An early-bird floret amongst many narrow leaves. [Only the school playground is left here (and that too will soon be houses); the school itself has gone, and good riddance too - it was an awful school to have to go to!]

The linear leaves. Often a very-small whorl of leaves (the others shorter than the main one) emerge from one place. Older and woodier parts of the stem have turned browny-red. The stems branch.

The plant is sub-glabrous, meaning that it may be hairless, or it may have very short hairs hardly noticeable apart from on the paler parts of the green stems (top leftish).

Bottom left shows an auricle on the ligules just beneath each linear leaf. Other leaves with auricles also shown.

All seeds with 'parachutes' flown the nest.


Not to be semantically confused with : Perennial Ragweed (Ambrosia psilostachya) or Ragweed (Ambrosia artemisiifolia) but these totally lack any ray florets [more members of the Dandelion & Daisy Family (Asteraceae)]. Nor with Ragged-Robin (Silene flos-cuculi) [a member of the Campion family (Caryophyllacaea)].

Some similarities to : other Ragworts but this one has long narrow leaves.

Uniquely identifiable characteristics

Distinguishing Features : The features which, together, distinguish this from other Ragworts are: Stems are woody towards the base. Leaves linear, narrow usually entire (without teeth) and auriculate (stalkless, with small auricles each side of stem); greyish on underside. Leaves and narrow, mostly entire. Flowers yellow 10-25mm across with 10-15 ray-florets. It is sub-glabrous (almost hairless or with slight downy hair).

A garden-escapee and wool-alien which is being increasingly found growing wild. Spreads by parachuted seeds.
