I have a south facing perennial border that needs an additional plant. The colour scheme is blue and purple. I would like to find something that grows no higher than a meter and looks reasonably compact. It will sit amongst lavender, brunnera, erysimum bowles mauve, aubretia, hardy geranium, purple sage, agapanthus, and purple aster. I would preferably like a long flowering season or at least flowering in August. Does anyone have any suggestions? I have tried salvia a couple of times but it doesn't survive. 

Thank you.

    If your soil is pretty free draining, nothing beats Achilleas that starts from June to August. Plenty of pinks to choose from. And Sedum Telephium Red Cauli and Autumn Joy, both good candidates for shades of pinks and dark pinks.

    Fuchsia?  They come in every shade of pink and purple, and in most growth habits.

    Assuming you wish to stick with blue or purple, have a look at delphinium Magic Spires series.  They grow up to 1m high but you'll need good slug deterrents.

    Agastache rugosa produces purple flowers from summer into autumn and has scented, edible leaves.   Gets to about 80cm high but can be short lived so plan to take cuttings regularly.

    Lobelia Hadpsen purple will get to about 60cm high and flowers from summer into autumn.

    I have a Platycodon 'balloon flower' and it's the most glorious shade of blue.  It might not be big enough to fill the space in your border though, mine is only 30cm tall and wide after 4 years from a cutting.  It's in full bloom now but will start dying back in Sept.

    I also have 2 compact varieties of Hebe, one a deep pink and the other a purple/blue shade. Sorry I can't remember their names.   They both flower throughout the summer although their main flush is late July (in my garden anyway). Evergreen so it doesn't leave a hole in the border over winter.

    Some nice purple dahlias available - get them off to a good start and they can flower June till frosts.

    Aster frikartii Monch or aster Little Carlow. They are late flowerers from August on. But my Monch needs a little support as it can be a bit floppy.
