The Trimezia steyermarkii or Yellow Walking Iris is a lovely old heirloom plant with a long and rich pass-a-long history. It has graced the shaded areas of homesteads, farms, ranches and plantations across the Tropical and Sub-Tropical Americas and outlying islands for many generations.

There is general agreement that this species is native to areas of Central and South America and the Caribbean.  It is widely cultivated and naturalized across the New World , but there are differing opinions as to just exactly where the natural, native habitat ends and the areas where it was introduced begin. Florida is an an example, as it can be found seemingly growing wild in low lying areas, experts disagree as to exactly and how and when it came to grow there.

This type is frequently confused with two others, Neomarcia longifolia and Trimezia martinicensis. Neomarcia longifolia appears to simply be a case a mistaken indentification, as there currently seems to be some degree of horticultural agreement (which can be hard come by when it come to botanical taxonomy) that this plant belongs to the Trimezia genus rather than Neomarcia.   The differences are subtle and both groups share the propensity to readily reproduce themselves by producing new shoots along long arching stems that develop into a new plants a short distance away. But there are differences in the shape and structure of both the flowers, fronds and supporting root systems.

Trimezia martinicensis is a very similar, but seperate species with a few notable differences in the color and structure of the flower.

Both are commonly called a Walking Iris because the long stem where the short lived flowers are born arch over and touch the soil when the bloom is spent, and new a plantlet will form, so they will quickly walk outward and establish a new plant a short distance away.

The foliage is long, straight, flat, lance like fronds that grow in a clump, and mature at a height of about 18 to 24 inches. In the early spring the plant puts up long stems topped with fat yellow buds. They open into beautiful, small orchid-like iris flowers with a bright yellow body with a brown speckled throat. Once the buds fully open, the flowers are short lived, lasting a day or two at most. But what they lack in longevity and size they make up for in quantity and color.  A few weeks later, a new plant will begin to grow along the stalk of the spent flower.

Starter size plants can be successfully transplanted directly into the landscape so long as irrigation is monitored closely and there is no danger of frost and freeze during the establishment period. The Yellow Walking Iris can also be grown as potted plant indefinitely.

For the best results, here are a few suggestions for successful growing within the recommended USDA Zone Range (8, 9, 10, 11).

  •     Plant in fertile, rich, slightly acidic soil that is high in organic material. Amend the planting area as      necessary.
  •     Apply a good quality slow release general purpose fertilize with the initial planting and yearly in the early Spring there after.
  •     Provide supplemental irrigation, and monitor to maintain consistent, uniform moisture in the plant root zone. (Caution – surrounding soil can sometimes wick water out of the root ball for the first several week. Monitor the existing root ball closely during the establishment period.
  •     Plant early in the season in Zones 8 and 9A, or be prepared to protect from frost and freeze the first season. Well established plants are cold hardy to about 20ºF.
  •     Harvest and replant new plantlets to thicken or expand the bed faster, or let them walk and wander on their own.
  •     Enjoy!
