The flower color is light purple with a purple-red center. A special feature is that the plant blooms from the bottom up. The plant is available from September for garden centers and traders in a 2 liter rose pot with 90 cm bamboo stick. PROUD MARY was bred by J. van Zoest BV from Boskoop, the Netherlands, who also sells the plant and submitted it for the Novelty inspection. Protection under Plant breeder’s legislation has been applied for.
