We Have Pollination!


Day 291: We have pollination! Yes, my milkweed plants are making pods! And I cannot credit the success to my intervention because the flower I attempted to pollinate by hand is not among those with swelling ovaries. That said, there are at least a dozen strikingly obvious developing pods on the plants which flowered earliest, and I think there will also be some on the plants which came into bloom a little later. It's too soon to tell with those, although it looks like a few of the flower stems are beginning to curl (as opposed to drooping). That was what caught my eye first: one curled, plump flower stem held above a mass of withering flowers. Closer examination revealed an ovary starting to swell, and then as I raised my eyes, I saw this pod, about as big as the end of my thumb! Then I really started peering in among the fading flower clusters, and saw that the pollinators had done the job I'd failed to do. Finally, I'm going to have milkweed pods!

Bee Hopeful


Day 281: I have good reason to "bee hopeful" that my milkweed plants will produce seed pods this year. They are absolutely covered with a large assortment of insects...stinging insects, mind you!...who visit one flower after another. Bees dominate the mix, but there are wasps of every size from miniscule to man-eating, so I stood well back and zoomed in for the photo. Can I identify them? No, although I think I can safely say that these two are honeybees, a species to which I am deadly allergic. Was I worried that I would get stung? Not at all, because they were firmly focused on the work at hand, gathering nectar from the sweet-scented flowers. Surely sombody's going to get pollinia caught on a leg!

My Very Own Asarum


Day 209: The internet. I refer to it as "the world's largest source of misinformation." Let's use Mr. Vogel and Asarum caudatum as our example. In 1978, Vogel published a paper stating that his "observations covering a period of several years have shown that Asarum caudatum is regularly pollinated by fungus gnats." A few short years later, this was roundly debunked by another botanist, K. Lu, and it might have ended there but for the subsequent development of personal computers and the true villain, the world-wide web. Scores of other scientists have provided abundant evidence that Vogel was talking through his hat, but excerpts from his paper began cropping up on the 'net as soon as it was birthed and spread quite rapidly as harmful invasive species are wont to do. Vogel's kudzu of erroneous information propagated at a phenomenal rate, crowding out the native truths. Sound familiar? I promise you, this is not a political post. We now have a wealth of research to support the hypothesis that Wild Ginger (Asarum caudatum) is autogamous/allogamous (self-pollinating/cross-pollinating), and that while coincidentally, fungus gnats may lay their eggs in the blossoms, they do not play a significant role in the plant's reproductive processes. And them's the facts. (And thank you, Arnie, for a wealth of reading matter on the subject.)
