Meadow-rues are wind pollinated. Seems like it might be a chancy and inefficient process where these grow deep in the woods. Other species are taller, and grow more in the open - more out in the wind. But clearly it works. One technique that helps is that the pollen producing plants are taller than the pistillate ones at the time it's all happening. Did I succeed in making this look like anemophily is in progress in this shot?
