Thyme-leaved Milkwort (Polygala serpyllifolia)










































The dryer areas of the Dorset heaths are not well known for the array of flowers to be seen, heathers are the dominant species and there is little scope for much else.

However, between May and September this tiny little flower, the thyme-leaved milkwort holds its own, especially along footpaths and areas where the heather is less well established.

Going purely by appearance, telling this from common milkwort and chalk milkwort is very difficult. However, I know this flower better as heath milkwort as it loves acid soils and is commonly found on heaths whereas the other two prefer chalk, and so that narrows the choice down somewhat.

The thyme-leaved or heath milkwort is also a deeper blue, not so bright as its cousins.
