Bluest in spring.
Hosta 'Neptune' is the result of a 1999 cross between seedling 97-316 ('Maekawa' x 'Halcyon') and 'Salute'. It forms a medium to large upright clump of wedge-shaped blue-green leaves that are wonderfully rippled and cascade downward. Lavender flowers open during August on arching stems. A stunning specimen plant frequently commented on in the garden.
