Valyrian Steel Hosta

Quart Size

Hosta 'Valyrian Steel' is a distinctive blue-leaved hosta cultivar known for its large size, rippled foliage, and pale lavender flowers that bloom in summer. 

• Leaves: Large, elongated, aqua-blue leaves with tightly rippled margins, forming a substantial, semi-upright mound. The foliage is thick and resistant to slug damage.
• Flowers: Produces pale lavender flowers on showy stalks in the summer.
• Size: Matures to approximately 25 inches tall and 50 inches wide.
• Origin: A cross between 'Neptune' and 'Blue Mammoth' hostas, hybridized by Dan Wols.
• Growth Habit: Forms a mounded clump.
• Hardiness: Hardy in USDA Zones 3-9, according to Hostas-Store. Monrovia lists it as hardy in zones 3-9. Other sources suggest hostas generally thrive in zones 3-9.

• Light: Prefers light shade to shade; filtered sun is best for optimal color. Blue hostas are particularly shade-tolerant, according to EUROHOSTA. Too much direct sun can cause the leaves to turn green-blue or even fully green, and potentially scorch or bleach the leaves, notes Southern Living.
• Soil: Thrives in moist, humus-rich, well-drained soil. A slightly acidic to neutral pH (6.0-7.5) is ideal. Avoid heavy clay soil.
• Watering: Needs consistent moisture, especially during dry spells, but avoid overwatering. Deep watering once or twice a week is usually sufficient.
• Mulching: Applying a layer of mulch helps retain moisture, suppress weeds, and regulate soil temperature.
• Fertilizing: A balanced, slow-release fertilizer can be applied in the spring, but adding compost or well-rotted manure yearly can also suffice. Avoid fertilizing after July.
• Pests and Diseases: While relatively resistant, they can be affected by slugs and snails. Deer are also known to browse on hostas. Diseases like Southern Blight can also occur, particularly in warm, wet conditions. Good airflow and avoiding overwatering can help prevent fungal issues.
• Winter Care: Hostas are hardy and go dormant in winter. After the first hard frost, remove dead foliage. Applying a layer of mulch can help insulate the roots, especially in colder climates.
