Quick Overview:

This grassy-leaved sweet flag cultivar is a miniature or dwarf plant which looks like a grass but is actually a member of the acorus family. Features tufts of yellow grassy-like leaf blades which grow to only 3-4″ tall and slowly spread by creeping roots to form a mat of golden foliage. Foliage is sweetly fragrant. Insignificant, sedge-like flower spikes (spadixes) of tiny, densely-packed, greenish-yellow flowers appear in spring. Flowers give way to tiny fleshy berries. Commonly called grassy-leaved sweet flag because of the aromatic, grass/iris-like foliage.


Easily grown in average, medium to wet soils in full sun to part shade. Best in light shade. Grows well in both boggy conditions (including very shallow water) and in moist garden soils. Scorched leaf tips will occur if soils are allowed to dry out. Appreciates some relief from hot summer sun (e.g., afternoon shade or filtered sun) when grown in hot summer climates. Slowly naturalizes by spreading roots.
