Deverra triradiata is an aromatic perennial shrub distributed in coastal arid regions. In the present study, we tested the effect of umbel order on seed weight, germination, and germination requirements for temperature and light. Germination rate was strongly affected by umbel order and photoperiod but not by thermoperiod. Seed mass also declined substantially with umbel order. Results suggest that resource allocation within the inflorescence enables plants to produce seeds with a range of germination characteristics.
