Coreopsis Verticillata too tall!

I ordered some of these from a garden centre, having read that they’d get to around 60cm and expecting smallish plants to arrive. They are 90cm monsters with all the flowers at the top!  I have planted them but they do look a bit daft in a new border where everything else is quite small at the moment. If I chopped them back by half, will they reflower this year?

    They should if you do it now. I did this in the past around the same time, but admittedly, just before flowering, just to keep them bushier. They definitely flowered.

    Pleased you said that Borderline ; did exactly the same to my Rudbeckia nitida 'herbstonne' yesterday ! Straight across the middle .
    On average they get to around 10' every year , then collapse onto smaller perennials.

    I’ve just cut straight across the tops of Nicotiana, cosmos and rudbeckia.

    Thanks for the replies and encouragement, I will chop it back. It’s always a surprise when I order plants as they rarely conform to stated height and spread!
