The Dahlia Clair Obscur, 'Dahlia Clair Obscur', has velvety rich flowers that are a deep maroon color frosted with white tips. It is considered a cactus type flower because of its wide diameter and petals that stand out in three dimensions. One of the most breathtaking dahlias we offer for the cutting garden. 'Clair Obscur' is sturdy and upright with minimal staking, but will have longer stems and larger flowers if given support and deadheaded regularly. They are hardy zones 8-10, dig and store during winter in colder zones.
