Retama monosperma forms root nodules with Sinorhizobium fredii. The larvae of the moths Phyllonorycter hesperiella and Phyllonorycter spartocytisi feed on R. monosperma.

The seeds contain cytisine, a toxic alkaloid. Fifteen other quinolizidine and three dipiperidine alkaloids can also be isolated from different parts of the plant. In particular, the presence of (+)-sparteine, α- and β-isosparteine, (+)-17-oxosparteine, (-)-lupanine, 5,6-dehydrolupanine, (-)-anagyrine, (-)-N-methylcytisine and (+)-ammodendrine can be detected.[2]
