yes i agree. i'm not goin out to take pics today. it's tippin down! it is definitely greater teasel out there that i have. i'm out this afternoon til about 8.30pm please remind me to go out the back tomoro if i forget about this
you could google teasel leaf/leaves in the meantime, see what images come up
I have been out this morning (rain forecast later today here!!) and triple checked!!
I have photographed the teasels and also the other plant which is the one I think OP has.
The teasel as you know have long ovate leaves but have mauve thistle like flowers on long stalks that then 'teasals'. The greater teasel can grow above 5-6ft in a good soil/situation.
The plant OP has is generally much much smaller than the teasel (up to 3ft), has ovate leaves carried in the same way as a teasel - but when younger much lighter in colour and less tough, but a mass of very very small yellow flowers carried on long stalks. I collect both for my rabbits. In fact I collect the smaller one so much that I rarely see the flowers!!!
Teasal:
Note pointy leaves and size and purple flower with teasal.
Other Plant (which I am positive OP has and which I am trying to tie down!!!) Note that the slightly older plant which is flowering has slightly more glaucus leaves but this IS the same plant as I have them in all different stages. It is much smaller than teasal, the leaves are not so pointed, and the flowers are small yellow on long stalks - typically it reaches about 3-4ft perhaps a bit more if you include flower stalks on a good soil.
EDIT: Lobed-leaf Prickly Lettuce!!!! also known as Compass plant: (Lactuca serriola . . there doesnt seem to be a Latin term for the lobed leaf variation , unless it is Lactuca saligna - (Willow Leafed Prickly Lettuce) though both clearly shown on various websites and books).
SO pleased we had this come up as I have been trying to tie this one down for ages!!!
