Hosta 'Blue Mammoth' - 2026

Hosta 'Blue Mammoth' is a hardy perennial admired for its enormous, blue-green leaves that form a broad, mounded clump, creating a striking focal point in shaded garden areas. The large, slightly corrugated leaves provide dramatic texture and structure, while upright spikes of pale lavender flowers appear in midsummer, adding height, seasonal interest, and attracting pollinators. Its impressive size and bold leaf colour make it ideal as a specimen plant or for adding visual impact to borders and woodland gardens.

Thriving in partial to full shade with moist, well-drained soil, 'Blue Mammoth' is hardy, low-maintenance, and reliable. The ornamental foliage maintains its striking appearance throughout the season, while the summer flowers enhance garden biodiversity. Its combination of substantial leaf size, rich blue-green colouring, and seasonal blooms makes it a standout choice for shaded planting schemes.
