If you had a retaining tire wall.

What would you plant in it?

   

Just knock ideas around. We do need a retaining wall. Not necessarily made of tires. It would be cheap and it could be hidden with lots of trailing plants. I’m thinking for a start aubrieta & thyme. I want low maintenance, low growing trailing perennials. Some evergreens? Fuchsia? Any petunia perennial? Is there a perennial alyssum? As you can see I’m just going through a list of things you’d find in a hanging basket. More flowery gardeners input please.

I have seen tyre walls to hold back the soil where a house is built into a bankside? 

Your new house to be is being built on the flat isn't it SC?

Personally I would just let a tyre wall look after itself and see whatever arrives in the wind? It would also depend on what aspect it was and whether it was shaded or not I would imagine?

You could also, chuck a wildflower mix of seeds at it and see what comes.

I wouldnt grow anything edible

Our finished floor level is lower than the ground level at the back of the house. As we discovered yesterday while studying plans. Also it’ll be very visible from our living room.

Aren't their rules about reusing tyres on land?

Mexican fleabane or some of the more floppy (?) sedums or ice plants, although I'm not sure how hardy they are - although mine have got through snow and repeated nights below -5 this winter.
And hardy geraniums?

No idea, I’d have to look into it more closely.

I've seen them used on one of the Grand Design projects. Not sure whether it was in this country or not though. It looked like very hard work as each tire had to be rammed hard with soil before the next layer could be added.

Alyssum saxatilis is perennial.

If it's going to be visible from your living room what about rendering it? You could leave the top open and plant it up with trailers?
