The forecast last night was for an overnight frost that would clear quickly. How right the forecast was, bright sunshine soon warmed the ice crystals with damaging consequences to the Viburnum bodnantense cultivars. The attached image shows the rapid browning and discolouration that occurs to the open flowers when direct sun expands the frozen ice crystals within the petals.
