Halcyon’ forms a large mound of flat, spear-shaped, heavily-textured, blue-green leaves of exceptionally heavy substance and is slug resistant. It is a vigorous grower and is known as one of the best and most popular of the blue hosta. The classic blue spear-shaped foliage makes it very striking. For the most intense shade of blue, grow plants in shade. Plant may be divided every few years or left undisturbed indefinitely. Hosta’s perform well in woodland settings where filtered light is abundant.
