What is the life span of a castor bean?

The life span of a castor bean plant (Ricinus communis) typically ranges from one to two years, depending on the growing conditions and climate. In favorable environments, such as tropical and subtropical regions, the plant can grow as a perennial, while in colder climates, it is often grown as an annual. The seeds, or castor beans, can remain viable in the soil for several years, allowing the plant to regenerate in subsequent growing seasons.
