Übersicht
Greenland stitchwort2 is a beautiful3 rare perennial4 which grows low to the ground in clumps linked together at the bottom4. It has three to five pairs of leaves in a linear opposite pattern along the length of the slender stem3. The main stem breaks into one to thirty cymes which each flower separately3. The flowers are white and exist five to ten centimeters off the thick foliage4. The white flower pedals are six to ten millimeters long4. There are five green sepals on each cymes5.
Reproduction
The plant has a peak flowering time of two weeks in the middle ofJuly5, although it does flower frequently anywhere between June to August6.
In this period pollen grains are transported from flower to flower by insects5. The most effective insect to transport pollen grains is the bumblebee (Bombus terricola)5. This is due to tiny hairs on the bee that collect pollen5, and the bee crawls over the flower in lower temperatures when it is unable to fly5.
Habitat
Greenland stitchwort is found in areas of high elevation where bedrock is exposed5. The plant grows on rocky ledges and in fine gravel on slopes4. The soil has been noted to have a pH of 3.1 to 4, and is low in nitrogen and phosphorus, but containing a high organic matter content5. The climate in these areas receive frequent fog and cloud cover with considerable precipitation5. One study area for this plant recorded an annual precipitation average at 1837.5 millimeters5, along with wind speeds averaging at 50km/h5. The mean annual temperature at this location on Mount Washington, NH was -3.0°C5. These conditions have a large influence on plant and animal life5.
Economic Value
Minuartia groenlandica was studied for use on roof tops for insulation and urban greening as an economic use, but was unable to sustain drought for long enough7.
Distribution
The plant exists in many isolated and elevated areas, such as large mountain plateaus4. It's residing includes NU, ON, PQ, NL, and NS for Canada8. And in the US it is found in ME, NH, VT, NY, WV,VA, TN, NC, and SC8. It also be found in Greenland, Denmark5. Within Nova Scotia this plant is found in Inverness County and along the south shore in only a few areas6.
Conservation
In Nova Scotia Greenland stitchwort is sensitive to interference by humans and natural events9. The conservation status in Nova Scotia is yellow9.
