The nature of Taimyr peninsular is rather severe. In summer after sunset temperature falls to 3C (37.4F). And even in such conditions the vegetation of Taimyr is rich enough. Plants have to survive in a cold polar summer and leave offspring in thawed soil over the permafrost.
The climate is closely connected with permafrost: when the sun doesn't shine, the air is getting cold fast.
Moss, berries and flowers grow everywhere.
This is cloudberry hiding among the leaves.
And this is blueberry.
