Trimezia martinicensis - Yellow walking iris
About five species of Trimezia
are native to the Caribbean and South America.
This plant has iris-like leaves with yellow flowers that stand on spikes just
above the foliage. After flowering, the spike develops small plants. When the
spike falls over to the ground, these small plants root into the ground and
expand the clump.

These plants were donated by Jacksonville plant collector, Joyce Jarrell, to
test the species’ cold hardiness. This plant is reported by one source as hardy
in Zone 8. Experience shows that it is cold hardy at least to the mid-20’s F.
