Yellow Lady’s Slipper Flowering

5-30-13 yellow lady's slipper 063There are only about three short weeks in the late spring when the blossoms of Yellow Lady’s Slippers grace our woodlands and wetlands. The production of an orchid is a complicated process. If pollination and fertilization are successful, hundreds of thousands of some of the smallest seeds of any flowers are scattered by the wind. The seeds of Yellow Lady’s Slippers (and other orchids), unlike those of most flowering plants, contain no food for the seedling plant. In addition, the coating surrounding the seed is extremely tough, so much so that the seed can’t germinate until Rhizoctonia fungi digest the outer coating, which allows the inner seed to access soil nutrients. This can take two years or more and then it may take another few years for the plant to produce a flower.
