Busy Bee

Caught this lovely Bee on a Comfrey Plant, 
Comfrey are important herbs in organic gardening and are used as a fertilizer and as an herbal medicine.
We acquired some years and years ago for making compost, and now they rule the garden. We will never be free of them unless we use a really strong weed killer which we wont, so we just have to dig them up every year, but if you leave a tiny bit in and it's up again in next to no time
