Family: Asparagaceae
Origin, Description & Uses:
Lachenalia reflexa, commonly known as yellow soldier, is a small bulbous plant native to South Africa. It is part of a group of ornamental species valued for their bright, tubular yellow flowers that appear on upright stalks, often in late winter to early spring. The plant typically has strap-like or slightly wavy leaves and is well-suited to container growing or rock gardens. Due to its compact size and striking floral display, yellow soldier is occasionally cultivated by plant enthusiasts and collectors seeking unique ornamental bulbs for warm, dry climates.
Risks & Threats:
Although Lachenalia reflexa is not currently known to be naturalized in the Hawaiian Islands, it possesses traits that raise concern for tropical environments. As a bulb-forming species capable of vegetative reproduction and persistence in suitable climates, it may establish outside of cultivation if introduced. In regions with similar conditions, related species have shown the ability to spread and compete with native vegetation. If established in Hawaiʻi, yellow soldier could potentially disrupt native plant communities, particularly in dry or disturbed habitats. For these reasons, it is recommended to avoid planting this species and instead choose a low-risk or native alternative better suited to protecting Hawaiʻi’s unique ecosystems.
High Risk Traits:
- Naturalized outside native range
- Environmental weed
- Congeneric weed
- Geophyte (bulbs, corms, tubers)
- Produces viable seed
- Self-compatible or apomictic
- Minimum generative time = 1 year
- Propagules dispersed intentionally by people
- Propagules water dispersed
- Prolific seed production (>1000/m²)
- Persistent seed bank (>1 year)
- Tolerates mutilation, cultivation, or fire
- Poorly controlled by herbicides
- Shade tolerant
Low Risk Traits:
- No spines, thorns, or burrs
- Not toxic to animals or humans
- No vegetative fragmentation
- No unintentional dispersal (traffic, produce, wind, birds, animals, gut passage)
