365Caws is now in its 16th year of publication. If I am unable to post daily, I hope readers who love the natural world and fiberarts will seize those days to read the older material. Remember that this has been my journey as well, so you may find errors in my identifications of plants. I have tried to correct them as I discover them. Likewise, I have refined fiberarts techniques and have adjusted recipes, so search by tags to find the most current information. And thank you for following me!

Antennaria Microphylla, Rosy Pussytoes
Day 278: Pussytoes! Or as I say to Tippy when I blow on his feet, "Pussyfoots!" The pink "blossoms" you see here are actually rose-coloured bracts which surround the true flower: yellow, inconspicuous, and capable of a remarkable reproductive feat: Antennaria microphylla can set viable seed without being fertilized. In botany, this phenomenon is called apomixis or agamospermy. The plant is also capable of sexual reproduction, doubling its opportunities to create a new generation of Pussytoes. Individual colonies of Rosy Pussytoes are likely to be genetically identical, i.e., clones of themselves. Having a backup reproductive strategy is more common in flowering plants than one might expect. Other species which can reproduce by means of apomixis include dandelions and hawkweed.
