Joyfulness  Released by Tantau in Europe as a floribunda. What a joke!  Most stems bear only one bud. Good sturdy grower with nice long straight stems. Colour is hard to classify. Perhaps a soft coral salmon is close, but does not include the golden highlights. The ladies adore the colour. May give an occasional specimen bloom but a large arrangement or an exhibition bunch would be a sensation.

[This reference may be for 'Joyfulness' (floribunda, Tantau 1961).]
