The RHS Chelsea Flower Show opens today until 28th May.
The grounds of the Royal Hospital Chelsea will be transformed, showing off some of the most spectacular garden designs in the world. Let's just hope that Japanese knotweed doesn't feature anywhere at the show!
Originally introduced into the UK as an ornamental plant in the 1820s, the Victorians considered Japanese knotweed a beautiful border shrub. It produces tiny creamy-white flowers in late summer, by which time the stems are up to 3 metres high and extremely dense.
