Thomas Sanderson's first RHS show of 2013. The prestigious Royal Horticultural Society kicks off its year with one of their smaller shows, but it carries the same impact none-the-less. Visitors to this year’s Cardiff Flower Show will be left in no doubt that spring has sprung in full colour this season. The showground is ablaze with colour and vibrancy and surrounded by the exquisite blossom filled grounds of Bute Park. The floral marquees are packed with spring classics, gardeners’ favourites and some real botanical treats. It’s a pick 'n' mix designed for plant lovers and the variety on offer is astounding.
