Marco Fransen of Fransen Hostas in the Netherlands introduced this non-registered sport of H. 'Halcyon' which, according to The Hostapedia by Mark Zilis (2009), "...it appeared that the leaf center of 'Paradise Joyce' was a clearer yellow color than 'June'. As these plants have matured, however, significant differences from 'June' have become harder to detect."

It forms a medium size (16 inches high x 36 inches wide) mound of ovate shaped foliage with thick substance. Pale bluish lavender flowers bloom from late July into August.

The New Encyclopedia of Hostas by Diana Grenfell (2009) states: "Easy to grow. Makes a superb foreground specimen. Lovely in a container and recently awarded The Newbold Vase by the British Hosta and Hemerocallis Society for the best Fransen introduction."

A Photo Essay article by Steve Chamberlain in The Hostta Journal (2010 Vol. 41 No. 1) makes comments about H. 'Paradise Joyce', "The patented Marco Fransen cultivar is a sport of 'Halcyon'. It emerges with blue leaves that show little, if any, trace of the yellow center to come. As the season progresses, the leaf centers lighten depending upon the degree of sun exposure, reaching an appearance similar to 'June'. Late in the season, the leaf centers become creamy white. This large clump shows a division that has reverted to the all-blue 'Halcyon', which I shall have to remove."
