History

Illustrated historical scene for False-Buck's-Beard

Astilbe japonica is native to the main islands of Japan. German physician Philipp Franz von Siebold collected it during his residency at Dejima in Nagasaki (1823-1829) and introduced it to Leiden Botanic Garden by 1837. Dutch nurseries distributed it throughout Europe, where it was initially grown as a curiosity.

German plantsman Georg Arends (1863-1952) at Ronsdorf systematically crossed A. japonica with A. chinensis, A. thunbergii, and A. astilboides beginning in 1907, creating hundreds of cultivars under the collective name Astilbe x arendsii. These hybrids—including 'Rheinland', 'Deutschland', and 'Europa'—became iconic European shade perennials. Modern breeding at Walters Gardens and European nurseries continues to expand color and form based on these Siebold-era introductions.
