Astilbe × arendsii 'Irrlicht' - 2026

Astilbe × arendsii 'Irrlicht' is a graceful perennial prized for its upright plumes of pure white flowers that bloom in midsummer above dark green, finely divided foliage. Its feathery flower spikes create a delicate, textured display, adding elegance and brightness to shaded borders, woodland gardens, or pondside plantings. The long-lasting blooms and ornamental foliage provide sustained visual interest, making it ideal for group plantings or mixed perennial borders.

Thriving in humus-rich, consistently moist soil, it prefers partial to full shade and benefits from regular watering during dry periods. Low-maintenance and reliable, 'Irrlicht' requires only cutting back spent stems after flowering and occasional mulching to retain soil moisture. Its nectar-rich flowers attract pollinators, enhancing both ornamental and ecological value in shaded garden spaces.
