Re: [IGSROBIN] Geranium psilostemon (large geraniums)

In Alan Bloom's Dell Garden at Bressingham in England I once saw 'Ann
Folkard'  scramble about 6ft up into a shrub, an escallonia I think. It was
planted about 6ft from the base of the shrub's stem. It also made about 8t
across and threatened to bring the whole shrub crashing down - but it was
spectacular.
