With deep burgundy petals dipped in white, 'Mystery Day' Dahlia?s double blooms deliver an unexpectced surprise to every passerby. Each full, plate-sized flowerhead measures up to 10" across and features slighty-rounded petal edges. 'Mystery Day's blooms are complemented by healthy green foliage and loads of nearby buds, each at a different stage of unfurling - be sure to steal some for the vase when you're out cutting flowers!
