About
Chamaenerion angustifolium 'Album' is a vigorous perennial that can reach heights of up to 1.5 meters. This plant establishes a broad colony through its rhizomatous roots, producing upright stems that may exhibit a subtle pink hue. Its foliage consists of elongated, narrow leaves reminiscent of willow. From mid-summer to early autumn, it produces spikes adorned with white flowers, each measuring around 2 centimeters in diameter. After flowering, it develops elongated seed pods that are tinged with pink, housing seeds enveloped in fine, silky fibers.
