Giant butterbur + Grass pea
Petasites japonicus, also known as Fuki, bog rhubarb, or giant butterbur, is an herbaceous perennial plant in the family Asteraceae. It is native to Japan, where the spring growth is used as a vegetable. It has also been introduced to southern British Columbia by Japanese immigrants.

Lathyrus sativus, is a legume (family Fabaceae) commonly grown for human consumption and livestock feed in Asia and East Africa. It is a particularly important crop in areas that are prone to drought and famine, and is thought of as an 'insurance crop' as it produces reliable yields when all other crops fail.
Shared flavor compounds
These compounds appear in both Giant butterbur and Grass pea, giving them a molecular basis for flavor affinity, the pairing principle articulated by Francois Benzi and implemented in flavor-pairing research.
