My wife asked me to find an evergreen climber for an arch which we have
just replaced. I thought the choice would be pretty large, but that
isn't the case. Just about all are white-flowered, maybe cream, but good
colour is very rare. The plant would get sun all day, and would be about
3 metres from a south-facing wall. FWIW, I'm in south Hampshire and the
soil has a fair amount of clay in it.

There are a couple of Loniceras, and maybe Holboellia (but is it hardy
enough?) which might do. But the only one which seems truly hardy and
otherwise fits is Rubus henryi. But that may be a bit vigorous, and one
reference states that it spreads by root suckers! At a pinch,
Passiflora caerulea /might/ survive, but I doubt that Mutisia oligodon
or spinosa would. We already have Clematis cirrhosa, and Clematis
armandii Hendersonii rubra is nearby.

Does anyone here grow Rubus henryi? Does it spread?

Anyone got any suggestions for other plants which fit the bill?
