I have a bed in the rain shadow of the eaves, but where a plant can
run its roots sideways a couple of feet to where there is ample

and Cyclamen coum (which love it!) It faces north-east.

The C. cirrhosa doesn't flower much, and is becoming a nuisance,
so I would like to replace it by something with a maximum height
of 10-20'. There are wires for the first 10', so self-clinging
is not required. Either evergreen or flowers.

But the key is that it must be happy with NO direct rainfall!
And, of course, take moderate frosts (hard by West Country
standards, mild by Highlands ones).

Tropaeolum ciliatum should do what you want. But, be warned, it is very
invasive, and runs underground! Frosts above ground will damage the
plants, but the tubers will survive deep underground.

I grew it once, and it survived over 5 years of glyphosate. When I
tried to dig it up, some of the tubers were more than 40cm down up
against the footings of the house. I am sure they would have gone
deeper if they hadn't hit concrete.

On an unrelated matter, some time back you asked for suggestions for
exotic veg. I just came across this page.

You may have seen it, but if not maybe there is something of interest
for you.
