By dropping these model seeds and filming their descent with high-speed cameras, they demonstrated that whirling, single-winged seeds were the most effective at aerial dispersal. Sometimes seeds have thin wings as an extension of the seed that enable them to glide in the wind. I’v noticed over the years of observation that the best type of results of dormant seeds blooming are by accident or grounds development. Mostly by wind.
