A white marsh thistle (Cirsium palustre)

The solitary marsh thistle in The Waste, a plant I have been watching since last autumn, came into flower today and, rather surprisingly, it is white.

Emthree and The Waste have had several plants of this biennial species in the past and they have all been the usual red-purple. White-flowered marsh thistles are not uncommon in the wider countryside, but I do not recall seeing them in the garden here.

Purple flowers are particularly attractive to certain insects such as carder bees and it will be interesting to see which species visit this white one.
