Chalk Milkwort

The Chalk Milkwort, or Polygala calcarea, is a rare native of warm chalk grassland.

Well, this is a treat. Slowly plodding through chalk grassland this afternoon at Sands Bank nature reserve in Buckinghamshire, I came across a jolly scarce plant.

This tiny, tiny, tiny little plant is the Chalk Milkwort, or Polygala calcarea. It is scarce, and grows on chalk grassland in the south of England.

Isn’t it the tiniest, sweetest, bluest plant you’ve ever seen?

Of course, the reserve had many other wild flowers, including this Carline Thistle:

To the uninitiated, Carlina vulgaris looks like a normal thistle that has finished flowering. But oh no. These yellow-brown short petals are as extravagant as this native of dry, warm, chalk grassland gets.

There was common toadflax (Linaria vulgaris):

And Greater Knapweed (Centaurea scabiosa):

I had come looking for the Autumn Gentian and its rarer relative the Chiltern Gentian. But I found none. From a distance, I thought this clustered bellflower might be one:

wild campanula

Of course, it was Campanula glomerata, and a very fine display there was too.

The Sands Bank reserve is lovely – though it does have a rather unprepossessing industrial estate at its feet. While I shall clearly have to travel further afield to find my gentians, I’m chuffed to have found such a tiny rare wild flower in Polygala calcarea.
