The month started very warm and sunny and the western end of Brambly Hedge started to burgeon. The area is roughly a 1 metre cube and is another good example of a very small nature reserve looking rather like a green igloo with various leaves and flowers poking out of the tope. Brambles provide the basic structure and support and some of the other plants that flourish in the sheltered area are tufted vetch, narrow-leaved vetch, goosegrass, black bryony and red campion.
The weather was now turning quite hot and grasses such as rough meadow grass, Poa trivialis, are in anthesis (flowering). The white powdery oak mildew, Erysiphe alphitoides, has started to appear on oak leaves, as it always does at this time of year, and later in the month I spotted that remarkable gall known as a bedeguar or robin's pincushion on what I think is a field rose, Rosa arvensis, growing in the penumbra of M3. The galls are made by a small wasp, Diplolepis rosae, but this is usually outnumbered by inquilines who get a free ride in a gall they haven't made.
