Native to China and Japan, this spectacular genus will grow in ordinary garden soil, but give it a rich moist home along a pond, stream or marshy area and it will thrive. Rodgersias are fine structural specimens characterized by brownish black fleshy rhizomes, which remain visible through winter. The numerous unpetaled flowers, colored by intriguing creamy salmon sepals and stamens, are borne on large panicles, and when in bud look almost like miniature cauliflowers. And, be warned! The textured, dark green leaves can spread to a foot across, so be sure to provide these plants with plenty of space.
A 1974 Ernest Pagels introduction, ‘Smaragd’ translates to emerald, aptly describing the eye-catching lime-green hues that brighten large tropical-looking leaflets. Jagged toothed margins, broad lobed tips and heavy venation further embellish the lush foliage beneath a marvelous summer display of alabaster-colored Astilbe-like flowers. Infused with cozy bronze tones when young, this somewhat smaller-sized cultivar recently earned a 4-star rating in the Chicago Botanical Garden trials for its consistently robust, winsome bearing.
