White Perfection

White Perfection has no recorded origin. No hybridizer, year, or corroborated ADS classification number surfaced, and the negative evidence is worth stating precisely: Dahlia Doctor's listing prints fields for hybridizer, year introduced and ADS classification number and leaves all three empty. That is a seller who publishes registry data looking and finding nothing, which is stronger evidence of absence than a page that simply omits the fields. It reaches gardens through both American growers and the commercial trade, with Ball Seed carrying it as a production line for growers.

White Perfection is the unusual combination of a full dinnerplate bloom on a short plant. Blooms run 8 to 10 inches while every source puts the plant between 40 and 48 inches, which is a useful pairing: most flowers this size sit at 5 or 6 feet and need serious support. It still needs staking, because an 8 inch white head carries a lot of water after rain, but it is far more manageable than a tall dinnerplate. Ball Seed reports it flowers constantly until frost. Heirloom Soul recommends it for large floral installations and for the back of a garden, and reports blooms of 8 to 10 inches on strong stems at 48 to 54 inches. Pinch at 12 inches and give it room. White at this scale marks in rain, so cut ahead of weather.
