]. 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[

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[

Propagation

Seed - pre-soaking the seed for 12 hours in warm water can help to reduce germination time. If you have sufficient seed then it can be sown in situ. Otherwise sow in trays in a nursey and, when the seedlings are large enough to handle, pot them up into individual pots. Plant out when 15cm or more tall.
