Trimezia

( try - MEZ - ee - uh )

At-A-Glance Information

This genus of flowering perennials needs full sun or light shade and regular water to perform at its peak. They produce fans of leaves, similar to Iris plants, and flower stems that are about the same height as the rest of the foliage. Flowers have three large outer segments around three inner ones, and are banded in contrasting colors. Flowers last for only a day but are followed in time by new blooms.

Trimeza caerulea (Neomarica caerulea)
This native of Brazil grows to 5.5 feet tall and 2-3 feet wide, with erect leaves. Flower stems support blooms that are blue with centers banded in white, yellow and brown. Flowers pop in summertime along the stems, and can be removed and grown into full plants.

Trimezia candida (Neomarica candida) (White Walking Iris)
​These plants are native to Paraguay, Brazil, northeastern Argentina, and Uruguay. The species was first described by Emil Hassler. Flowers are white with purple, red, and yellow markings.

Trimeza fosteriana
These flowering bulbs produce delicate yellow flowers atop green flowering stems, and are widely used in cities in South America as garden ornamentals. The species is native to Venezuela, though plants are grown widely around the globe for their cold tolerance.

Trimezia gracilis (Walking Iris)
This species is native from Mexico to Brazil and reaches 2-2.5 feet tall and 1-1.5 feet wide. Flowers appear in late spring and summertime, and are held close to the foliage. Outer segments are white and inner segments are blue, brown and yellow. Plantlets form on stems which bend to the ground when they are ready to root, hence the common name. 

Trimezia humilis
Native to Venezuela and parts of Brazil. These flowers form strappy green above-ground foliage and produce light yellow flowers with red stripes and bright pink to magenta centers.
