Winter-cresses



This week, I have seen several examples of Winter-cress growing locally in Newtonmore. It is not common around here but is very easy to spot when it is flowering as it has bright yellow flowers, with four petals arranged in a cross (it’s a crucifer).
Winter-cress (Barbarea vulgaris) is growing up Glen Banchor in the quarry/car parking space just past the second cattle grid. I only noticed it last year but there is a big clump which is unmissable as it is the only plant growing in the sandy bank.

It is there again this year and a few more plants have seeded around it.

  Another place it is growing is the corner where Station Road meets the track to the Jack Richmond Park.

It has shiny green leaves. The upper ones on the stem are fairly simple with a few lobes.

The second sort is Medium-flowered Winter-cress (Barbarea intermedia) which is on the Wildcat Trail which goes alongside the Kingussie Road (B970).  This one is generally smaller than Winter-cress.

One way of telling them apart is by looking at the leaves up the stem, their shape and how they clasp the stem. Medium-flowered Wintercress has leaves up the stem which are more deeply cut into lobes and where it meets the stem there are two projections sticking out past the stem.  
Medium-flowered Winter-cress auricles
 In Winter-cress these “ears” (botanical term is auricles) are not as long and don’t stick out past the stem, and the leaves are less deeply cut.

I also have a third variety   in the garden called American Winter-cress (Barbarea verna). It is like a very large version of Medium-flowered Winter-cress.

The stem leaves have the same kind of  sticky-out auricles as Medium-flowered Wintercress.

 The seed was sold as an alternative to water-cress which will grow in drier conditions.  I won’t need to buy it again as it self seeds around the garden. It is not as productive of foliage as water cress would be and has a peppery taste.
