Hogweed is back - and Hemlock

Now that the cow parsley has gone the Hogweed is the next umbellifer to come into flower.  It grows twice as tall.

Even taller is Hemlock, another umbellifer, but with much more delicate leaves and flowers.  (you won't confuse it with cow parsley or pignut, which are pretty well over by now)

The really clear distinguishing feature of Hemlock is the purple spotting on the stem.  

THIS PLANT IS POISONOUS and was famously used in the execution of Greek philosopher Socrates
