Alpine rock-cress or Fjellskrinneblom in Norwegian, Arabis alpina in Latin.
Found this little plant in the mountains between Troms and Sweden, near the Rosta hut, around 700 m. Fantastic to see how it can grow right out of the stones, though there probably are some loose gravel in between. It was quite small, app 7-10 cm.

From Wikipedia:
"Arabis alpina (Alpine rock-cress) is a flowering plant in the family Brassicaceae that grows in mountainous areas of Europe, north Africa, central and eastern Asia and parts of North America. In the British Isles, it is only known to occur in a few locations in the Cuillin Ridge of the Isle of Skye.

The stems of A. alpina grow up to 40 cm (16 inches) tall, and are topped with loose heads of white, four-petalled flowers. The leaves in the basal rosette are long, strongly toothed and clearly stalked, although the stem leaves are stalkless and clasp the stem.

A. alpina grows in damp gravels and screes, often over limestone.

A. alpina is believed to have originated in Asia Minor about 2 million years ago. From there it migrated twice into East Africa (500,000 years ago) where it grows today on the high East African mountains in the ericaceaous belt. Another migration route lead A. alpina into Europe which was then colonised periglacially. In genetic terms, the highest diversity is found in Asia Minor. In central and northern Europe, A. alpina seems to be genetically quite uniform [1].

There is growing interest to develop Arabis alpina as a model organism for genetics, population genetics, and molecular biology. The first genetic linkage map has been created and the first phenotypes, especially perenniality, are tackled by QTL mapping."

great pic, is it always so small? Its close relative - Arabis caucasica is a much larger plant.

Hello Jon

Another beautiful Alpine wildflower.
Just marking the post for now

Rob

Very fine image of this plant, good contrast and POV, good DOF....very nice indeed!!!

Hi Jon,
A very pretty flower caught beautifully in its surroundings.Quite amazing how it seems to grow out of the stone.Nice handling of the contrasts keeping the petal white.Good DOF and detail.Well done and TFS.
Regards, David

Hi Jon,
A beautiful bunch of flowers. You have captured it very well with excellent details. Thanks a lot for sharing.

Hi Jon,
Beautiful flower. Delicate presentation. Thanks for sharing.

ps: Any particular reason to include that small plant in the bottom right corner of the frame?

Very beautiful photo indeed! Life will get a hold on the most impossible places. Thanks for presenting Norway in such a wonderful way!

Med vennlig hilsen Torbjørn

Hei Jon,
I like the composition, showing so well how this little plant is able to survive in a hostile environment!
Good diagonals in the composition, the delicate flower is captured with fine details!
Greetings,
