Safety & Hazards

No specific mention of toxicity has been seen for this species, but many members of this genus are known to contain pyrrolizidine alkaloids, the most potent of which in this genus are monocrotaline, retrorsine and retronecine[1]. These alkaloids have a cumulative effect upon the body and, unless concentrations in a plant are high, occasional consumption is generally completely safe. Pyrrolizidine alkaloids are derived from amino acids including ornithine. Many of these alkaloids have pronounced hepatic toxicity, but the lungs and other organs may be affected as well. Mutagenic and carcinogenic activities of pyrrolizidine alkaloids have also been reported[2].

Cultivation Details

HabitAnnual
Growth—

Annual and short-lived perennial plants in this genus generally gow best in a sunny position, succeeding in most dry to moist, well-drained soils[3]. We have no specific report for this species, but most species in this genus have a symbiotic relationship with certain soil bacteria; these bacteria form nodules on the roots and fix atmospheric nitrogen. Some of this nitrogen is utilized by the growing plant but some can also be used by other plants growing nearby[4].

Propagation

Seed - sow in situ. Pre-soaking the seed for 12 hours in warm water can help to reduce germination time. Cite as: Tropical Plants Database, Ken Fern. tropical.theferns.info. 2026-02-20. <tropical.theferns.info/viewtropical.php?id=Crotalaria+cobalticola>
