Rockery plants

I have west facing mature rockery that has become overgrown with persicarius. I have decided to dig it out and replant. I am 67 so I want easily manageable plants that will give ground cover and colour without being invasive like the persicarius.

    That won't be an easy job at all I'm afraid, as I think the roots will have gone right under the rocks. You might have to dig up all the plants you want to keep and pot them  temporarily, whilst you weed kill the whole area, (maybe twice) before replanting. 

    Good luck, I wouldn't want to do it!

    Phlox subulata/douglasii types would grow there. Lots of colours from bluish to very dark red available..

    More hardy geraniums too. They're all pretty straightforward. 
    Spring bulbs under them to give you a succession of flowering, and not much effort needed. They'd all work well with the Phlox too.
    Heucheras would be fine, as long as it isn't too dry. Pachysandra is also good ground cover, but like the Heucheras, it likes a reasonable amount of moisture to do well. Possibly the bit where the wee terracotta pot is, would be suitable  :)

    It's a place where beautiful isn't enough of a word....

    I live in west central Scotland - not where that photo is...
  • I like the idea of the creeping phlox. I have a lot of geraniums so I know they thrive. This is the rest of the rockery:

  • I am making definite, but slow, progress. I am now thinking of putting weed suppressor and gravel in the gaps. This would mean planting more compact plants and ultimately make weeding easier. Any advice? I assume I would have to cut the fabric and fit it like a jigsaw?

    It does not do what it says on the label. Weeds grow through it and are then even harder to remove. Gravel yes, fabric no.

    Weed seeds will find the cracks between the membrane and the rocks, and any weed/persicaria roots left behind will also grow through the cracks (if they don't pierce the membrane. Plus, I think it would be hard to hide all the edges and when they show it just looks tatty.
    Doncaster, South Yorkshire. Soil type: sandy, well-drained
  • So you think no membrane? I was thinking laying it would be difficult To lay. But what about the gravel?
