Some of the most picturesque American roses (to my British eyes, at least) have been encouraged to clamber over fences. That’s how Rosa ‘Red Cascade’ managed to sneak its way into my heart. If ever a rose was destined to make a plain fence seem more interesting, this is it. The first time I noticed it growing was in tough conditions, in full sun, on a mesh fence, in a graveyard in Jackson, Mississippi. If it had been flowering at all, I’d have been impressed, but this plant was liberally covered with red blooms.
