Overview
The Lifesaver Plant (Huernia zebrina), famously known as the zebra-striped lifesaver or owl eyes, is an extraordinary, surreal succulent perennial native to the sun-scorched rocky landscapes of southern Africa. Belonging to the dogbane family (Apocynaceae) within the fascinating stapeliad tribe, this botanical marvel produces some of the most bizarre and instantly recognizable flowers on Earth. Featuring a star-shaped corolla striped in bold zebra bands surrounding a massive, glossy, raised rubbery ring that looks exactly like a glazed cherry lifesaver candy, H. zebrina represents an astonishing achievement in arid floral architecture.
Biology and Physical Characteristics
Huernia zebrina forms low, sprawling clumps of four-to-five-angled succulent stems that are pale grayish-green, often flushed with purple or reddish-bronze when exposed to intense desert sunlight. The stems are lined with fleshy, soft-pointed toothed tubercles. In late summer and autumn, the plant produces five-pointed star-shaped blossoms measuring up to two inches across. The corolla lobes are a warm sulfur-yellow or cream, dramatically banded with concentric, wavy horizontal stripes of deep burgundy-red. In the center of the blossom sits an extraordinary raised, circular fleshy ring (annulus) that is thick, highly glossy, and colored a deep, solid mahogany-red, giving the impression of an enamel confection.
Behavior and Ecology
Despite its sweet, candy-like visual appearance, the flower of Huernia zebrina operates under a sophisticated deceptive pollination syndrome (sapromyophily). The blossom emits a faint, musky scent of decaying animal tissue, which attracts female carrion flies and flesh flies. Flies drawn to the scent land on the slippery, glossy central annulus and crawl into the central cup searching for an egg-laying site; as they explore the corona, the plant’s specialized pollen clips (pollinia) latch firmly onto the fly’s legs or proboscis. Unlike large Stapelia flowers that emit overpowering odors, H. zebrina produces only a very subtle scent detectable primarily to keen insect antennae.
Conservation and Human Impact
Assessed as Least Concern by the IUCN and South African National Biodiversity Institute (SANBI), Huernia zebrina is widespread and locally common across its rugged southern African range. Its ability to thrive in poor, rocky quartz gravels and survive months of blistering drought protects it from agricultural land conversion. Moreover, because it is one of the easiest and most enthusiastically cultivated stapeliads in global horticulture, domestic propagation via stem cuttings satisfies hobbyist demand worldwide, preserving wild populations from commercial collection pressures.
Interesting Factoid
While the flower looks like a delicious glazed cherry lifesaver candy surrounded by zebra stripes, it actually smells faintly like rotting meat to trick unsuspecting desert flies into pollinating it!
