It's very hard to show just how big Giant Hogweed really is. Generally, if it is 10 feet tall, that's it. By Friend's Bridge (the red one) there has been a patch of them by the side of River Lea for many years. This gives an unusual opportunity to look down on them. I've put together a sequence of photos taken from 2010 to 2015 showing the plant's development.

This is a dangerous plant. Touching it makes the skin light-sensitive, producing horrible burns when exposed to sunlight.

Over the past few years, LVRPA have started to take action to kill them, but they can still be found all along friend's path, on the oxbow, and of course on adjacent land. Last year, there were a lot growing around the reservoirs.

This sequence has also appeared on iSpot.
