Hosta Neptune, Plantain Lily Neptune, Neptune Hosta', Blue Hosta, Shade perennials, Plants for shade

Prized for its blue color, Hosta ‘Neptune’ (Plantain Lily) is a clump-forming perennial forming an attractive cascading mound of narrowly wedge-shaped, bright glaucous blue leaves. As the season progresses, the foliage turns more blue-green. Bell-shaped, pale lavender flowers appear on tall, arching scapes reaching 32-39 in. (80-98 cm) in late summer to early fall. The heavily rippled leaves are of good substance, displaying some slug resistance. Moderately fast-growing, this blue hosta cultivar makes a beautiful specimen in the home garden.

  • Grows 24 in. tall (60 cm) and 47 in. wide (118 cm).
  • Performs best in part shade to full shade in fertile, moist, well-drained soils. Shelter from cold, dry winds.
  • This foliage plant is perfect for the shade garden, mixed with other perennials in beds and borders, city gardens, cottage gardens, or containers. Great as a specimen plant or underplanting shrubs and roses.
  • Watch for slugs and snails, which could damage the attractive foliage.
  • Cut off the stems after blooming to encourage the plant’s growth. Discolored leaves should be trimmed back to the ground.
  • Propagate by division in early spring or late summer.
  • Toxic to dogs, toxic to cats, toxic to horses.
