Ground Ivy

Just one of the many tiny delights provided by springtime flowers.  This is Ground Ivy.  It's not related to ivy but it does retain its leaves through the winter.  In sunny places the leaves turn purplish. 

The plant was also known as Gill and was used to flavour beer before hops were introduced to England in the 16th century.  As well as gill-beer, gill-tea was also used as a cough cure.
