Anyone recommending erigeron and hollyhocks as companion plants would draw a few strange looks because of their disparity in habits, but they do look strangely suited in this pavement garden.
The erigeron is gently spreading where it can, close to the wall, in the cracks between stone pavements. The bruising footsteps of wayfarers weed any straying youngsters from the main path. Towering above are hollyhocks – not your defoliated, rust-blighted type, but clearly getting enough water and nutrients from somewhere.
Can this be as effortless as it looks? Are the hollyhocks perennials, do you think, companionably self-seeding a few more colours each year and sturdy enough to stand upright without staking, or is there an artful hand at work?
