Powdered blue giant with heavily corrugated leaves and stately near white bell-shaped flowers during the summer. 'Blue Mammoth' works well as a specimen or as a mass planting in a background setting. This massive hosta can reach 5-feet across at maturity.
This mounding Hosta with moxie grows to 3ft tall and 5ft wide, and the heavily puckered, powder-blue leaves have a span of 12in. Flower stalks rise to 4ft and are topped with many pale lavender flowers. A giant worth making room for.
