What Rockery Plants ?

To start with , I don't have a clue what plants are suitable for rockery type planting . We have a rockery about 9 feet long at the caravan. It is partially planted , but needs another dozen plants to fill it up . Like the one below , can some kind soul tell me what is it ?
Can anyone suggest clumpy type perennials similar to the one below . Long flowering for summer ?
TIA

 

That's Aubretia in the pic.

Clumpy long flowering perennials.
Erodium "Bishop's Form" Recommended.
Helianthum, Rock Rose. Recommended.
Armeria Maritima. Recommended.
Dianthus. Recommended.
Sedum "Spirit" (Bit of a thug, though.)
Mossy Saxifrage.
Mexican Fleabane. (Thuggish too.)
Erinus Alpina.
Lewisia. (Needs extreme drainage)

You can't go wrong with the first four.

 

@kindredspirit , superb listing Kindred They are exactly the plant types I was looking for . I'll have a look in my local GC's for them .

 

Seriously good post @kindredspirit

Not got much experience with rockery plants but can say.... steer clear of campanula carpatica varieties at all costs!

 

why?

 

Doing a quick shop at Aldi this morning and found this Geum Koi for £1.99. A clumpy drought tolerant plant flowering in summer , just the job
I'll be touring the local GC's and Nurseries over the next two weeks with @kindredspirit list in my pocket ( I'll never remember them names ! )

 

@kindredspirit , wel l I have had your list in my wallet for the past 6 weeks . I have about half of the list now , which should be enough for my little rockery. Just bought Armeria Maritima Alba ( Sea Thrift ) today , really like that one
Thanks for the great advice.

Armeria Maritima is a brilliant plant. Will self seed but isn't a thug. The pink and red ones are nice too.

Also there's a smaller form with flowers on one inch high stems, "Bevan's Variety". Hard to get but well worth finding. Forms a tight cushion. Doesn't seem to self-seed, though.

 

Have to disagree with Mowerman....campanula carpatica is a beauty. Forms nice little mounds of blue or white and not invasive
As well as those already mentioned arabis ferdinand coburgi Old Gold is a lovely variegated well behaved plant. If slightly acidic soil check out lithodoras....evergreen with lots of blue flowers in summer. Linum perenne....blue flax....too is a beauty; linum flavum for a yellow companion. Osteospermums may be a tad vigorous for a rock garden but check out Gweek variegated or Silver Sparkler....truly eye catching. Heucheras like Obsidion or Berry Smoothy will give evergreen black or red foliage respectively. Festucas too.......Intense Blue or Elijah Blue will give evergreen glaucous blue foliage and give movement to a rockery as will stipa tennuissima or hordeum jubatum. Carex Testacea will provide evergreen olive/copper foliage. Campanula Dicksons Gold will form a mound of evergreen yellow foliage and blue flowers in summer. Try a couple of gazanias.....hardy down here but planted out in spring will give colour right through to late autumn. Gaura Corries Gold....lovely variegated foliage and sparkling white "butterfly" flowers. I also like Tulbaghias.......fine silver grey foliage and dainty pink flowers. The cheddar pinks.....low mounds of wonderful scented flowers all summer. If warm there try the kudos agastaches.......hardier than the usual types and mound forming yellow, orange or red flowers.

 

Hello Harry, have you thought of mixing it up a little.
There are a small group of Fuchsias which only grow around 10" high. Look out for the " Seven Dwarfs" series. ( I'm sure you know the names Lol ).

There is also a ground hugging Fuchsia which spreads along the ground but only grows around an inch high called Fuchsia Procumbens ( also a variegated form with silver edged leaves called F. Procumbrns Wirral ).

 

Thanks @KFF , I'll keep my eyes open for them . Pretty sure I have not seen them before.
