Ornamental Features

Walking Iris has spikes of fragrant white orchid-like flowers with burgundy throats and blue stripes rising above the foliage from mid spring to mid fall, which are interesting on close inspection. The flowers are excellent for cutting. Its sword-like leaves remain dark green in color throughout the season. The fruit is not ornamentally significant.

Landscape Attributes

Walking Iris is an open herbaceous perennial with a shapely form and gracefully arching foliage. Its relatively coarse texture can be used to stand it apart from other garden plants with finer foliage.

This is a relatively low maintenance plant, and should not require much pruning, except when necessary, such as to remove dieback. It has no significant negative characteristics.

Walking Iris is recommended for the following landscape applications;

  • Accent
  • Mass Planting
  • General Garden Use
  • Container Planting

Planting & Growing

Walking Iris will grow to be about 24 inches tall at maturity extending to 32 inches tall with the flowers, with a spread of 24 inches. When grown in masses or used as a bedding plant, individual plants should be spaced approximately 12 inches apart. It grows at a fast rate, and under ideal conditions can be expected to live for approximately 10 years.

This plant does best in partial shade to shade. It prefers to grow in average to moist conditions, and shouldn't be allowed to dry out. It is particular about its soil conditions, with a strong preference for sandy, acidic soils. It is somewhat tolerant of urban pollution. This species is not originally from North America. It can be propagated by multiplication of the underground bulbs.

Walking Iris is a fine choice for the garden, but it is also a good selection for planting in outdoor pots and containers. Because of its height, it is often used as a 'thriller' in the 'spiller-thriller-filler' container combination; plant it near the center of the pot, surrounded by smaller plants and those that spill over the edges. Note that when growing plants in outdoor containers and baskets, they may require more frequent waterings than they would in the yard or garden.
