Hosta sieboldiana var. montana (F.Maek.) Zonn.
Hosta montana, Hosta liliiflora
Bloom Time: Summer
Hosta sieboldiana var. montana is a herbaceous perennial that forms large, vase-shaped clumps of broadly-ovate, deeply-veined, olive-green leaves. The leaves have a long, narrow tip and a lightly-waved edge. They are up to 8 inches (20 cm) long and up to 12 inches (30 cm) wide. Whitish bracts surround the flower buds, which open to very pale-purple flowers, carried on stems up to 4.25 feet (1.3 m) tall in late summer.
USDA hardiness zone 3a to 9b: from −40 °F (−40 °C) to 30 °F (−1.1 °C).
How to Grow and Care
The color of a Hosta's leaves can help determine how much light it prefers. Blue and deep green varieties like deeper shade, while variegated (striped or splotched bicolor leaves) and yellowish varieties require some morning sun. Harsh afternoon sun can scorch Hosta leaves.
Hostas prefer an inch (2.5 cm) of water a week, whether it's from rainfall or irrigation. If you water by hand, do so early in the day. Burnt leaf tips and drooping leaves are signals of inadequate water.
Rich, slightly acidic, well-draining soil produces the best Hostas. Add organic matter such as compost, manure, leaf mold, or peat moss when preparing the planting hole. Mix well, and do not let manure contact the roots directly because this can cause discoloration of the leaves.
Apply a 10-10-10 or 5-10-5 all-purpose fertilizer according to package directions if the soil is poor. Otherwise, topdress with well-rotted manure or compost.
Plant Hostas in spring or fall. Bury the crown slightly so it will stay moist, unless the soil is very heavy, in which case leave the crown at ground level. Leave a depression around the plant so that at first waterings, the water soaks directly toward the root. See more at How to Grow and Care for Hostas.
