Mountain Sorrel (Oxyria Digyna): Arctic-Alpine Perennial Herbaceous Plant

The arctic-alpine plants have changed significantly due to climate change and the Pleistocene ice ages. Oxyria digyna (Mountain Sorrel) is a widespread arctic-alpine perennial herbaceous plant found in tundra habitats throughout the northern hemisphere.

It includes Eurasia and almost all of Arctic Native America, as well as the mountain of southern Russia, southern Europe, the Himalayas, and western America.

The macrofossils dated to about 3 million years ago have been found in the Canadian Arctic. It grows in various mesotundra environments, including ruins with small or no development. Let’s find out more about it!

What is a Mountain Sorrel?

Oxyria digyna (mountain sorrel) is a perennial herb of the family Polygonaceae. Sorrel is a Greek word, and it means sour. It is a truly “good” arctic plant, differing from the place in the leaves’ size and the inflorescences’ height.

Mountain sorrel may give one or two leaves to the intrepid alpine wanderer. This tasty and hardy plant grows through the tip of a strong and durable root.

Anyway, there is some considerable difficulty regarding this plant. It is unsuitable for hybridization due to too many small delicate flowers in its inflorescence.

Why Is It Called Mountain Sorrels?

Both flowers and other plants that thrive in the arctic usually have specific unique properties that let them withstand cold or heat. Also, it allows them to survive in extreme situations where other flowers would not have the slightest chance.

A mountain flower is rare and beautiful because it grows in little water and rocky soil. Also, it grows in conditions that seem tough to live at such heights and places that remain frozen for a long time most of the day. Nature has created flowers that may thrive in such situations, so these are more special.

Plants that survive in those conditions form roots that run between the rocks to withstand the site’s humidity when the ice melts in summer. Moreover, the roots absorb water and let it bloom again.

Another feature you can see with the naked eye is that the plant grows very close together to protect each other. Their leaves, stems, and flowers have tough fluff. Also, they develop roots to grow even in open places and use low residual soil moisture.

Moreover, roots allow flowers to bloom in the summer each year when the conditions are more favorable. The sorrel growing in the mountain has the same characteristics as mentioned above. That’s why it is called a mountain sorrel.

Where Do Mountain Sorrels Grow?

Most tundra floras are established in the northern hemisphere and are mostly recognized in North America and Europe. It has a regional arctic-alpine allocation with a wide geographic range.

Anyway, mountain sorrel is located in the arctic tundra at 83°. In terms of North America, it is available in the south, near Arizona. There are only two species of the genus Oxyria worldwide.

Mountain Sorrel

Another species Oxyria sinensis, grows in the Himalayas. On the Norway coast, mountain sorrel was discovered in a 12,600-year-old soil layer.

Therefore, it is one of the first plants in the Ice Age glaciers. Yet, another riff is that this species survived the Ice Age through small areas exposed to ice.

How Long Does It Take to Grow Mountain Sorrel?

Generally, mountain sorrels are propagated with seeds. Seeds are sown in the spring and germinate 14 days after planting, and within 35 to 40 days, they mature as a baby sorrel.

Inflorescence of rounded flowers on a dense, narrow raceme 5-15 cm long. The perianth is reddish or greenish and 4 segmented, 1.5 to 2.5 mm long. Also, the flower contains r stamens 6 and 4 sepals.

Habitat

Mountain sorrel generally grows on wet rocky outcrops, slopes and escarpments, streams, and snowfields throughout the arctic and alpine. They are common throughout native America, except rare in the Queen Charlotte Islands.
