Is a shamrock annual or perennial?

Shamrock plants can be either annual or perennial, depending on the species and growing conditions. The common shamrock, or Oxalis triangularis, is typically grown as a perennial in suitable climates, thriving year after year. However, in some regions, it may be treated as an annual due to cold temperatures. Overall, the lifespan of a shamrock plant can vary based on the specific variety and environmental factors.
