About Sinningia 'Duchess of York'

Sinningia 'Duchess of York' · also called Duchess of York gloxinia · flowering

Sinningia 'Duchess of York' is a hybrid florist gloxinia grown for huge, double, ruffled bell flowers in red edged with white. The velvety, tuberous gesneriad blooms over weeks indoors, then dies back to its tuber for a winter dormancy. Give it bright indirect light, even moisture, and warmth to coax repeat flushes.

Mature size: Around 20-30 cm tall and 25-30 cm wide in flower.
