Clumping Perennial ideas

I planted a few Totally Tangerine Geum and Anthemis Tinctoria E.C. Buxton last year and they have already spread quite a bit.  I still have a decent amount of bed that I would like to cover with other perennials which will clump up and provide a bit of ground cover.

Would it be possible to get the names of a few other perennials which will clump up and cover weeds and bare ground relatively quickly?

    Erysmum Bowles Mauve grows fast but you would need to replace it after about 3years. Cuttings are easy

    The obvious answer to this question involves a hardy geranium of some variety.

    Centaurea montana

    A single Geranium Rozanne will cover an are several feet across in summer, although it is dormant in winter.

    London pride,  Saxifraga x urbium, and Sicilian chamomile, Anthemis punctata  Both evergreen, hardy, spread themselves without running riot.  Full or partial sun.

    Ajuga reptans, can be a bit invasive when happy, great for the bees.  Lysimachia numularia will also cover quite a bit of ground, especially if your soil is reliably moist, but that too can be quite invasive.

    The 'daisies' will form good clump sat this time of year, and will give a succession of flowers - Heleniums and Rudebeckias. 
    Lychnis is also good. Wild rocket is excellent, and virtually evergreen.

    Euphorbias as well - just be careful you don't pick the slightly invasive big ones.  ;)

     You already have my favourite evergreen clumper with geum Totally Tangerine. I like it planted alongside hardy geranium Brookside. It is a great blue geranium that clumps up neatly, doesn't seed around, it's not evergreen but has lovely red tints to its leaves in autumn. Divides easily too.
     Hardy geranium Rose Claire, potentilla Miss Wilmot, francoa sonchifolia, hardy geranium Biokovo are all evergreen for me.
    Prunella Grandiflora is good for groundcover, the bees adore the flowers. Helenium Hoopsii stayed evergreen and is a nice clump now.

    Persicaria amplexicaulis is a strong grower, you could divide it at the end of the year and help it increase it's spread by replanting as a group of three. It eventually forms very big clumps that outcompete everything else. 

    Salvia 'Purple Rain' has been vigorous for me, each plant grows to maybe 2ft across with big ground smothering leaves. 

    Grasses! Sesleria autumnalis has been a really good clumper. Small divisions become decent plants by high summer. Great foil for summer flowers and lovely white rocket flowerheads. Luzula nivea is a great spring flowering grass for semi shade that also clumps up fast. Neither of these leave any space for weeds. 

    I wouldn't call it a clumper or ground cover but Sedums are very easy to increase through propagation; do a Chelsea chop and every stem can be used as a cutting, and the leaves you strip from these cuttings will also form roots if you push them into compost.

    I'd add heucheras, penstemons, veronica, peony, thalictrum, stipa gigantica and heleniums
