Flowering in August and September, amaze your friends and neighbours with this horticultural wonder! Containing 3 varieties of matching vigour, each with its own flower colour grafted onto the same plant, these totally hardy perennials will provide maximum summer colour impact for many years to come. Usually our growers would graft 3 of the same colour, but in an experimental moment, they created this delightful result! Supplied50 cm (2ft), eventual height and width 120cm x 100cm.
