A. g. ‘Variegatus’ is commonly called variegated Japanese rush, dwarf sweet flag or grassy-leaved sweet flag. It is a semi-evergreen, marginal aquatic perennial that features grass- to iris-like tufts of narrow, variegated leaf blades (1/4″ wide) which are striped with white and green and fan upward to 6-12″ tall. It thrives in wet soils and is commonly grown in water gardens and boggy areas as a foliage accent or ground cover. Although it looks like a grass or small iris, it is actually a member of the acorus family. Insignificant, sedge-like flower spikes (2-3″ long spadixes without showy spathes) are densely packed with tiny greenish flowers that bloom from late spring to early summer. Flowers give way to tiny fleshy berries. Tufts slowly spread by creeping roots to form a dense ground cover. Foliage is sweetly fragrant when bruised.
