Looks like obedient plant to me, Physostegia virginiana. Plant Family.......... Labiatae (Mint).

Thanks so much guys. Apparently it's definitely a sheenas gold Duranta and I must have been to about 20 shops to find a large one (above 1 metre to fill the gap in the hedge) :(. Have tried binning a markets nurseries...even posted an ad on gumtree but no luck whatsoever. One nursery offered to ring around but gave up. I live on a busy road and is such a shame to have a gap right in the middle.....grrr. Thank you all for responding....just wish I could find one now...... :)

next time.. dont be afraid of the plant.. and get some closer pix of leaves and stem ... plus this overall one.. if you really want to nail down an Id ken

not bird related ... a bulb either dropped when a bigger clump was moved.. or perhaps a squirrel moved it .. a very long lived bulb.. that will multiply ... in clumps.... not aggressive in moving itself around ... if say ... you planted the daffs ... you may have inadvertently moved the crocus ... they should be no more and 2 or 3 inches under the soil ... one of the very first flowers in my MI ... they make me very happy ... and btw ... flowers are very short lived depending on how warm it is.. when they bloom ... ken https://www.google.com/search?q=crocus+bulbs&source=lnms&tbm=isch&sa=X&ved=0ahUKEwj2kaP_gqTSAhUG7CYKHVOkBNEQ_AUICSgC&biw=890&bih=739
