I started these seeds from Chilterns in the UK back in 2018 and they grew so slowly, they just went into the memory garden last year. I had forgotten what they were because the leaves seem very different from the Erodiums I had previously met/grown. These leaves are somewhat coarse and rough. But the flowers look like they will more than make up for that.
My 2020 plans for these plants are to keep them fed and watered and watch how they grow in the coming year, their first out in the exposed garden.
