Gardening, says style icon Carolyn Roehm, is just like love. you fall for something, end up being disappointed when it doesn’t work, then have a mad love affair with the next idea. For Roehm, who was mentored by Oscar de la Renta before launching her own fashion house in 1985, the gardens of her historic Connecticut residence have always been a source of inspiration. She draws from them for her trademark tablescapes, her gracious dinner parties and her art-quality photographs.
