This creates a dry environment, despite the fact that precipitation regularly falls out of the sky in huge amounts. Southern alpines from longer growing seasons can have the luxury of blooming later in the season, but those from the high or northern alpine regions have to bloom and set seed within a few short weeks. On a sunny day, even when the air temperature is slightly below freezing, the temperature within a mounding alpine can be several degrees above freezing, allowing the plants to commence growth. Plants have also had to evolve a set of vegetative and regenerative adaptations to survive here on the physiological border of the Earth’s biosphere. Since most of the plants require water, humidity, sunlight, fertile soil and other conditions for optimal growth, it’s really interesting to know that plants found in the tundra … Most alpine plants are adapted to grow in sandy and rocky soil. Outdoors I grow mostly alpines, bulbs and ericaceous shrubs. Wind is an ever-present problem in arctic-alpine environments. This can lead to above freezing temperatures around the plant even when the air temperature is below freezing. This feature allows them to start photosynthesizing as soon as the air temperatures rise above freezing. Tundra Plants Are Dark in Color Dark colors absorb and retain heat better than light colors. Plant Adaptations.
