Hosta 'Halcyon' Halcyon' is one of the best blue-leaved hostas. It has medium, glaucous blue leaves that are lance-shaped when young, becoming to heart-shaped when mature. For the most intense shade of blue, grow plants in shade. In summer, the foliage is complemented by the bell-shaped, greyish-lavender flowers. The Royal Horticultural Society has given it its prestigious Award of Garden Merit (AGM) which is for plants of outstanding excellence.
Hosta 'June' --From England comes this wildly popular, creamy-centered sport of the old standard Hosta 'Halcyon'. Each leaf emerges with blue edges and a brilliant creamy center that gradually changes to dark chartreuse. This is one of those shockingly beautiful hostas that stands out as soon as you spot it in the garden. We recommend some morning sun for best coloration.

"June" hosta, one of my favorites, is lutescent, meaning it's color lightens with more direst sunlight. This is at the very shady end of the 'June' spectrum. At the other end, lighter blue-green leaves have light yellow-white streaks out to the leaf edge. In the PNW, 'June is a late Summer bloomer, sometimes as late as September.
