Rosemary ant

The rosemary flowers have started to come out in the past few days. The bees are only showing moderate interest in the flowers at this stage, presumably because they're quite small and have a tiny amount of nectar inside; and also because there are richer pickings available nearby.
For example, the large cluster of thriving sweet basil bushes are only a couple of metres away, and while the flowers are a similar size to the rosemary's, each stem is covered by dozens of tightly packed flowers, and each bush has scores  - if not hundreds - of stems. So as far as the bees are concerned, the basil offers a full-scale nectar feast compared to the rosemary's modest but tasty snack.
But of course for the humans amongst the garden wildlife, rosemary's main attraction is the wonderfully spicy fragrance from its evergreen needle-shaped leaves, and the taste rush produced when its leaves are used in a variety of dishes. For example, there's something almost magical about dishes featuring a combination of rosemary and lamb; or rosemary and potato. Hard to beat.
Salvia rosmarinus plants produce flowers in pink, purple, white and blue; and is a member of the mint family Lamiaceae, which includes many other herbs - such as oregano, basil, sage, marjoram and lavender - used in a wide range of medicinal and culinary applications. 
So a pretty useful plant here, and nicely aromatic, and tasty, and looks good to boot - especially in a hedge formation, and especially when flowering.
