- The plant found favour as a large ornamental in parks in the late Victorian

- Indeed it is having escaped from parkland the species colonised the banks
- of many UK waterways and is very resistant to chemical controls. Most local
- authorities now opt for a control method cutting and burning the plant before
- it flowers. The plant is notifyable in the UK as indeed the sap is highly
- dangerous especialy as the stem forms into hollow "pea shooters".
- My advice would be to dispose of said seedlings ASAP especialy if you have
- chilren .

- Two related notes
- Several years ago there was a caseof alleged child abuse in the UK where two
- chilren were found with marks similar to cigarette burns over their bodies.
- It then transpired that they had been using the stems of an Umbellifera as
- pea shooters. Was this also G.H. or are other members of this family toxic
- to varying degrees?
-
- For a semi-humurous account of the species and its history listen to the Return
- of the Giant Hogweed by Genesis (on either Foxtrot or Nursery Cryme) it was
- written at about the time the extent of the problem was realised in the UK
