This week is British Flowers Week - but did you know only 10% of flowers sold in Britain are grown here? To highlight this fact, and to celebrate our home-grown flowers and foliage, New Covent Garden Flower Market launched British Flowers Week in 2013 to promote British flowers, their growers and the independent florists working with them. One of those independent florists is Agent F, whose bouquets are a riot of colour and who I first met just before Xmas when I made a festive table centrepiece with them.
