Petasites japonicus var. giganteus (fuki)

🌿 Rare Find: Part of our Rare & Uncommon Garden Plants Collection. Limited availability.

Fuki, also known as giant butterbur, is a dramatic herbaceous perennial grown for its huge, round leaves—often reaching three feet across—and its early-season harvests. Before the leaves fully expand, thick edible stalks and flower buds emerge, prized in traditional cooking for their distinctive, earthy flavor. 

In early spring, fragrant white, daisy-like flowers rise on sturdy stalks, bringing life to the garden long before most perennials wake up. As the season progresses, the plant’s massive foliage creates a lush, tropical look that thrives in moist to wet soils, making Fuki especially well suited for pond edges, streamsides, rain gardens, and naturally damp areas. 

Fuki spreads by thick rhizomes and can be vigorous in open ground. For gardeners who want to enjoy its beauty and harvest without worrying about spread, it also grows very well in large tubs and containers, where it can be appreciated and managed easily.
