Whilst doing my autumn cleanup I noticed that some old flowering stems on a rather neglected Euphorbia characias (I usually cut out the flowering stems once they are past their best to allow the new ones to grow freely) had produced new growth from the seed heads. I suppose this happens in the wild and I think the result is quite attractive. Can I propagate from these new growths? i.e. use them as cuttings? I am never short of "volunteers" but think that plants from such cuttings would be bushier from the start.
