About
Bistorta 'Pink Elephant' is a compact, semi-evergreen perennial that typically reaches a height of 65 cm. It features slender, leathery leaves of a deep green hue. From mid-summer into autumn, elongated spikes adorned with small, bell-shaped pink flowers emerge, elegantly arching above the foliage. Despite its vigorous growth, this variety of Persicaria remains manageable and does not become invasive. It thrives in containers placed in lightly shaded, cool areas, making it a good choice for smaller gardens or for positioning at the front of flower borders.
