A Puzzling Fern

Hello Ferners, The fern pictured below I bought as Dryopteris wallichiana, but it certainly does not look like the rest of wallichianas I am growing. In many ways it is very similar .
But it has much fewer scales, a smaller size( same growing conditions and age), deeper venation and is less upright, but only slightly so. Asked a few fern experts here,( Seattle,WA , USA) and they were puzzled. I thought maybe D. yigongensis, though it is very rare in the trade here. Any way I am hoping you will be able to shed some light on this mystery.

Thanks for looking,

Daniel Mount

Asplenium ceterach

On our way from one Dryopteris aemula site to another, we stopped off to see the progress of Asplenium ceterach on this railway bridge. This bridge was renovated by the Railway Authority and in the process all the plants were removed and the pointing redone. We were pleased to see that despite the best efforts of the Railways, Asplenium ceterach seems to be able to cope with this treatment and even created new sporeling

Dryopteris aemula sites in the New Forest

Following new sightings by Alison Bolton and Mike Rowe, Ashley & Jo Basil and myself went to see 2 new sites for Dryopteris aemula in the New Forest
The first site was in Brately Inclosure which, at first sight, seemed an unlikely place
However we found, within an area of some 200 x 200 yards, about 200 plants looking very healthy

The next site we went to was Norley Inclosure, where we found possibly 10 plants

This brings the number of sites for Dryopteris aemula in the New Forest, known to us, to 6

Botrychium lunaria in May in the New Forest 2020

Ashley & Jo Basil and myself, went back to check out the Botrychiums at Appleslade Bottom

We found about 50 plants
They grow in an “open” field amongst bracken
A lot of the bracken seemed to be suffering from a late frost, which helped us find the Botrychiums
It is not probable that we found them all. This is around the same number for previous years but they seem to moving lower down the slight hill
I have included a picture that I hope explains our numbering methodology
These are bamboo kebab spears, 12 inches long, to which I added some red sticky tape at the top to make them more visible
We put one of these next to each plant and then when we have had enough of searching, we collect the “spears” and count them

We also found about 12 distinct colonies of Ophioglossum azoricum in 3 different areas

Lygodium japonicum

My Lygodium japonicum often looks a bit tatty with all its leaves turning brown, so I assumed it was effectively deciduous and would regrow from the ground each year. It has been my habit to cut the plant right back to the ground each spring. This year, the bottom half of the leaves have died back but the top half of the plant is still green, if a little “battle-weary”. I noticed that there are a few small “shoots” starting off on the “old” wood. The one in the picture is right at the top of the plant. The plant is also putting up fronds from the ground. We had a relatively mild winter this year for the plants with the coldest tempreature I recorded being -4C

Tree fern watering Support

At Harlow Carr we have been in the middle making an Exotic garden full of great foliage plants, it will also serve as a Secret Garden with lush plantings, a small glass house and arches for vines to grow with a winding pathway that takes you through it all. Among the plants will be some Tree ferns with some great mature trunks that will gives that mystery and adventure a Exotic garden can have. However with this lack of rain we have been receiving over the last couple of months we are a bit worried they may be in a bit of a shock. So Horticulturalist Russ Watkins came up with the idea of wrapping the trunks with hessian fabric to maintain a bit of the moisture and also keep them cooler. This also helps when there is a high demand for other plants needing water at the moment around the garden and a small task force at hand. So far so good and they seem to be maintaining their moisture, fingers crossed!
