Originated by Jan van den Top of the Netherlands and registered by  Danny Van Eechaute of Belgium in 2004, this cultivar is a sport of a streaked form of H. 'Beauty Little Blue'. It was granted a U.S. patent in 2008. 'Little Jay' is a miniature size, rhizomatous plant growing to only 3 inches in height and 7 inches in width. Leaves are narrow (lanceolate), slightly rippled, dull on top and tapering to the tip. The lavender flowers bloom from June into July.

The Book of Little Hostas by Kathy and Michael Shadrack (2010) says: "Too much sun in warmer climates may burn out the center of this pretty variety, the best and most attractive of this type and ideal for containers and troughs."

The New Encyclopedia of Hostas by Diana Grenfell (2009) states: "Soon exceeds its registered dimensions. One of the best and most attractive hostas of this type. Grow with H. 'Mighty Mite' for contrast of leaf shape...The blue-toned green leaf edge looks its best early in the season. The leaf widens and flattens as it matures, the lobes becoming tapered."
