Not a Scooby

Haven't a clue what these are - spotted them growing by the side of the road down to Aros Park.  Don't think you'd want them in a bouquet, there was a bit of a stink and I wasn't sure if it was coming from these or the bog they were emerging from.  They look like aliens.

Blipping late as just back from the Tidal performance - really enjoyed it - well done everyone who was involved.  Might have to go back for seconds.
