History
Astilboides tabularis is the sole species in its genus, endemic to shaded moist forests in northeastern China and North Korea. Russian botanist Carl Maximowicz first collected it during his 1859-1864 Amur Basin expedition and originally described it as Saxifraga tabularis in 1867. The plant was shuffled through Rodgersia before Austrian botanist Adolf Engler established the monotypic genus Astilboides in 1973 based on unique floral characters.
Its dramatic peltate leaves up to 36 inches across, attached at the center like an umbrella, earned its common name shieldleaf. Plantsman Ernst Pagels and other German gardeners popularized it in the late 20th century as a focal specimen for moist woodland gardens and pond margins.
Native to Korea and northern China, introduced to Western gardens in the early 1900s. A specialty plant in American bog and water gardens, championed by designers such as Dan Hinkley at Heronswood Garden in the Pacific Northwest.

It is a classic pond-side statement plant, lending tranquility to water gardens with sheer scale rather than fussy bloom. Where other plants chatter, Astilboides simply spreads its leaves and lets the koi do the talking.
