I have just built a retaining wall (about 2 foot high) in my son's
garden. It faces south and we are looking for something to trail down
over the brickwork. Whatever we choose will probably need to look after
itself, but not spread too much. Aubrieta springs to mind. Dianthus
alpinus, Geranium cinereum, Helianthemum maybe? Any other low
maintenance suggestions? TIA

Some of the rosemaries look wonderful trailing over a wall in a
not-too-cold garden and lavenders billowing out are most attractive. We
have a double Silene maritima which trails down from pots on pillars.
It dies back each winter but we leave the trailing stems and sure
enough, they burst into life again every spring and have done for
around 5 years. It's also slightly scented, which is a great bonus.
The other thing which is extremely pretty is the small flowered Vinca
minor GertrudeJekyll. It's nothing like as thuggish as Vinca major and
makes pretty, free-flowering clumps.
