Growing in a moist place a mile south of Southport which may occasionally get washed by a high tide.

There are small groupings of pale-lilac flowers atop a very thin un-straight stalk.

Widely separated singly-pinnate leaves appear alternately on the stem. The leaflets are like fine feathers: very short and even more narrow, a little like those of Yarrow. The dark-green leaflets may be reddened to a dark purple sepia tone.

The flowers have four lilac-coloured petals, with a yellow centre. The seed pods which grow beneath the flowers are on long stalls and very narrow and cylindrical.

The 5 sepal cups supporting each flower. As the stem grows so too does the distance between the flower stalks.

The flowers are on very long, somewhat droopy stalks, now fairly well separated from each other. The sepal cups turn yellower.

Bird's-eye view of a young plant. The sepals, greenish at first, turn yellow with reddish marks at the rounded tips.

The four petals are round and overlap each other in the centre. Stamens, which are grooved and recurved, number six; anthers are discoidal and yellowish green.

Petals have deeper-lilac veins. The central 'disc' will become the cylindrical seed pod.

Fine long-oval leaflets are long and narrow, with but a few only to each singly-pinnate leaf and in singles on alternately opposite sides of the stem. From afar it looks as though the fine leaflets are on a circular stalk, but it is actually a flat stalk curled up tightly to form a slit cylinder. Leaflets reddish-brown at tips. Basal leaves (not shown) have rounded leaflets on single-pinnate leaves.

The curled-up nature of the leaf rachis can also be seen in the lower leaf here.

The very lowest leaves are a different shape, being almost circular with one at the tip and 3 (or more) other almost circular ones in opposite pairs (best seen in those near the bottom in the centre and just to the right).

The leaves and stems can sometimes turn a reddish-brown, to protect themselves from excess sun and heat.

Double-flowered form.


Hybridizes with: Wavy Bitter-cress to produce Cardamine × fringsii, which occupies fewer than a dozen isolated tetrads in the southern half of England only.

Some similarities to : Greater Cuckooflower (but that has pinnate stem leaves with rounded rather than narrow leaflets), Coralroot (which has toothed stem leaves which are single rather than pinnate), Pinnate Coralroot (which grows in but four well isolated hectads).

Not un-like: Water Violet (but that has five petals and grows in shallow water) and to Dame's-Violet which is much taller.

Uniquely identifiable characteristics: Grows near water unlike Honesty which looks a little like it, but Honesty is much taller with purple (or white) flowers and large leaves.

Distinguishing Feature : The fine pinnate leaves roughly half-way down the otherwise bare stem.

No relation to : Lords-and-Ladies nor to Lady's-Mantle, Lady's-Slipper Orchid, Autumn Lady's-Tresses, Irish Lady's-Tresses, Lady's Bedstraw, Lady's Teardrops nor Lady Orchid, [plants with similar names]
