I am propagating the cuckoo flower (cardamine pratensis) from leaves pressed flat onto the soil surface. At every node comes a tiny new plant (seen best just right of centre).
The cuckoo flower is very pretty, comes out at the time the cuckoos arrive and is a food of the orange tip butterfly. I hope to grow them in the long grass and to plant some in Coronation Wood.
I'd love it to look like this photo on this site where I also learned that the leaves are edible and that it can be grown as an acquatic.
