...Hoes were not used in the ornamental garden [of Sir Frederick Stern]; weeds were controlled by hand with the result that interesting seedlings were preserved.

Being manager of a large nursery at the time, I was also on the lookout for seeds of potential worth and spotted an entry for Anemone pulsatilla (now (Pulsatilla vulgaris) 'Mrs Van der Elst' in Thompson and Morgan's seed catalogue soon after the Second World War. I had heard of this pink form but had never grown it. A packet of seeds produced a majority of pink forms of really good colouring. I took two or three to Fred Stern. He was surprised and delighted and I came away with young plants of Paeonia emodi and P. veitchii, which I still have.
