my hardy osteospermums are in full flower...have been for a few weeks now....and will continue well into November.  Well, hardly ever without a flower.

agastaches start soon and just don't stop.

    erysimum bowles mauve has had some sort of flower on all year and will do for the rest of the year. Rudbeckia goldstrum flowered for ages last year also

    Geums and some of the geraniums go on and on hereimage

  • Wallflower Bowles Mauve for me too. Around 10 months flowering but sadly then they died! Lasted only 2 years. Must've exhausted itself.

    Our Nepeta seems to flower for months on end once it starts.

    Whats your secret with agastache Verdun? Was disappointed with mine last year. I'm Surrey and chalk/flint...

    Hi Chicky!

    Me too! I pulled 2 out and set them up in recovery pots over the winter as they were on their last legs, I've only just replanted them back, slightly recovered! Fingers crossed ...
