Amethyst Astilbe Plant

Astilbe arendsii 'Amethyst' produce the characteristic feathery plumes of the False Spirea, but with blossoms of a most noticeable and remarkable amethyst color. This full-leafed variety makes a beautiful backdrop for your shorter or more sparsely foliaged plants. Amethyst is shipped as a bare root, a method we favor for its ability to establish quickly, double in size compared to its potted counterparts within the first season, and omit the necessity for plastic pots—providing an eco-friendly advantage.

Our Astilbe Plants are cultivated with care, ensuring they are free from harmful pesticides and safe for your garden and the environment. Guaranteed to arrive alive and thriving!
