There's a *very* pretty Vinca minor called V. Azurea
Flore Pleno with a pretty double flower. I like V. oxyloba too. But for
ground cover, I would very, very strongly suggest Geranium Jolly Bee. This
is a true geranium, not a pelargonium. It has intensely blue flowers and
goes on and on for a very long time. We have some on a bank just outside
the gate and it has spread and covered a large area quite quickly. On the
whole it's better than G. Johnson's Blue, IMO. But Vinca while useful, will
take over and cover everything else, so I wouldn't recommend the two
together. What would look good with the G. Jolly Bee, coming over the edge
of the fenced area, would be Rosa The Fairy. I've seen it described as clump
forming but ours seems to grow in arching sprays which would look very
pretty growing down a wall or bank. There must be other roses that would
look good doing that and so would the perennial sweet pea, Lathyrus
latifolius (unscented though)

Sacha, thanks a lot for these very good suggestions. Have googled
images of the lot. The double-flower of that vinca is attractive. The
Geranium looks really natural. Thanks too for alerting me to the
"everlasting pea" - I always thought sweetpeas had to be replanted
annually!

Eddy.
