Gunnera manicata
Gunnera manicata, also known as Giant Rhubarb, is a striking perennial celebrated for its impressive foliage.

It thrives in partial shade and consistently moist, boggy soil, making it ideal for damp garden areas. Hardy in USDA Zones 7-10, it can be grown as an annual in cooler climates. For Zone 7, winter protection with mulch is recommended. This unique specimen ships as a bareroot crown, ready to establish a dramatic presence in your landscape.

What customers say
Customers view the Gunnera manicata purchase as a high-reward, high-risk investment. White Flower Farm delivers healthy starter plants with excellent packaging, minimizing transit issues. Successful buyers praise the plant as a magnificent, architectural centerpiece that grows vigorously in ideal, moist conditions. However, a key theme is the difficulty in establishing this perennial. Due to the premium price, some buyers feel disappointed by the initial small size. The primary hurdle appears to be the plant's demanding environmental needs, leading to frustration when it fails to thrive outside perfect settings. This purchase is best suited for experienced gardeners prepared to meet its specific requirements for site selection and winter care.
