Hosta ‘Empress Wu’

Hosta ‘Empress Wu’ (Plantain Lily)

Hosta ‘Empress Wu’ (Hosta hybrid) is an impressive perennial known for its giant size and striking foliage, making it a focal point in shaded gardens. This cultivar boasts massive, deeply veined, dark green leaves that can reach up to 18 inches long and wide, creating a dramatic visual impact. The thick, bold leaves form a dense mound, providing excellent ground coverage and a lush backdrop for other plants. During early to mid-summer, pale lavender flowers bloom on tall scapes above the foliage, attracting pollinators and adding an elegant contrast to the greenery.

Reaching heights of 3–4 feet and spreading 5–6 feet wide, Hosta ‘Empress Wu’ is the largest hosta variety available. Hardy in USDA zones 3–9, this plant thrives in part shade to full shade and prefers moist, well-drained, organically rich soil. It tolerates a range of soil conditions but excels in consistently moist environments. Its thick leaves make it more resistant to slug damage compared to other hostas, ensuring its longevity and appeal.

This perennial is surprisingly low-maintenance despite its grand scale. Regular watering during the establishment phase is essential to develop a strong root system. Once established, the plant requires consistent moisture but is relatively resilient to occasional dry spells. Mulching around the base retains soil moisture, suppresses weeds, and protects roots during colder months. Fertilizing in early spring with a balanced, slow-release formula promotes lush foliage and robust growth. Pruning is minimal, limited to removing discolored leaves and spent flower stems. Dividing the plant every few years in early spring or late summer ensures vigorous growth and prevents overcrowding.
