There are many serious concerns for the health and numbers of bee and butterfly populations, both in the UK and worldwide at the moment - so I am always delighted to see even one or two bees in my garden. At the moment, though the day is overcast after some quite heavy rain, I am very happy to tell you that the garden is just humming with little black and yellow honeymakers.
I do plant particularly with bees and butterflies in mind...the Oregano flowers above are one of their favourites - but the super-magnet this summer is the Veronica. It's a somewhat nondescript herbaceous perennial for most of the year - but for about six weeks, its blue spikes have both looked elegant and attracted the most enormous numbers of bees.
A photograph cannot do it justice - but here you can see that each spike has not one but (at least) two happy bees crawling all over it and returning time and time again to sup up what it has to offer.
If you can only do one thing for wildlife in your garden - plant something bee or butterfly friendly. There are many suggestions here (in a downloadable list format) and you will be doing both the planet and yourself a favour - watching these creatures becomes entrancing - and - in the case of the herb garden, you as well as the bees and butterflies can enjoy the produce of the plant. That's what I call a 'win-win' situation!
