It’s orchid time again

With 30 species of wild orchids found in the Arrowhead Region of Minnesota, along with the breeding bird checklists that get pulled from a file electronic or otherwise, orchid enthusiasts are reviewing their orchid list. From the early spring appearance of fairy slippers, one after another species comes into bloom. A number of other orchids will be blooming soon including the ever popular variety of lady’s slipper species that look like small moccasins.

Some types of orchids are small and obscure while others stand on trail edges, road sides or lakeshores. Many species are associated with wetland bogs and fens and develop in progression at their individual flower times during the summer.
Even more exciting than finding a species that a person hasn’t encountered previously can be finding an individual, rose pogonia or fairy slipper or lesser purple fringed orchid that lack its normal color. Although
some species are less common than others, white blooms of any species are even rarer. Fortunately, the photographer for this article spends a lot of time at orchid locations and has accumulated a growing
photo assortment of white forms of some species. Flowers that are entirely white are referred to as the “alba form” in reference to the lack of typical
flower color. Browsing on line will bring up examples of many photos of species that photographers and scientists have found exhibiting the alba form. Discovery of an individual or a clump of plants with alba blooms raises the excitement level a notch above the already exciting experience of typical orchid colors.
Some studies of the chemical makeup that produces a scent to attract pollinators is much the same in atypical alba flowers. And also some theories suggest that although the alba flowers do not appear to stand out in a way that attracts more pollinators or creates greater seed production, there is some evidence that the typical flowers nearby may benefit by a higher pollination rate and seed production.
One month has passed in the six months of annual orchid time. Biting insects or not, this is the time of year to be out and active and usually well-equipped with a camera or sketch pad or notebook. Many members will be posting photos to the Ely Field Naturalists websites and various social media. The possibilities are exciting to consider including finding a rare alba.
