Has leaves only at the base of the plant. There are usually between 2 to 7 flowers (sometimes up to 28) on flower stalks between 15mm to 60mm long.

The stem is 30 to 50cm (max 60cm) long and a pale yellowish-green, sometimes purple-flushed as here on the right. The stem hairs are a mixture of simple non-glandukar hairs with sometimes with short, dark glandular hairs. Sometimes there are a few stellete (branched) hairs in the upper part of the stem.

The flowerhead is rounded at the base. The bracts are linear-lanceolate, 8 to 12mm long and 1.0 to 1.5mm wide, greenish-black, the inner bracts having paler margins. They have a long taper ending either ending abruptly or with a point at the end. The bracts have either short or long, pale non-glandular hairs which have a dark 'root' mixed in with short, dark glandular hairs. The hairs on the margins of the bracts are numerous and stellate (have a few 'umblella spokes' at the top).

Leaves frayed at the edges? I'm afraid so.
The leaves are a bit floppy (if it were not for all the extra gubbins in this small space), glaucous-green on the upper surface, glaucous paler underneath (although it is hard to tell which are the upper and lower surfaces here...). The leaves are sometimes suffused with a purple tint and sometimes spotted. Leaf shape is elliptical or nearly round. At the apex they are either rounded or bluntly acute. The edges dense with simple non-glandular curly hairs.


Easily mistaken for : many other of the >450 Hawkweeds (Hieracium species)

It is a native Apomictic plant which inhabits rocks, quarries, cliff ledges, rubble and even grassy banks. It is the most abundant Hawkweed in the Derbyshire and Staffordshire limestone dales in early summer! Also found on the Great Orme, North Wales.

Not to be semantically confused with: Confused Hawkweed (Hieracium britannicoides)
