Covent Garden goes back to its roots this week when the inaugural Flower Festival celebrates the area's tradition as London's premier flower, fruit and vegetable market. The market dates from the middle of the 17th- century when the Earl of Bedford was granted the right to hold a market for "flowers, fruits, roots and herbs". And so it all began. But everything hasn't always been rosy in the Garden. As the area prospered, congestion increased, driving the wealthier residents out to be replaced by the traders and an assortment of underworld characters. Matters came to a head in the early 19th-century, only to be resolved with the demolishing of the traders' booths and the building of Charles Fowler's covered central market.
