Description
A Single Buttercup (genus Ranunculus) and two Stinky Bob (Geranium robertianum) blossoms, photographed on the Butler Creek Trail south of Binford Lake, Gresham, Oregon. The buttercup is a nice summery flower and its color contrasts to the purple blossoms of the Stinky Bob, which is an invasive species of weed. See my other Buttercup and Stinky Bob shot. In this horizontal composition, the yellow blossom of the buttercup is central and is framed on either side by the contrasting colors of the purple Stinky Bob flowers. The buttercup is also well in focus, while the Stinky Bob blossoms are relegated to the background and are somewhat out of focus (like the rest of the background), contrasting with the sharp focus of the central subject. The light is even and soft throughout the frame. Flowers are used by plants for sexual reproduction. They contain the plant’s reproductive organs. The female organs are in the pistil, which is often a single center stalk within the blossom. The pistil is made up of the stigma, style, and ovary. The male reproductive organs are in the stamen. Often there are many stamens, each a filament with a bulb (anther) on the end, surrounding the pistil. On the anthers you find the pollen granules, each granule containing the plant’s sperm. The purpose bright colors and scents and nectar of the flower is to attract animals like bees, butterflies, and hummingbirds, so that the pollen can be transferred from the stamen to the pistil, or to the pistils of other flowers (even on other plants of the same species). In this way the ovum are fertilized and the plant’s fruit develops, containing the seeds which are the product of the plant’s sexual reproduction and will develop into adult plants.
