The leaves of Tall Fleabane are stalkless and attach broadly directly to the stems but are not supposed to clasp the stem! (as they do here)

The stem leaves of Tall Fleabane are lanceolate to oblanceolate and only sparsely hairy, but are not supposed to clasp the stem! (as they do here). Stems round to ribbed, sometimes square.

A very similar plant, Robin's Plantain (Erigeron philadelphicus) does indeed have leaves which clasp the stem but of slightly differing shape: oblanceolate to narrowly obovate. Robin's Plantain grows mainly in Southern England and scattered in Britain to West Lancashire). Robin's Plantain has hairy leaves whereas Tall Fleabane has sparsely hairy leaves. The only other difference between the two species are that Tall Fleababe has flowers which are 10-20mm across whereas those of Robin's Plantain are slightly larger at 15 to 25mm across. Hmmm.....


Easily mistaken for : Robin's Plantain (Erigeron philadelphicus) [see the last two photographs of the stem leaves for the differences. (Some of) these specimens may well be of Robin's Plantain rather than Tall Fleabane]

In addition, Robin's Plantain should not be semantically confused with : Robin's Pincushion [a wasp induced gall on Roses]

Tall Fleabane (if the above photographs really are that and not Robin's Plantain) grows in waste places or rough ground on usually sandy soils and occurs mainly in Southern England but can also be found sporadically from Moray down south to Southern England.
