A sport of H. 'Grand Tiara', this cultivar was registered by Walters Gardens, Inc. of Michigan in 1998. The margins of this medium size plant start the season yellow and then turn creamy white later in the year. It bears purple flowers in July.

According to The Hostapedia by Mark Zilis (2009), "In my mind, 'Grand Prize' rates as the best of the Walters Gardens 'Grand Tiara' sports."

The Book of Little Hostas by Kathy and Michael Shadrack (2010) says: "An outstanding small hosta. Dappled shade will maintain the excellent color contrast."

A Photo Essay article by Steve Chamberlain in The Hostta Journal (2010 Vol. 41 No. 1) makes comments about H. 'Grand Prize', "Walters Gardens registered this wide-margined sport of 'Grand Tiara' in 1998. Since it is slightly stoloniferous (Mr PGC - Hostas are rhizomatous), it forms an every-widening low mound as it matures. For a time after the leaves emerge, the color contrast between the green center and yellow edge is particularly striking. Late in the summer, the leaf edges lighten to white."
