Very nice Sacha - looks very much like 'La France'. It is vigorous
enough to do that and was very widely grown 15 - 20 years ago,
appearing in almost every hanging basket. 'Mexicana' (red and white
semi-double) and 'La Roulette' (crimson semi-double) are as vigorous
and I've grown both as 8ft. pillars in big planters outside.
