Rooted forsythia cuttings (Hearthstone DE4)

I finally got around to cutting back my huge forsythia, and found that several branches had put out roots where they touch the ground. So if you want a lovely, hardy, (and eventually large) bright-yellow-flowering bush that needs no maintenance beyond a bit of pruning, let me know. I've endless cuttings (and can supply a willow twig to make hormone rooter to ensure it sprouts in a cup of water) or I've got about 4 twigs that already have established roots (see photo). All will be female/flowering plants, as they are effectively clones of mine that is covered in yellow blossom as the garden wakes up each spring.

For collection from Riber, near Matlock. Sooner the better!
