New plantlets form at the end of the flower spikes. After flowering, the spikes fall over and a new plant grows, so the plant “walks” (therefore, another name for Apostle plant is “Walking iris”).The name “Apostle plant” refers to the incorrect belief that Trimezia plants do not flower until 12 or more leaves are present.
