bush with three-lobed leaves ID'd by John J as Brousonnetia papyrifera

Could anybody please help me with the identification of this bush covering the hillside along the Akropoleos street between the old city wall and the church Agios Pavlos in Thessaloniki? The vegetation was quite dense, so I couldn’t see what the trunks were like, the leaves were large, three-lobed, serrate, greyish-green and possibly slightly hairy. I have searched the internet and the only leaves I found which look similar were those of the tree marigold, Tithonia diversifolia, but I have never seen that in Greece and it is most likely something else. No flowers yet.

Jorun, the only thing that comes to mind when looking at those leaves is
Brousonnetia papyrifera
. Could they have been cut down to keep them growing low? Sorry, that's all I can come up with.

Thank you, I believe you are right, John. I found a reference to this in an article 'The vascular flora of the Byzantine Walls of Thessaloniki' Nikos Krigas, et al. (Willdenowia, 29(1/2):77-94).
Published by the Botanic Garden and Botanical Museum Berlin (BGBM) ,

Here it is described as one of the 28 xenophytes which are successfully established and well represented in the surroundings of the wall. It is not mentioned as a threat in any way, although it is described as a terribly invasive weed in many other countries.
