Plantain Lily

Plantain Lily (Hosta spp.)

Hosta, Funkia

Part shade to full shade; medium to moderately moist moisture; adaptable to a wide range of soils including clay; moderately acid to neutral pH.

6 inches to 4 feet tall and wide depending on cultivar (miniature through giant); blooms in summer with lavender or white tubular flowers on scapes above the foliage; foliage is the primary ornamental feature — blue-green, gold, chartreuse, or variegated; spreads by rhizomes to form expanding clumps.

Divide in early spring or late summer every 4–5 years; clumps can remain undivided indefinitely but crowding eventually reduces vigor.

Native region: Not native to Tennessee; ornamental introduction from Japan, China, and Korea.

Hosta is the default shade perennial for Middle Tennessee and performs reliably across the wide range of shaded sites found in Columbia and Maury County — north-facing foundations, tree canopies, and woodland margins. Blue-leaved cultivars ('Halcyon', 'Elegans') retain color best in heavier shade; gold and chartreuse types ('Sum and Substance', 'Gold Standard') require brighter indirect light to develop full color. Deer and slug damage are the two consistent problems: deer will browse hostas to the ground repeatedly unless deterred, and slugs shred foliage in wet springs — iron phosphate baits are effective and low-toxicity. The summer heat and humidity of Zone 6b/7a do not stress established hostas provided soil moisture is consistent.
