The Labrador tea shrub is a heath with aromatic leaves that will grow up to six feet tall in regions south of the tundra. Heaths are found in the low arctic tundra and the smallest, hardiest dwarf heaths are found in the mid-arctic tundra. No heaths can withstand the conditions of the northern-most high tundra. And the Salix Arctica, the Arctic willow, is a tiny creeping willow. It is adapted to survive in Arctic conditions, specifically tundra's. Eriophorum (cottongrass, cotton-grass or cottonsedge) is a genus of flowering plants in the family Cyperaceae, the sedge family. They are found throughout the arctic, subarctic, and temperate portions of the Northern Hemisphere in acid bog habitats, being particularly abundant in Arctic tundra regions.
Temperate means mild, moderate. If you're a temperate person, you are calm, reasonable. If you live in a temperate climate, it's warm and sunny, but not too hot.
<span>An eon is a geologically around tens of millions of years. A period is a million year included in an eon which is also made up of several eras. Therefore my answer is a period due to it being a subset of an era which is a subset of an eon.</span>
