Plants produce flowers not to look nice for photographers or other people, but to attract insects for pollination. The amount of flowers in the Arctic indicate that there must be insects available that could take care of that pollination. However their numbers are really small, so most plants also have other -asexual- ways to reproduce. The Spider Plant is a very nice example for that. Spider plants produce runners, a horizontal stem, with at the end a tiny new plant. Genetically a copy of the mother plant, but also able to grow for two years. So if the mother plant dies after two years without having produced seed, the clones will survive and will try to do the same.
This Spider Plant I found in Sorgfjord, a place at the north eastern side of the main island of Spitsbergen. It is not very common, but I knew it was growing on this site the last time I was there. As we had some people onboard who were interested in flowers, I decided to have a look if they were still there. And they were, to great joy of most people.
