Alien plant-life discovered

I was picnicking in Bushy Park awhile back when I came across what could only be described as some very strange Stalagmites. The woody protrusions were like nothing I have seen before.

Perhaps they are the roots of a tree or the remains of a heavily pruned bush... or perhaps our world is being slowly and covertly overtaken by a strange alien root monster that is pushing it's legs throughout our world...

Check your gardens, be on your guard. These things could eat the triffids for dinner and have you for afters. Ahh.

* UPDATE* – Apparently these are the roots of an unusual Conifer plant – the Bald Cypress or Swamp Cypress (Taxodium distichum) – which has roots projecting above ground and are for the plant to breath.
