Crossing the same plants can sometimes give different results. Geranium psilostemon crossed with G. procurrens gave us G. ‘Ann Folkard’, a plant with long, wandering stems of yellow-green foliage and startling dark purple flowers that have an almost black centre. A few years later the same parents produced a more compact plant with similar flowers that was named G. Anne Thomson’. And now we have G.‘Sandrine’, bred in France by nurseryman Thierry Delabroye, which is also less straggly but has flowers that are 5cm wide, twice the size of G. ‘Anne Folkard’. The combination of purple flowers and golden foliage is not for the faint-hearted.
