Hi, I don't think this is a species in it's own right, so I think you may have to do root cuttings in winter to propagate it, if it was a species you could save the seed and sow from late spring to early summer, or you could divide in spring, either way, it's too late for this year, sorry, you'll have to wait for winter, Derek.

i have tried the seeds and yes your right i get an inferior phoecium type smaller runts with single spires in shades of pink that why i decided the only way of propergating was root i want lots of them as this is a colour not often seen in spring

sorry its not Cleopatra it clementine but the same advice stands
