Acorus gramineus 'Minimus Aureus'
Common name: mini Ogon, Dwarf Golden Sweet Flag,
Japanese sweet flag, or Japanese rush (a.k.a. 'Wogon').
Zone: 5 to 9.
Sun to part shade, aquatic or wetland perennial.
Mature size: 3 to 6 inches tall.
Narrow, grass-like, dwarf plant has bright gold variegated leaf blades. Tiny, densely-packed, greenish-yellow flowers emerge in late spring to early summer. Iris-like tufts will spread to form a dense ground cover, but is not invasive.
Easily grown in average, moist to wet soil; grows in moderately moist conditions and boggy conditions, or shallow water. In hot summer climates, without afternoon shade or filtered sun, leaf tips may scorch if allowed to dry out. A regular watering schedule during the first growing season will help establish root system. Divide every 2 to 3 years in early spring.
Common name is sweet flag because of the aromatic, grass or iris-like foliage.
Great for containers, edging, between stepping stones or as a ground cover, and ideal in water gardens, along streams or ponds, or anywhere soil moisture requirements can be met. Maintenance free and deer resistant.
