Less than a foot high, when mature it is an open plant arising from a single stem which birfurcates a few times. Flowers in clusters atop each stem. Few leaves, in opposite pairs, just below the bifurcations.

From above, the cluster of flowers is surrounded by several leaves/bracts of various lengths, appearing asymmetric.

Flowers have five petals of slightly un-even length, the longest preferring to be on the outside of the umbel and which may be arranged in a circle. Thus, although not a true Umbellifer (Apiaceae), the flowers do have some similarities. The leaves/bracts have short hairs on the edge.

The tiny flowers are off-white, tinged lilac or azure to blue. The lilac tinges of the white flowers have the appearance of one of those colour optical illusions based on after-images, neural adaption and opposite colours.

An umbel of flowers, with several flowers in each green-bracted cup, and several cups within a few larger leaves/bracts.

The cups containing several flowers each are held above longer bracts/leaves.

Un-like Common Cornsalad which has rounded lower stems, Keel Fruited Cornsalad has lower stems that are square. Note the ridges with short hairs on each edge.

Basal leaves but two in number, followed quickly by an opposite pair of stem leaves.


Some similarities to : Common Cornsalad and other Cornsalads. Its location on the Sefton Coast precludes it being any of the other less-ubiquitous cornsalads such as Broad-fruited Cornsalad, Hairy-fruited Cornsalad or Narrow-fruited Cornsalad.

No relation to : Corn Buttercup, Corn Marigold, Corn Chamomile, Corn-cockle, Corn Mint or Salad Burnet [plants with similar names].

Inhabits bare or sparsely grassy earth, rocks, walls and sand dunes, where the above photographs were taken. The flowers are extremely small, less than 2mm across, and appear white but with either blue, azure or lilac patches. It belongs to the Valerian Family, but is not in the same Genus as either Red Valerian nor that of Common Valerian, which are both in differing Genera.
