  • Biennial (most common)
    The classic form produces only leaves in the first year and forms flowers in the second year.
  • Short-lived perennial
    Some plants continue to live for a few years after flowering and bloom again, especially in mild winters and well-drained soil.
  • Annual flowering variety.
    Modern cultivars have been specially bred to bloom profusely in the first year.
