Alaska Adventures: Alaska’s Botanical Gardens

Posted by csjones

Botanical Gardens are very popular to people who travel, so they can see what types of plants and trees that thrive in the worlds different climates. Many people who visit Alaska are astonished that they have a botanical garden, because they assume it is too cold to have plants grown and thrive in Alaska’s harsh atmosphere, but the average annual precipitation in the Anchorage area is just over 15 inches. The average annual temperature is only 35.7 degrees Fahrenheit. In June, July, and August, the average daily high temperatures are in the mid 60’s, with a range from 55 to 80 degrees.

With the longest day of the year usually falling on the summer solstice, June 20 or 21, means lots of sunlight for plants to grow. In Anchorage, the solstice brings 19 hours and 20 minutes of daylight. Anchorage’s shortest day of the year is in late December, with only 5 hours and 28 minutes of daylight.

In the Anchorage area, the growing season is about 120 days long. The first frost-free date can vary widely, from the end of April until the end of May; and the first autumn frost may occur anytime between the end of August and the middle of September. A “typical” growing season is mid-May through mid-September. Changes in elevation of 500 feet in the Anchorage bowl can shorten the growing season by one week on each end.

Ah, but thrive they do and so visiting Alaska’s Botanical Gardens in Anchorage is a must to see to gaze upon all the different species of plants that grown in their climate.
