English: Blue flowers along The Beck. The brighter blue star-shaped flower in the foreground is Borago officinalis, Borage or Starflower. Pairs of oval, hairy, crinkled leaves are topped by drooping sprays of star-shaped flowers of an intense, startling blue colour. The whole plant has a bristly appearance. It has a slightly cucumbery taste and flowers can be added to salads and to summer drinks. Borage is extremely attractive to bees. The softer blue flower is Phacelia tanacetifolia, also known as Scorpion Weed. The Phacelia family comes from the Americas, with most species originating in California. This has become widely naturalised on European roadsides. The leaves are finely cut, almost fern-like and the lavender-coloured flowers are extremely attractive to bees, as it is a good source of both nectar and pollen. It has a use as a green manure and has also been planted in field margins to attract hoverflies which then act as a biological control of pest species affecting crops.
