Seeing this lovely image of Pauls the other day got me thinking how wonderful nature is, and what beautiful things can be found in seemingly harsh conditions.
1.


Here are two photo's I took this summer in England. The first was growing from under limestone rock in North Yorkshire. I think it could be Ajuga reptans?
The second, Sea holly, Eryngium maritimum on the beach at the North Walney Nature reserve.

Plants are so resilient, and can grow anywhere it seems, you only have to look at the cracks between pathing stones to see a dandy lions and moss etc growing happily.

The plant in photo No.2 has been identified by Paul M as "possibly" self-heal, Prunella vulgaris, I tend to agree now I have checked it out. Excellent, something else I have learned today .

[paul m]

I said that I thought it was self-heal.

It's an interesting point you've made - relates to a lot of deep ecological thinking One theory is that the greatest diversity of species is in habitats with intermediary levels of disturbance and/or stress. i.e. you don't get many (or any) plants (insects &c &c) at the extremely stressed sites (deserts [hot or cold] &c) but in the stable, climax habitats (e.g. forests of various kinds) there are also not many species - go and count the numbers of species of plants in your local semi-natural woodland and compare it to what you find in gardens (cheating ), heathland, ancient meadows ...

By one calculation, the Australian scrublands are the most species diverse in the world .... others would be coastal dune systems (as you, Goosey, will know), maintained heathland, limestone grassland - partly disturbed but not enriched chemically.

One fortunate thing is that most of these places are useless for housing or agriculture .....

This is a pretty harsh place, corner of my balcony: Sedum dasyphyllum like S. anglicum, but leaves opposite!

I think I shall take this as a compliment!

It looks very much like Self-heal to me now I have checked it out, but point taken I shall edit my post .

It just goes to prove the point Eric, a good example! Just looking at the thumbnail it looked a bit dubvious but it is a pretty little plant .

Bare calcerous sandstone. Amazing how anything can grow here.
Anyone any idea what it is? I can't find a sedum with transparent petals.

[paul m]

I'm always struck by the numbers of trees growing on roofs in Sheffield - usually birch or, in this case, Buddleja davidii. [In this case I think the crow was waiting for a forest to grow ... ]


But possibly the strangest thing I've seen is this Erinus alpinus - as its name implies, should be in Eric's neck of the woods but in fact was in lowland Northamptonshire!

No don't recognise that - the flowers actually look quite papery .....

[ericrovve]

I have Erinus alpinus as introduced into Britain. I haven't found it here yet, but it's supposed to be around. Re the sedum(?)Lost a bit of quality in uploading. They are actually semi-transparent petals.

Getting back to the urban ecology topic. Railway lines and goods yards provide some very interesting habitats for plants and insects when
they fall out of service. The substrate (I hesitate to call it soil) is well drained and entirely mineral so the closest natural systems are dunes or volcanoes! You get a very interesting list of invertebrates and plants - it was on a siding deep in coal dust that I discovered the first British Zodarion italicum (presumably fell off a train and thought it was near Vesuvius?).

This picture is of Templin station in eastern Germany where railway services are being cut (it's the same the whole world over?) and in five years there are seriously sized saplings as well as all sorts of other plants taking the station and sidings back into a "natural" state ....

[I should note that the railway is still running - a small diesel unit every few hours from Berlin. It is a very good area to visit even for its farmland: farmers in the former DDR couldn't afford western pesticides so there is far more wildlife about .... for the moment .... ]

We often talk about loss of habitat to human activities but sometimes nature finds its way back. This is a picture from Padley Gorge a local beauty spot and site of scientific interest (primitive oak forest - the trees growing out of the rocks on the left are older than the ones growing out of the track on the right).


The track interested me because it had obviously been used by horse-drawn carts.
At the end of the track:

A quarry used for production of mill stones (these are the eponymous millstone grit measures of the Carboniferous - Pennsylvanian era). For centuries stones were carved out of these rocks both for flour mills and later for sharpening tools in the steel industry and then, one day, it just stopped ... leaving some stones almost ready for use but unwanted ... and nature returns!

Such an appealing image isn't it!
Nature really has reclaimed this - it looks so natural even with the millstones (I am sure I could make use of one of those in my garden ).
I doubt we will be so lucky in future.

Another example of Buddleja growing in unusual places. It must be one of the most tolerant species and yet it seldom becomes an invasive plant out-competing other species.

I suspect it's what used to be called Polygonum baldschuanicum but is now Fallopia baldschuanica - Russian Vine.

wow. i appreciate this so much.

BTW, new here!

You're very welcome! let us know some more about yourself.

Recently went to another, nearby, more and came across this:


I can understand people leaving the millstones but this seems much more valuable and, if it was a horse trough or such, almost completed?
Would make a very nice container for garden plants!

I saw this plant growing out of the Dom when I was in Utrecht the other day.
The Dom is a gothic cathedral dating from 1254 and its tower is the highest in Holland. The most significant thing about this cathedral is that half of it has gone. The ship collapsed during a tornado in 1674. The surviving part has not only survived the tornado but also the Reformation.
It seems amazing that a cathedral that has such a rich history and has survived so many 'battles' can't stop a little plant from growing out of it...
