The Chelsea Flower Show, the world's most prestigious and anticipated horticultural event, began in London on Tuesday.

Now in its 107th year, the show boasts a garden designed by Catherine, Duchess of Cambridge, and has already welcomed royalty to tour its impressive displays.

More than 150,000 visitors will attend the show this week, exploring traditional designs alongside gardening's newest trends. The event runs until Saturday.
