Breaking dormancy remarkably early, this colossal hosta quickly unfurls massive blue leaves edged in wavy yellow that soften to creamy white by summer. A sport of award-winning Empress Wu, Gigantosaurus develops an extraordinary 6–6½' spread, adding strong architectural form to shaded borders or oversized containers. Pale lavender flowers rise just above the foliage, and the broad, overlapping leaves form an impressive, weed-suppressing ground cover.
