Arctic vegetation is largely controlled by the mean temperature in July, the warmest month. Arctic vegetation occurs in the tundra climate, where trees cannot grow.Tundra climate has two boundaries: the snow line, where permanent year-round snow and ice are on the ground, and the tree line, where the climate becomes warm enough for trees to grow.

By converting pollen data into plant functional type (PFT) assemblages and interpolating the data, researchers have been able to reconstruct postglacial vegetation patterns around the world. [17] Core sampling and analysis of lake sediments that contain pollen and other plant remains are often used to obtain good records of past pollination cycles.
Alpine plants are plants that grow in an alpine climate, which occurs at high elevation and above the tree line. There are many different plant species and taxa that grow as a plant community in these alpine tundra. [1] These include perennial grasses, sedges, forbs, cushion plants, mosses, and lichens. [2]
When complete, the list below will include all food plants native to the Americas (genera marked with a dagger † are endemic), regardless of when or where they were first used as a food source. For a list of food plants and other crops which were only introduced to Old World cultures as a result of the Columbian Exchange touched off by the ...
The Tundra of North America is a Level I ecoregion of North America designated by the Commission for Environmental Cooperation (CEC) in its North American Environmental Atlas. One of the planet's most recent biomes , a result of the last ice age only 10,000 years ago, the tundra contains unique flora and fauna formed during the last glaciation ...
These herbaceous perennial plants are chiefly native to the mountainous parts of the Northern Hemisphere in North America, Europe, and Asia, [4] growing in the moisture-retentive but well-draining soils of mountain meadows. Most Aconitum species are extremely poisonous and must be handled very carefully.
The WGSRPD defines Northern America differently from the usual geographical definition of North America. Central America and the Caribbean are treated as part of the botanical continent of Southern America; see Flora of Central America and Flora of the Caribbean. The flora of Hawaii is included in Flora of the Pacific.
Lonicera caerulea, also known by its common names blue honeysuckle, [2] sweetberry honeysuckle, [3] fly honeysuckle [3] (blue fly honeysuckle [4]), blue-berried honeysuckle, [2] [5] or the honeyberry, [2] [3] is a non-climbing honeysuckle native throughout the cool temperate Northern Hemisphere regions of North America, Europe, and Asia.
