Hosta sieboldiana var. elegans (Blue hosta)
Hosta sieboldiana var. elegans is a classic shade perennial prized for its bold, heavily textured foliage that adds structure to borders, woodland gardens, and large containers from spring right through autumn.
Forming a broad, clump-forming mound, this hosta develops blue-grey leaves that become even more impressive as the plant matures, creating a strong backdrop for neighbouring flowers and underplanting.
Plant in fertile, moisture-retentive but well-drained soil in a sheltered spot with partial shade. It performs best where the ground stays evenly moist, especially during the first growing season.
Water regularly in dry spells, mulch in spring to conserve moisture, and remove tired foliage as it dies back. Protect emerging growth from slugs and snails, and divide congested clumps every few years.
Ideal for shady borders and underplanting, hostas also provide valuable cover for beneficial wildlife and bring a calm, architectural feel to planting schemes where flowers can be harder to achieve.
