Buttercup (Ranunculus)

September 1, 2010 Leave a comment Go to comments

This is a flower that you know is there, but you don’t walk past someone’s graden and say ” aww look at that buttercup “. So here is a closeup of one and some details about a flower that you see almost everyday.

They are mostly herbaceous perennials with bright yellow or white flowers (if white, still with a yellow centre); some are annuals or biennials. A few species have orange or red flowers. There are usually five petals, but sometimes six, numerous, or none, as in R. auricomus. The petals are often highly lustrous, especially in yellow species. Buttercups usually flower in April or May but flowers may be found throughout the summer especially where the plants are growing as opportunistic colonisers, as in the case of garden weeds.

The name Ranunculus is Late Latin for “little frog,” from rana “frog” and a diminutive ending. This probably refers to many species being found near water, like frogs. When Ranunculus plants are handled, naturally occurring ranunculin is broken down to form protoanemonin, which is known to cause contact dermatitis in humans and care should therefore be exercised in excessive handling of the plants. The toxins are degraded by drying, so hay containing dried buttercups is safe.

    Mmmmm, nice picture. I found you through Bob’s GlasgowEye blog . . . what lens are you shooting with here? I just got a DSLR in late February of this year and am extremely conscious of how far I have yet to go . . .

      Hi Jenna

      This shot was taken using a Canon EF-S 17-85mm 4-5.6f IS USM lens.
      If you zoom your lens as far as it can go then physically move backwards and forwards until your auto-focus kicks in, that will be the most you can get from the macro end of your lens.
      After I took this shot, I then cropped it to the composition that I was looking for.

      Hope this was helpful for you.
      Mark.
