Bee Magnet

There is one shrub in the garden that is always covered in bees at this time of year.  There are so many attracted to it that the sound is akin to a distant swarm.  I think the shrub is a variety of Euonymus but I have never been absolutely sure about that.  The flowers scarcely open beyond the tightly furled bud but the bees can clearly get to the nectar inside and positively love it.
