Speaking of Comfrey [see last entry] there is a good harvest of it on the allotment which I put in a bucket to steep in water. Comfrey "tea" is said to be rich in nutrients which are released as the leaves break down. 

 This Comfrey is Symphytum officinale or perhaps Symphytum x uplandicum which is a cross between S. officinale and S. asperum.  I can't really tell the difference and Comfreys hybridize readily. The flowers are pinkish-purplish and appear in early summer.
