Up to 5 feet tall, with very few stem leaves (which are lanceolate).

A very airy plant with narrow stems and stalks and with the flowers all well separated from each other.

All the flowers tend to point upwards ± 20°.

The flowers have distinctive long and very narrow sepal tubes, with the yellow petals splaying out at right-angles.

Flowers have five well-separated yellow ray-florets (or 'petals') that are distinctively narrow at the sepal end, and seemingly cut across with pinking shears at just beyond their widest point, giving each one five small points, each one being a flower.

Belonging to the Asteraceae Family (Daisy) there are no central disc florets, and only five anthers, which are splayed out from the centre.

Thus, it probably has the least number of florets of any Daisy family member, fewer that Yarrow or Sneezewort.

The sepal tube is very narrow with ridges, below which are a few very short and triangular sepals. True to form, the whole plant tends to purple.

The lower leaves are very angular and pinnately lobed, the end lobe being large and triangular.

And very different from those of Nipplewort.

Just like many of the dandelion family, the flowers become a seed 'clock'.


Some similarities to : Nipplewort, but whereas Nipplewort has ten or more straggly pale-yellow ray-florets (or 'petals'), Wall Lettuce has only five, the fewest for and member of the Daisy Family, and they are well spaced out.

Moreover, it has only five disc florets as well! Whilst not in the same Genus as the Lettuces (Lactuca), being instead in the Mycelis genus, it nevertheless exudes a similar milky latex if the stems are cut or broken. The upper part is well branched with many well-spaced flowers on the ends of the stalks, all well separated from one another. It is a very airy and thin plant.

Distinguishing Feature : An open structure to the plant with well spaced out branches making photography difficult. The flowers are smaller than most and are pale yellow and has only five petals. Found mainly on walls.

Related to: Nipplewort

Not to ce confused with: Wall Cotonesater, Wall Speedwell, Wall Whitlowgrass, Perennial Wall-Rocket, Annual Wall-Rocket, Wall Bedstraw, Wall Germander Pellitory-of-the-Wall or Wall-rue [plants of similar names].

Habitat includes walls, shady banks, rocks, woodland peripheries, and is often found on lime.
