Hosta 'Big Daddy' (Plantain lily)
Hosta ‘Big Daddy’ is a statement perennial for shade, grown for its huge, blue-grey, heavily puckered leaves that form a dramatic mound in borders and large containers, bringing texture and calm structure all season.
A clump-forming plant, it can reach around 60cm high (and larger in time) with a substantial spread, making it ideal as a focal point in shady beds. In early summer it produces stems of pale, bell-shaped flowers.
Plant in partial shade in moisture-retentive, well-drained soil enriched with organic matter. Hostas prefer cool roots and benefit from shelter from hot afternoon sun to keep foliage looking its best.
Water regularly during dry weather, particularly in pots, and mulch in spring to conserve moisture. Protect new shoots from slugs and snails, and remove spent flower stems for a tidy finish.
Perfect for woodland borders, shady courtyards and container displays, ‘Big Daddy’ pairs beautifully with ferns, brunnera and hellebores, and provides bold foliage contrast alongside finer-textured plants.
