Hurricane Grass, Fimbristylis spathacea

“All Crotalaria species are poisonous if ingested due to the presence of pyrrolizidine alkaloids. Keep away from small children, pets and livestock. Despite the toxicity, plants in this genus are larval hosts for the Ceraunus blue butterfly and the Bella moth (also known as the Rattlebox moth). The latter relies on the plant?s toxic alkaloids, which it obtains from the seeds, for its brilliant colors.” – Florida Wildflower Foundation. Highly salt-tolerant, moderate to high concentrations of salt in the soil or water. – FNPS
