined space of the trough - would that not impact on the way it grows?

Yes you are correct Maggi it was gently manouvered into a hole in the log, and is growing on a verticle plane and that might have some effect on it.

Some pix here which show a rather circled growth and a pic of the reverse of a frond... may be helpful?

Thanks Maggi,
I will have a closer look tomorrow, its a bit dark outside at the moment

I ordered some plants from them last autumn. It took exactly 1 week from the plants were shipped till I had them in my hand at home!


Maggi, I agree that the fronds are very similar to spicant.

[Graham Catlow]

Well, I've had a good look and I think from the photos the conclusion is it has to be B. spicant

Thanks Maggi and Hoy for taking the time to investigate.
