A Garden Like no Other
The warmer Gulf waters provide the city of Tromsø and its environs with relatively mild winters, the average winter high hovering around 40 degrees Fahrenheit. Snow generally accumulates from October to April and usually has melted by mid-May. Summers are cool, with average highs in the mid-50s.
Daylight is another important weather factor for gardens this far north. From mid-May until the end of July, the sun never sets completely. Theoretically, the potential average hours of sunshine during this period is 680. That number is mitigated by cloudy weather, so the actual average is about 200 hours. However, even when it's cloudy, there is still daylight, which has a positive impact on plants. Not only do they grow more rapidly than their counterparts further south, but their blossoms tend to be larger and, thanks to the cool temperatures, the colors are much brighter.
The Garden opened in 1994 and is located on the grounds of an old farmstead that covers about four acres. In 1947 the last owner of the farm willed it to Troms County, in which Tromsø is located. Today this acreage houses the Garden, the Tromsø Museum, and most of the University of Tromsø. The Garden is open to the public from late May to early October. There is no entrance fee.
Arctic and alpine plants from all over the Northern and Southern Hemispheres inhabit the Garden, but many other species more familiar to gardeners in temperate regions of the world have found a happy home here as well. Among them are buttercups, campanulas, columbines, crocuses, various herbs, ligularias, lilies, pinks, primulas, and rhododendrons.
The thousands of species and cultivars that the Garden displays are arranged by geographic area and grouped by botanical association. Helping to divide and separate the various plant collections are gravel paths, rocky outcroppings, and other natural elements of the terrain. A unique feature, not found in other botanical gardens, marries botany with geology. All types of naturally occurring rock are identified with markers. Even the Garden entrance is surrounded by labeled rock specimens and interpretive signs.
While it's not possible to take you on a real live tour of the garden--and even then it would be covered by a blanket of snow at this time of year--I'll do the next best thing and give you a brief photo tour. On your right is a series of photos from the various garden areas. Below is some more information about Tromsø and links to information about plants named in this article.
