One great thing about yucky, cold February Days is staying inside where it is warm and planning the spring planting of your flowerbeds. This year we know the Monarch Butterflies are in steep decline along with the honeybees and other pollinators including the hummingbirds. Every human on Earth needs to take responsibility for increasing the beneficial pollinators around the globe. We can stop the use of herbicides and pesticides that are killing the pollinators. Most of all, we can grow more flowers everywhere! Use your cold days to do some planning for flowers to promote the growth of insects and birds. I have shared an excerpt from Wikipedia on pollination. For your photostudy, I went back to September of last year and pulled out some of the hummingbirds. Enjoy!

There is a new movement to get farmers to grow wildflowers in with crops to attract more beneficial pollinators. Read more about this at the following link:
- Cross-pollination, also called allogamy, occurs only when pollen is delivered to a flower from a different plant. Plants adapted to outcross or cross-pollinate often have taller stamens than carpels or use other mechanisms to better ensure the spread of pollen to other plants' flowers.
- Self-pollination occurs when pollen from one flower pollinates the same flower or other flowers of the same individual. It is thought to have evolved under conditions when pollinators were not reliable vectors for pollen transport, and is most often seen in short-lived annual species and plants that colonize new locations. Self-pollination may includeautogamy, where pollen moves to the female part of the same flower; orgeitonogamy, when pollen is transferred to another flower on the same plant. Plants adapted to self-fertilize often have similar stamen and carpel lengths. Plants that can pollinate themselves and produce viable offspring are called self-fertile. Plants that cannot fertilize themselves are called self-sterile, a condition which mandates cross pollination for the production of offspring.
- Cleistogamy: is self-pollination that occurs before the flower opens. The pollen is released from the anther within the flower or the pollen on the anther grows a tube down the style to the ovules. It is a type of sexual breeding, in contrast to asexual systems such as apomixis. Some cleistogamous flowers never open, in contrast to chasmogamous flowers that open and are then pollinated. Cleistogamous flowers by necessity are self-compatible or self-fertile plants. Many plants are self-incompatible, and these two conditions are end points on a continuum.
