I got impatient.

      SO - I shall, therefore regard this as a "First sighting"; even if it gets a second look after fully open.
     This is the Hellebore which hasn't, as far as I can recall, flowered for so long I genuinely thought it dead.  This has come to light since "Worral" & Mary moved in next door and "de-vegetised" their front garden.
      I misremembered the colour though.  I read recently in either Jerra, or Clicky's Blip that they had a yellow Hellebore; and I misremembered this as yellow, it's so long since I'd seen it.
