Ferns 2017

Fascinating Rick, and lovely to see exactly where it lives.  I wonder where the next nearest colony is?

[ChrisB]

I got three new ferns this year. The one on the tophad the label athryum felix femina Dres Dagger, the middle one had a label of triple crown and the one on the bottom has no name at all.  If anyone has views on what these are I would be grateful

Fascinating Rick, and lovely to see exactly where it lives.  I wonder where the next nearest colony is?

Kenton Seth (from Colorado,USA) was here on a very cold March 17th day, and I took him out to see some the wild areas here.  This is him examining the same rock. Arrows point out a few of the plants, since they are dried up and brown for the winter.  This is the only place that I have seen (so far) where the fern grows with no visible rock fissures.


Technically, the nearest ferns are on the next hill over, on a vertical rock face.  The first rock is west facing.  This one is east facing.


But I think the next place is about 30 miles away, again on a clean rock face of a gorge cut by what was once a raging river (now a creek).  This is the same kind of limestone, sort of like tufa: very hard, yet more porous than a limestone that is quarried.

I like this fern particularly... then he gets over the deepest frost and the biggest heat. Cheilanthes fendleri from Arizona. He stands with me in the full sun and is absolutely resistant to heat and dryness. And the new desires show nice strong hairs.

It looks terrific. I've never had much luck with Cheilanthes, grown several from spores but they don't thrive. You obviously have the touch.

Asplenium trichomanes and Asplenium scolopendrium: both growing on my house.

Giles when I park up to collect the grandchildren from school both those ferns are growing happily in the school walls along with Ruta-maria.

Shelagh,
I've only seen Asplenium ruta-muraria on brickwork, locally, but I keep on hoping...

Hi Chris, they look like variants of Athyrium filix-femina 'Victoriae', spores raised from this variety give forms such as these.

Thanks Anne!

Cryptogramma cascadensis, Cascade Parsley Fern.

Does anyone cultivate this species?

This species has a considerable range in the western U.S.A. however it seems somewhat unknown. I am curious as to its cultivation status.

Possibly not very easy to grow, Cryptogamma crispa in the UK is reputedly very hard to cultivate thaough it grows like a weed on the slate spoil heaps in north Wales, as well as its natural sree habitat.
