Autumn Rose

Autumn 2015 has been particularly great for roses here in Cambridge. My garden was full of roses in their second blooming flush this year and some are still in bloom (in November). This particular english rose has heavy blooms that almost bend the thin branches to the ground.

This photograph has a natural black background generated by the use of a off-camera slave flash at right angles combined with a small aperture f/11 and exposure time of 1/250. Click on the photo for options to view this in larger size on Flickr.

Vibrant Rose!

There is this rose bush in my garden which struggles to survive every year regardless of what I try to do make it feel happy. But year on year it produces one or two of these really vibrant flowers in autumn! Just one of two roses sadly before the winter frosts kick in.

The Food Chain..

One thing they teach in school biology is the concept of food chains and food webs – the links that show interdependence of organisms based on the foods they eat. The photo below shows one such food chain starting with the rose (the producer) providing nourishment in the form of sap for aphids. In turn aphids are milked by ants for honeydew, a secretion that aphids produce.  Ants are also known to “farm” aphids storing their eggs over winter and then carrying newly hatched aphids to emerging plant shoots in spring (called a mutualistic relationship).

A mini food chain. In this picture clusters of aphids can be seen underneath petals of the rose, and ants that farm these aphids. Click on the photo for a larger version on Flickr.
