Japanese Sweetflag

Acorus gramineus

Acorus

Grassy-Leaved Sweet Flag

Named for the pleasant pine-like fragrance emanating from its dapper semievergreen fans, Acorus is actually not a grass, but rather a grassy-looking herbaceous perennial. This deer-resistant Asian denizen eventually forges a dense trouble-free ground cover of waxy, upright flattened blades that grow from slow-creeping rhizomes. Recently included in the Acoraceae family and once used as an aromatic addition to gin, beer and perfumes, it craves consistently moist soil, flourishing in both boggy situations and even shallow standing water.

<i>Acorus gramineus</i>

An arching grass-shaped perennial from the moist environs of Japan, Korea and eastern Asia, semievergreen Japanese Sweetflag renders flattened, fan-like tufts supported by slow-spreading rhizomes. Narrow, 3 inch long champagne-hued blooms embellish the slender, sword-style lime-green leaves. Lauding cheer, sweet scents plus easy-care versatility, this lustrous Acorus is an elegant low growing choice for bogs, containers, cottage gardens, waterside areas and en masse plantings in modern venues, where it abates erosion, enjoys protection from hot afternoon sun and toughs partially submerged haunts.

Blooms April–June

Size: 6" – 12" high x 6" – 12" wide.
