365Caws is now in its 14th year of publication, and was originally intended to end after 365 days. It has sometimes been difficult for me to find new material, particularly during the winter months, but now as I enter my own twilight years, I cannot guarantee that I will be able to provide daily posts. It is my hope that along the way I may have inspired someone to a greater curiosity about the natural world. If so, I can rest, content in the knowledge that my work here has been done.

Second Experiment
Day 297: Despite the fact that Akebia fruits (Akebi) have absolutely nothing to recommend them as edibles, my success at hand-pollinating them last year led me to wonder if I could repeat the experiment with similar results. Testing should never be a one-off. If results are not reproducible, you can't claim success. To that end, when the Akebis bloomed this spring, I got out my trusty camel-hair brush and started checking flowers daily for pollen production and receptivity. Once again, very few female blossoms appeared on the white-flowered vine as compared to the purple variety, and conversely, none of the male flowers on the purple Akebia matured to the pollen-making stage. Consequently, I was only able to transfer pollen from white male flowers to purple females; nevertheless, I got results, and seven Akebia fruits are coming into their maturity. I now know that I waited too late to pick them last year and that the seed/pulp ratio was skewed to the "seed" side of the equation. As for their potential as edibles...well, as a good scientist, I'm going to have to see this experiment through to its conclusion, although I don't expect the final stage to vary from previously recorded data. In other words, "Ugh!"
