Species of the Month - July 2014

Melancholy Thistle

Cirisum heterophyllum


The name does not mean the plant itself is melancholy, but that it supposedly cures melancholy in humans.  Culpeper claimed it "makes a man as merry as a cricket".  Modern herbalists don't seem to use it, but the sight of its flowers on a hillside is still very cheering.

Melancholy Thistle is easily told from other thistles as it is not a prickly plant.  The stem completely lacks spines, and the leaves are edged with soft spines that you can easily crush in your hand without pain.  The underside of the leaves is covered with a dense white felt.

The plant is widespread but not common.  It occurs on road verges, heathery moorland and damp grassland, sometimes in large patches.  It can occasionally be found in woods, where it often doesn't flower but can be recognised by the distinctive leaves.

The basal leaves are long-stalked and can be very large.  The upper stem leaves are stalkless and surround the stem with large basal lobes (auricles).

Melancholy Thistle grows to about 1 metre tall and the flowers are about 5-6 cm across.  The only similar British plant is Meadow Thistle, which is not known from our area though it occurs in Kintyre and Islay.  It has flowers only half the size of Melancholy Thistle and grows in wet peat.
