Looking for ideas... low growing perennials

I'm looking for some ideas for low growing perennials that I can plant around the base of my roses. At the moment I have lots of forget-me-not (FMN) growing around them and that's fine, except they die off... I'd like something a little more permanent along the same lines. I have lots of perennials around but I particularly like the way the FMNs grow densley and not too tall. Penestemon are too tall for most roses though I have lots of them as space fillers. Needs to be able to cope with a dry summer and freezing in winter. The roses with the FMN under them always do better than the ones without so I'd like something shallow rooted that can grow right in and around the rose trunks. I have grown lambs ears around them before and don't like the way they die off. I have tried seaside daisies but they grow up the trunk and get too high... thinking I might try Snow in Summer and see how that goes. Would like it to spread by runners or by division. I have chamomile too and really like this option. Yarrow gets too high in a rich garden bed but is also nice.

Nepeta works fairly well. It grows about the same height as seaside daisies but just fans out from its centre. I cut it back very short in the winter when it goes daggy, then it comes away again in the spring.
I also have pansies that self-seed each year. They hang around flowering all year.
I also have something like snow in summer that flowers nicely in the spring then continues as a slowly spreading ground cover the rest of the year. I have tried to strike it to increase it in the garden but it always fails. I don't know how to do that proplerly.

Catmint!!! That would be good. What about livingstone daisies? Are they annuals? The FMN self seed all over the place and come up like weeds (I pull them out like weeds too )... a perennial FMN would be good

Dee... does your snow in summer-like plant have yellow flowers instead of white? there is one like this around that also looks really nice but I don't know what it is.

What about violets? They are hard to get rid of once you have them though and my chooks love them

Alyssum looks really pretty amongst the roses - there are several colours to choose from and it doesn't get too tall.

Violets really like a shady bed - I have them under my treeferns. I think the roses wouldn't provide enough shade for them.

I don't know the yellow flower Simon, mine is white and I am not sure if it is the official snow in summer either, it just seems a good name for it.

Isn't Alyssum an annual? I have prostrate clematis, penstemon, geranium, potentilla, a prostrate mint bush, a prostrate ceanothus, aquilegia, alstromera, daisies, crocosima, dierama, bearded and Dutch iris, lemon balm, chamomile, lupins, peony (tree and bush), carnations, lavender, sisyrinchium (yellow, blue, and white - these are really nice... I have one called 'Devon Skies' that I'm going to put around as many roses as I can) and a few others through the gardens now... but am looking for a perennial that spreads by layering/runners/stolons etc that will form a dense weed excluding buffer around the rose trunks... I'll take a photo tomorrow of the forget-me-nots around the roses to explain what I mean. I have a lot of cuttings in of a dwarf pink lavender called 'Fairy Floss' that gets to about 30cm tall that I'd like to put around but again... it doesn't spread and run.

Keep the ideas coming

Was thinking of Thyme too... anyone use this?

Yes, Simon, Alyssum is an annual, but it's self-seeding so it's always there.
FMNs are the same, aren't they?

They self seed well enough but they seem to peak and then die off allowing plenty of time for other adventitious weeds to jump in.

Diascia are nice and very tough. Drought resistant, frost resistant, nothing bothers it. All you do is cut them back when the flowers start to finish , give it a feed and off it goes again. Doesnt spread or run tho More a clumper like catmint
Pigface?..bit garish(sp?) for roses..

hmm have to keep thinking..

There's a ground cover campanula that spreads nicely, also a low growing dianthus that forms a dense green mat, then has neat little red flowers in spring.

I used to have a purple ajuga in a rose bed, an idea I saw at Tesselars display garden in Melbourne, but its too enthusiastic, unless you have the patience to rip it out around the base of the roses so they don't get throttled. It does form a dense weed mat though.

Yeah... I was thinking of Ajuga too... I have a lot of it here in along a path... I don't know that I would bother pulling it out from around the rose as this is the effect I am trying to achieve... cover right up to the trunk and believe roses (at least here because the soil is very friable and deep) can cope with crowding with shallow rooted groundcovers. I was looking at campanula in the GE cat. that arrived yesterday too thinking it looked pretty good for what I want as well... hmmm

The ajuga type that I had strong connections between the plants that got very tight around the roses. I was afraid it might damage them, but perhaps they would have been OK anyway.

the campanula is quite easy to multiply with cuttings and division after you get it .

This is the forget-me-nots around 'Mary Rose' and 'Maurice Utrillo' (note all the new growth on 'Mary Rose' already... think I'm going to shorten the left a bit to even her up but she's even got a flower on her atm)... sorry about the poor pic... was taken with the point and shoot pretty much in the dark. The grassy looking plant infront of the FMN is the sisyrinchium.
