Despite the long, tongue-twisting name, the dwarf golden sweet flag is one of the most striking and certainly the cutest of the acorus. The tufts of tiny, golden, grasslike, evergold foliage make a slowly spreading patch to 2' wide in 5 years. If you get out the magnifying glass, you'll notice the tiny aroid-like tan spadices (flowers) in early summer. Acorus 'Minimus Aureus' is a bright deer-resistant dwarf groundcover in moist areas where it makes either a feature specimen or a killer filler between dark stepping stones...a real highlight in the woodland garden.
