This massive plant appeared in the border in spring, shot up in no time with huge foliage & is now flowering. The speed & size suggests a weed to me & the slightly tatty look of the leaves & flowers. The flower is a recent picture, the foliage from a few weeks ago, it is larger still now & multiheaded in flowering.

However, I did buy some unusual plants from a plant sale that were unlabelled & I don't want to pull it out if it is some type of perennial sunflower or similar.

Don't know what it is but it's certainly impressive.  It could be one of the dandelion/knapweed/sow thistle group which are common weeds.  If the flowers start to turn into fruiting heads with loads of dandelion-like fruits, whip 'em off and get 'em in the bin/incinerator asap or it'll be all over the garden and neighbouring counties.  In the meantime I should just enjoy it as an architectural plant.

Ah well - there you are.  There's always someone who knows!  Thanks Dove (and congratulations on appearing in print!)

That's excellent, thank you! I knew someone on here would know. 

I may have to move it though, as it's right on top of the David Austin Golden Celebration rose I planted a couple of years ago which is still really low & floppy. It's totally hiding it really! 

Any ideas when the best time to move it would be? It would be a shame to lose it, perhaps I should leave it to seed & collect some & wait until next year then if there are more it won't feel so risky. Or just cut it back hard after flowering, a perennial should survive that I guess.

you can cut it back any time but I'd move it after it dies back in autumn
