What to plant in (very) narrow/shallow border?

I've got a narrow gap (approx 6 inches wide) at the base of my fence which runs along the side of the drive. I plan to top it up with compost and get some colour in there.

I do get a few Muscari and other bits popping up each year but I would like flowers in there from April through to September

Any suggestions for bulbs/seeds which will grow in a narrow space would be appreciated

It's South facing but in part shade as there are mature trees shading it. It gets more sun at the end closest to the road.

 

Is it allowed to spill over? If so, what about thinks like trailing lobellia, thyme, that ground covering campanula or anything that. I'm thinking the sort of plants that people jam into dry stone walls, which I think look brilliant.

 

If you have nothing the other side, ie the neighbours side is the same as yours, how about houtinnia Cordata chameleon??

Lovely variegated foliage in red and greens, grows about 6 inches or thereabouts tall with little white flowers. Is very vigorous too so will cover that space in no time!

 

Thanks both for the suggestions

clueless - preferably not spilling over as I'll step on it when I get out of the car.

Al - got some of that in my front garden which I'm forever trying to get rid of.

Am thinking more along the lines of annuals so I have flowers all spring/summer.

 

I agree low growing campanula as it will cope with the dry conditions , I think thyme would need more sun to flourish but if so would be great as well .

Saxifrage may be suitable as well

Spruce

 

I do have some alpines (including Saxifraga) which I could shove in there which are currently in pots. May put some seeds in there as well.

 

Calandrinia is a great burst of summer colour!

Personally I would maybe be thinking about a variety of different Sempervivum species. Hardy, drought tolerant, multiply freely with unusual flowers. Great foliage all year round too.

 

Thanks for the suggestions re alpines.

I'm going to plant out the five I have already and see how they get on interspersed with some seeds.
